ACTION: Revised Mandatory Guidelines
SUMMARY: The Department of Health and Human Services (HHS) revises some
of the scientific and technical guidelines for Federal drug testing programs
and revises certain standards for certification of laboratories engaged in
urine drug testing for Federal agencies.
EFFECTIVE DATE: September 1, 1994
FOR FURTHER INFORMATION CONTACT: Dr. Donna M. Bush, Chief, Drug Testing
Section, Division of Workplace Programs, Substance Abuse and Mental Health
Services Administration (SAMHSA), Room 13A-54, 5600 Fishers Lane, Rockville,
Maryland 20857, tel. (301) 443-6014.
SUPPLEMENTAL INFORMATION: The Department is revising the guidelines
entitled "Mandatory Guidelines for Federal Workplace Drug Testing Programs,"
(Mandatory Guidelines) which were initially published in the Federal Register
on April 11, 1988 (53 FR 11979). These Mandatory Guidelines and the revisions
are developed in accordance with Executive Order No. 12564 dated September 15,
1986, and section 503 of Pub. L. 100-71, 5 U.S.C. section 7301 note, the
Supplemental Appropriations Act for fiscal year 1987 dated July 11, 1987. The
revisions to the Mandatory Guidelines incorporate changes based on the comments
submitted and the Department's first 5 years of experience in implementing and
administering these Guidelines.
BACKGROUND AND SUMMARY OF PUBLIC COMMENTS AND POLICIES OF THE REVISED GUIDELINES:
A. Proposed Revised Mandatory Guidelines
The basic purpose of the Mandatory Guidelines is to establish scientific and
technical guidelines for Federal agencies' workplace drug testing programs and
to establish a certification program for laboratories engaged in urine drug
testing for Federal agencies. The proposed revisions published in the Federal
Register on January 25, 1993 (58 FR 6062), retained the basic
requirements in the Mandatory Guidelines published in the Federal Register
on April 11, 1988, but as indicated above refined some requirements in order to
incorporate changes based on the Department's first 5 years of experience in
implementing and administering these Guidelines.
The major changes proposed in the notice published in the Federal Register
on January 25, 1993, are summarized here to facilitate the discussion of the
comments received during the public comment period.
The Department proposed reducing the requirement to collect 60 mL of urine at
the collection site to 30 mL. This change was proposed because many times
donors have difficulty in providing the 60 mL of urine. In addition, 30 mL is
adequate to complete the required testing and satisfy other program
requirements.
The Department proposed to revise the specimen collection procedure to allow
Federal agencies to use an optional "split specimen" collection procedure.
Several Federal agencies have been granted waivers to use split specimen
collection procedures during the past 5 years. Establishing a "split specimen"
procedure will ensure that each Federal agency will be using the same
procedure. The Department believes that appropriate guidance must be provided
regarding the minimum acceptable volumes for the split specimens, measuring
temperature before a single donor specimen is transferred into two separate
specimen bottles, sending both split specimen bottles to the laboratory at the
same time to ensure that they are subject to the same shipping and storage
conditions, and specifying the procedures for testing Bottle B when the Bottle
A specimen is reported positive.
The Department proposed to revise the collection procedure to allow Federal
agencies to use an individual of the same gender, other than a collection site
employee, to observe the collection of a specimen whenever there is reason to
believe the individual may have altered or substituted the specimen. This
change is based on the understanding that it is not always possible to have a
collection site employee of the same gender observe the collection.
The Department proposed a change to allow a laboratory to use a certifying
scientist who is only certified to review initial drug tests which are
negative. This could assist in reducing the cost of testing without
compromising the reliability of drug testing.
The Department proposed that the initial test level for marijuana metabolites be
reduced from 100 ng/mL to 50 ng/mL. This change reflects advances in technology
of immunoassay tests for marijuana metabolites.
The Department proposed to allow laboratories to use multiple immunoassay tests
for the same drug or drug class. This would allow laboratories to use an
initial test and then forward all presumptive positives for a second test by a
different immunoassay technique to minimize possible presumptive positives due
to the presence of structural analogues in the specimen. In addition, this
policy would allow a laboratory to use a different immunoassay for specimens
that may be untestable with one immunoassay.
The Department proposed that in order to report a specimen positive for only
methamphetamine, the specimen must also contain the metabolite amphetamine at a
concentration equal to or greater than 200 ng/mL by the confirmatory test. This
proposed requirement would ensure that high concentrations of sympathomimetic
amines available in over-the-counter and prescription medications will not be
misidentified as methamphetamine.
The Department proposed reducing the number of blind samples a Federal agency
must submit each quarter to its contracting laboratory from 10% of all samples
to a minimum of 3% (with a maximum of 100 blind samples). This proposed change
may significantly reduce the costs associated with maintaining a blind sample
program without affecting the Federal agency's ability to monitor a
laboratory's performance.
The performance testing sample portion of the laboratory certification program
was proposed to be changed by reducing the performance testing (PT) challenges
for certified laboratories from 6 cycles per year to 4 cycles per year.
Experience in this and other performance testing programs indicates that 4
cycles per year is sufficient to assess a laboratory's ability to test and
report results for performance testing samples.
The Department proposed restricting the types of arrangements that can exist
between the Medical Review Officer (MRO) and the laboratory to ensure that a
conflict of interest does not exist. The restrictions would require that the
agency's MRO not be an employee or an agent of, or have any financial interest
in, the laboratory for which the MRO is reviewing drug testing results.
Similarly, the laboratory would be prohibited from entering into any agreement
with an MRO that could be construed as a conflict of interest.
A new subpart D was proposed which provides detailed procedures for the internal
review of a suspension or proposed revocation of a laboratory's certification
to perform drug testing. These procedures will ensure and provide a timely and
fair review of all suspensions or proposed revocations.
The Department proposed that the written notice of the suspension which is sent
to the laboratory, as well as the reviewing official's written decision
upholding or denying suspension or proposed revocation under the review
procedures in subpart D, would be made available to the public upon request.
This provision ensures that the public has access to the documents containing
the basis for HHS's actions.
B. Public Comments and the Department's Responses
The Department received 73 public comments on the proposed changes from Federal
agencies, individuals, organizations, and companies. About 50% of these
supported all or some of the proposed changes. All written comments were
reviewed and taken into consideration in the preparation of the revised
Mandatory Guidelines. The substantive concerns raised in the public comments
and the Department's responses to the comments are set out below. Similar
comments are considered together.
1. Definitions
A number of commenters expressed concerns with the definitions in section 1.2.
It was suggested that the definition for chain of custody indicate that
couriers do not need to document chain of custody while the specimens are in
transit to the laboratory. The Department agrees that the Mandatory Guidelines
should be clarified to address that issue.
Specimens are sealed in packages and any tampering with a sealed specimen would
be noticed by the laboratory and documented on the specimen chain of custody.
In addition, as a practical matter, couriers, express couriers, and postal
service personnel do not have access to the specimen chain of custody form
since the form is inside the sealed package. Section 2.2(i) of the Mandatory
Guidelines that discusses the transportation of a specimen to a laboratory has
been revised to clarify this point.
One commenter recommended that the definitions in the Guidelines conform to the
definitions established by the National Committee for Clinical Laboratory
Standards (NCCLS) since the proposed definitions may be in conflict with the
efforts of that nonprofit, educational organization. The Department fully
supports the efforts of this committee to develop standard definitions since a
common understanding of definitions is essential for maintaining a high level
of performance within laboratory testing programs. The Department has revised
the definitions in section 1.2 to ensure that they are consistent with those
proposed currently by NCCLS. The Department has changed the proposed
definitions for calibrator, control, and standard as well as included new
definitions for donor, specimen, sample, and quality control sample. The
Department also made appropriate changes in other sections of the Guidelines to
ensure that the terms used were consistent with these new definitions. The
Department notes, however, that these changes are not substantive, but rather
are technical in nature to clarify the definitions. The Department believes
these changes will eliminate the confusion expressed by several other
commenters regarding the use of these terms in other sections of the
Guidelines.
One commenter believes the proposed definition for the certifying scientist
should specifically state that the individual understands chain of custody. The
Department intended that the definition of certifying scientist include that
the individual have a thorough understanding of chain of custody, since it was
proposed that such individual have "training and experience in the theory and
practice of all methods and procedures used in the laboratory." See section
1.2. However, in order to prevent any confusion, the definition has been
changed to clarify this issue. One commenter suggested that the Secretary
require a certifying scientist to possess at least a masters degree, so they
would be equal to experts presented by an employee who is contesting the result
in court or in an administrative proceeding. Based on the Department's
experience, there are numerous highly qualified individuals serving as
certifying scientists who possess bachelors' degrees, and who have the
expertise to testify as to the records they have certified. These certifying
scientists do not need to be qualified as experts in litigation, as the defense
may qualify someone else in the laboratory or outside the laboratory to perform
this function, if necessary. Further, the Department believes that requiring
higher educational requirements would place an unnecessary burden on the
laboratories, as well as eliminate many qualified individuals from serving as
certifying scientists.
One commenter believes the requirement to use an Office of Management and Budget
(OMB) approved specimen chain of custody form requires the laboratories to use
OMB approved laboratory chain of custody forms. This interpretation is
incorrect. The Department proposed that such forms be used only for specimen
chain of custody forms, not laboratory chain of custody forms. The Department
believes that standard specimen chain of custody forms are important to ensure
that collection sites have a consistent form so as to reduce any errors or
incomplete documentation when filling out the forms.
One commenter noted that the Department's proposed definition of an immunoassay
test is ambiguous and does not support the policy that allows using a second
immunoassay test for specimens that are presumptively positive for
amphetamines. Specifically, the term "initial test" was proposed to be defined
as "[a]n immunoassay test to eliminate "negative" urine specimens from further
consideration and to identify the class of drugs that requires confirmation."
The Department agrees with the commenter that the definition is ambiguous. The
Department supports allowing laboratories to perform multiple immunoassay tests
for the same drug or drug class. Therefore, the Department has clarified the
definition to ensure that further testing is consistent with section 2.4(e)(4)
which permits conducting multiple initial tests.
2. Dilution/Adulteration Tests
Several commenters concurred with section 2.1(c) which clarifies that
laboratories may conduct dilution/adulteration testing to determine the
validity of the specimen while some commenters sought to have the Secretary
define the specific tests to be conducted and require that such tests be
performed. The issue regarding the types of dilution/adulteration testing to be
performed has been highly controversial among forensic laboratory professionals
since there is a lack of data to suggest that dilution/adulteration testing can
clearly identify a donor who has intentionally taken a substance to affect the
outcome of a drug test or has otherwise diluted or adulterated the specimen. At
this time, the Department believes that such testing should remain optional and
the selection of tests to be conducted for possible dilution/adulteration and
the cutoff levels for such tests, if conducted, should be determined by the
laboratories based on their best judgment.
Two commenters requested that the Department allow dilution/adulteration testing
to be conducted at the collection site. The Department believes that it is
better able to monitor the performance of such testing when it is conducted by
laboratory personnel, rather than require agencies to monitor such testing at
the collection sites. During the laboratory inspection process, the Department
is able to evaluate the laboratories' performance of such testing to ensure
that tests are performed properly, chain of custody is not broken, and
cross-contamination does not occur from one donor specimen to another which
could impact the integrity of a specimen. The MRO can review the results of the
dilution/adulteration tests and make a decision on the basis of the test and on
his or her interview of the donor to determine whether a medical factor may
have contributed to the results of such testing. In addition, disallowing the
use of dilution/adulteration testing at the collection site ensures that agency
employees are not unnecessarily subject to observed collection and thus
protects the privacy of individuals to the maximum extent possible.
3. Specimen Collection Procedure
With regard to the specimen collection procedure, a number of commenters were
highly supportive of reducing the required volume of a urine specimen from 60
mL to 30 mL as stated in section 2.2(f)(10). One commenter, however, expressed
concern that 30 mL is insufficient when dealing with a specimen that is
positive for more than one drug. That may be the case in some cases.
Nevertheless, the number of specimens that are positive for more than one drug
is very small and most volumes collected generally exceed 30 mL. The Department
believes this reduced volume requirement will make it easier for an individual
to provide a urine specimen with sufficient volume on the first attempt rather
than requiring the collection of a second specimen after drinking a reasonable
quantity of liquid. It is noted that the policy of combining additional urine,
after drinking a reasonable amount of liquid, with a partial specimen (i.e., an
insufficient volume of urine on the first void) has been eliminated. The
Department believes the reduced volume requirements will ensure that a
sufficient volume is collected on the first void and combining partial
specimens will not be necessary.
One commenter expressed concern over the fact that the Mandatory Guidelines did
not specify limitations or guidance as to the amount of liquid to be given a
donor who could not provide a 30 mL urine specimen. The commenter expressed
concerns regarding the possible risk of water intoxication if there is no limit
established for the amount of liquid that can be provided. The Department
concurs and has changed the example given in section 2.2(f)(10) to read "(e.g.,
an 8 oz glass of water every 30 minutes, but not to exceed a maximum of 24
oz)." The example provided describes a reasonable amount of liquid to be
provided and the Department would expect collection sites to use reasonable
care in its determination of the amount of liquid to provide donors.
Several commenters noted that the temperature range stated in the proposed
revisions did not agree with the range stated in the introductory discussion of
the proposed changes. A notice correcting the error was published in the Federal
Register on March 1, 1993. The correct temperature range is "32 -38 /90
-100 F."
There was general agreement that the marginally wider temperature range will not
adversely affect the ability to detect a donor who may possibly tamper with the
specimen. Two commenters, however, believe that the lower limit of the
temperature range should be increased. The Department does not agree with this
recommendation. A urine specimen provided in a collection cup that is at room
temperature will cool quickly; therefore, a narrow temperature range will
significantly increase the number of specimens that will not satisfy the
temperature range requirements. This would cause numerous unnecessary
collections of second specimens and falsely raise suspicions that many donors
have tampered with their specimens.
With regard to the collection of a urine specimen when using direct observation,
one commenter suggested that the employee's agency choose the observer if there
is no collection site person of the same gender available. The Department
agrees and sections 2.2(f)(13), 2.2(f)(16), and 2.2(f)(23) have been revised to
include this requirement. The Department believes that the agency will select
an individual who will act responsibly and reliably so as not to substantiate
any allegation to the contrary by an employee.
One commenter believes that only trained collectors should be involved in the
collection procedure, especially when direct observation is required. The
Department acknowledges that trained personnel should be involved in the
collection of urine specimens; however, it is not always possible to ensure
that a trained collection site person of the same gender will be available when
a direct observation is required. Allowing the agency to select an individual
to act as the observer, when there are unusual circumstances, ensures that the
collection will occur promptly and as scheduled rather than delaying the
collection unnecessarily.
One commenter believed that observed collection should never be used in any
circumstances. The Department disagrees. The Department continues to believe
that observed collection is justified and necessary when there exists
reasonable suspicion to believe that the donor altered or substituted the
specimen. Observed collections do not occur frequently. However, the Department
believes that any invasion of a donor's privacy is greatly outweighed by public
health and safety concerns in such cases.
One commenter recommended that we refer to the individual providing the urine
specimen as the "donor." The Department concurs with the recommendation and has
replaced the word "individual," when it refers to the person providing a urine
specimen, with the word "donor" throughout the Guidelines. A definition for
donor has been included in section 1.2. In addition, the use of the word
"donor" is consistent with its use on the specimen chain of custody form.
One commenter suggested that the entire collection procedure be revised
substantially to provide more specific guidance to agencies on the collection
process. The Department believes the procedure, as described, provides
sufficient guidance to the agencies on the collection process, including
factors to ensure that urine specimens are collected properly and satisfy chain
of custody requirements. The changes made in the Mandatory Guidelines with
regard to the single specimen collection procedure and the optional split
specimen procedure should clarify the procedures and, thereby, address many of
the concerns raised by this commenter without completely revising and expanding
the descriptions of the collection procedures.
Many commenters concurred with including an optional split specimen collection
procedure. They believed it was important to include split specimens since the
Omnibus Transportation Employee Testing Act of 1991, Title V of Pub. L.
102-143, requires using a split specimen collection procedure for industries
regulated by the Department of Transportation (DOT). This is particularly
important since Federal employees from a number of Departments will be subject
to both the requirements of DOT (49 CFR Part 40) and the requirements of the
Mandatory Guidelines and Executive Order 12564 (September 15, 1986).
Two commenters suggested allowing the use of two or three containers to collect
split specimens. The Department agrees with this recommendation and has revised
the collection procedure to indicate clearly that either a specimen bottle or a
specimen container may be used when collecting urine specimens. However, when
using a split specimen collection procedure, it is not acceptable for a donor
to provide the split specimens by urinating directly into both Bottle A and
Bottle B. The specimen must be provided by urinating into only one container or
into Bottle A. After the temperature is measured, if the specimen was provided
directly into Bottle A, an appropriate amount is poured into Bottle B. If a
specimen container was used, appropriate amounts are poured from the specimen
container into both Bottle A and Bottle B. For split specimen collections, this
procedure ensures that the specimens in Bottle A and Bottle B are identical, it
is easier to measure the temperature of a single specimen rather than to
measure the temperature of two specimens that were collected in separate
containers, and it is easier for a donor to provide one specimen in a single
container/bottle rather than into two separate bottles. It was suggested by
several commenters that we specify the amount of urine to be poured into Bottle
B. We concur with that recommendation and have changed section 2.2(h)(3) of the
split specimen procedure to specify that a minimum of 15 mL of urine shall be
poured into Bottle B. Since Bottle B will only be tested for a specific
substance(s), 15 mL is sufficient to conduct the testing and to allow a
sufficient quantity to be retained frozen if Bottle A is reported positive.
Additionally, section 2.2(h)(1) has been changed to specify that a minimum of
45 mL of urine is required when using a split specimen collection procedure
rather than the 30 mL minimum when using the single specimen collection
procedure.
One commenter was concerned with the handling and storage of the split specimen
(Bottle B) after the Bottle A specimen is shipped to the laboratory. We agree
that the wording in section 2.2(h)(5) of the split specimen collection
procedure regarding refrigerating the specimens was confusing and it has been
revised. The Department believes that the most efficient and cost effective way
to handle split specimens is to send both the Bottle A and Bottle B specimens
to the laboratory at the same time including the appropriate specimen chain of
custody forms. This procedure will ensure the integrity of both Bottle A and
Bottle B. This procedure is also simpler and more cost effective than one which
would require the collection site to retain Bottle B specimens until the
results for the Bottle A specimens are reported by the MRO to the agency and
the agency notifies the collection site to either discard the Bottle B
specimens or to ship a specific Bottle B specimen to another certified
laboratory. When both specimens are received by the laboratory, Bottle A is
normally tested within one day and, if positive, both Bottle A and Bottle B can
be placed in secure, refrigerated storage until the confirmatory test is
completed. This procedure will ensure that both specimens are treated
essentially the same and subject to similar storage conditions until the
testing is completed.
Several commenters were concerned with the impact that a failed to reconfirm
result on the Bottle B specimen would have on a donor since personnel action
may have been taken based on an MRO verified positive result for Bottle A.
Although a failed to reconfirm result for Bottle B requires the MRO to void the
test result for Bottle A and an agency may be required to reverse any personnel
action that may have been taken, we believe failed to reconfirm reports will
occur infrequently and this possibility should not be the basis for an agency
to delay any personnel action. The Department believes that removing an
employee, for example, from a safety- sensitive position which may impact
public health and safety outweighs the minimal possibility that the testing of
Bottle B will not reconfirm the presence of a drug or metabolite.
In view of the comments, section 2.2(h)(6) has also been clarified to indicate
the MRO's responsibility to report a positive result for Bottle A. When an MRO
has verified the test of the first specimen bottle (Bottle A) as a positive
result, the MRO must report the result to the agency without waiting for the
donor to request that the Bottle B specimen be tested.
Several commenters expressed concern regarding the actions taken when a second
laboratory fails to reconfirm the presence of a drug or metabolite in the
second specimen bottle (Bottle B) in a split specimen collection. Since the
Bottle B specimen is tested without regard to the cutoff levels, the result
reported by the second laboratory is not reported as a negative or positive
result, but reported as either reconfirmed or failed to reconfirm the presence
of a drug or metabolite. The Department agrees that if this situation occurs,
an investigation must be conducted. The Department has added this requirement
in section 2.2(h)(8) of the Mandatory Guidelines and has required the MRO to
notify the donor's agency. In addition, the Federal agency must contact the
Secretary and the Secretary will investigate the failed to reconfirm result and
attempt to determine the reason for the inconsistent results between Bottle A
and Bottle B. HHS will report its findings to the Federal agency and ensure
that appropriate action is taken to prevent the recurrence of the failed to
reconfirm result.
Some commenters simply did not like permitting Federal agencies to have the
option of a split specimen procedure, believing, for example, that the use of a
split specimen procedure gives the perception of a lack of confidence in the
results when using a single specimen collection, that the additional
administrative and collection costs are not justified, and that there is an
increased risk of administrative errors.
It should be noted that certain Federal employees are subject to both the
Mandatory Guidelines and the Omnibus Transportation Employee Act of 1991, Title
V of Pub. L. 102-431, (Omnibus Act) which requires split specimens. Therefore,
the agencies must have the flexibility to collect split specimens as required
by the Omnibus Act. Since Federal agencies may also request a waiver under
section 1.1(e) of the Mandatory Guidelines and the Department has provided a
number of agencies with a waiver to permit split specimens during the past 5
years, the Department believes including an optional split specimen collection
procedure in the Mandatory Guidelines will ensure consistency among all
agencies currently using split specimens and those wanting to implement split
specimen collections. In addition, each agency should have the option of
treating its employees equally rather than treating its employees under the
Omnibus Act differently from the employees only subject to the Mandatory
Guidelines.
With regard to the perception that the results from a single specimen collection
are unreliable and not adequate to protect employee rights when compared to a
split specimen collection, the Department is confident that the results from a
single specimen collection are scientifically and legally supportable. This
belief is based on the stringent requirements that have been established by the
Mandatory Guidelines -- that is, requiring the use of rigorous chain of custody
procedures when handling and testing specimens; requiring laboratories to use
qualified and trained personnel, validated analytical testing procedures, and
extensive internal quality control and quality assurance procedures; requiring
laboratories to participate in a comprehensive certification program that
includes performance testing samples and semi-annual inspections; and using
MROs to ensure that procedures have been followed as required.
Although the split specimen procedures are designed to minimize administrative
errors, the Department acknowledges that any time procedures are modified the
risk of administrative errors increases. However, the use of a standard
specimen chain of custody form should minimize such errors and the Department,
through the inspection process, will monitor the laboratories' procedures in
processing split specimens.
The procedures for split specimens are also designed to keep the administrative
burden at a minimum. The Department believes that the paperwork for collection
sites or laboratories will not increase much since the collection sites will be
using a seven-part chain of custody form instead of a six-part form and sending
both split specimens to the laboratory at the same time and in the same
shipping container. This should minimize the additional cost and administrative
burden on both collection sites and laboratories.
One commenter believed that split specimen collections create a potential to
reverse results especially if there is a significant variation in the
analytical sensitivities of the confirmatory tests used by each of the
HHS-certified laboratories. The Department is aware of this potential and has
provided guidance to the laboratories with regard to their capability to
accurately quantitate and identify drugs at concentrations that are 40 percent
of the confirmatory test levels. The Department believes this guidance and
challenging laboratories with performance testing samples at these low
concentrations will ensure that all laboratories have essentially the same
sensitivity for each of the confirmatory tests.
Finally, one commenter requested guidance on whether the donor or agency would
be responsible for paying the costs associated with analyzing the split
specimen. The Department believes that the decision regarding financial
responsibility for testing Bottle B is one the agencies must decide.
4. Certifying Test Results
One commenter stated that the proposed revision to section 2.3(b) that discusses
"test validation" did not make it clear that a laboratory may use a certifying
scientist who is only certified to review initial drug tests which are
negative. Although this is the intent of this section and to ensure that no
confusion exists, the title of section 2.3(b) has been changed to read
"Certifying Test Results" and that section has been revised to state clearly
that a laboratory may designate a certifying scientist(s) that is only
qualified to certify results that are negative on the initial test. We note,
however, that if a certifying scientist certifies confirmatory test results,
the individual must have training and experience in all "procedures relevant to
the results that the individual certifies." This includes both initial test and
confirmatory test procedures. Changing the title of this section to read
"Certifying Test Results" should also ensure that we are referring to the
review and certification of specimen test results rather than the results
associated with "validating" an analytical procedure before it is used to test
specimens. The Department believes there was some confusion associated with the
former title of this section.
5. Security and Chain of Custody
One commenter requested that the security requirements in section 2.4(a)(1), as
proposed, be revised to allow emergency personnel access to all sections of the
laboratory without escorts. The requirements for security pertain to limiting
and documenting access under normal situations and providing escorts for
authorized visitors, maintenance, and service personnel. For real emergencies,
such as fires, it would be inappropriate to require the laboratory to provide
an escort. This section has been changed to ensure that emergency personnel
(such as firefighters) can have unescorted access similar to that authorized
for inspectors. As suggested by the commenter, it would be acceptable for the
laboratory to document the emergency and include, to the extent practicable,
dates, time of entry and exit, and purpose of entry for all emergency response
personnel. It must be noted that this exception does not apply to emergency
"service" personnel, such as manufacturers' technical representatives who are
called to repair an instrument or to conduct routine service.
6. Specimen Processing
One commenter noted that the word "standards" had been used incorrectly in
section 2.4(d), as proposed, when stating the requirements for each initial and
confirmatory batch. The Department concurs and has changed this section to
state that each initial and confirmatory batch must satisfy the quality control
requirements in sections 2.5(b) and 2.5(c), respectively, rather than using
terms such as "standards" and "controls." Additionally, the last sentence of
this section has been deleted because it is not entirely correct. Quality
control samples must be known to laboratory technicians conducting the testing
while only blind performance testing samples are unknown (i.e., the location in
the batch, drug or metabolite present, and concentration). The requirements for
laboratory blind performance testing samples and agency blind samples are
discussed in section 2.5.
7. Marijuana Initial Test Level
Many respondents concurred with lowering the initial test level for marijuana
metabolites from 100 to 50 ng/mL as proposed in section 2.4(e). However, one
commenter claimed that the lowered cutoff concentration would identify the
occasional user. The intent of Federal workplace drug testing programs is to
identify individuals who use illegal substances regardless of whether they are
regular or occasional users. Lowering the initial test level should increase
the ability to detect any use of marijuana.
Another commenter questioned the impact that might result by the lowered cutoff
concentration for those individuals who are exposed to passive inhalation
(i.e., breathing the smoke exhaled by another individual smoking marijuana
cigarettes). The Department does not believe that passive inhalation is a
reasonable defense or that significant exposure can occur through passive
inhalation to cause a urine specimen to be reported positive. A comprehensive
study of passive inhalation conducted at the National Institute on Drug Abuse's
Addiction Research Center in Baltimore (see Cone, E.J., et al., Passive
Inhalation of Marijuana Smoke: Urinalysis and Room Air Levels of
Delta-9-Tetrahydrocannabinol, Journal of Analytical Toxicology, 11: 89-96,
1987) indicates that it takes extensive exposure to extremely high
concentrations under unrealistic conditions to cause a positive result;
therefore, passive inhalation is not a reasonable explanation for a positive
result.
8. Initial and Confirmatory Tests
One commenter believed that the wording in section 2.4(e)(3), as proposed,
conflicted with the authority to conduct dilution/adulteration tests as stated
in section 2.1(c). The Department agrees that this section needs to be
clarified. A laboratory may conduct dilution/adulteration tests on all
specimens, whether they are positive or negative, and either before or after
conducting the initial test. Section 2.4(e)(3) has been changed to clarify this
policy.
Several commenters questioned the use of specimens that test negative on either
the initial test or the confirmatory test for the laboratory's internal quality
control program as proposed in sections 2.4(e)(3) and 2.4(f)(3). These
commenters were concerned that the results may have been affected by such
factors as medications that may have been taken, the health of the donors, and
possible unknown problems with confirmation, thereby, making these specimens
unsuitable as quality control samples. Several of these commenters recommended
the use of certified negative urine or, at a minimum, confirming the negative
pool by GC/MS prior to its use in a quality control program. In response to
these concerns, the Department notes that the laboratory's operation must be
consistent with good forensic laboratory practice (see section 3.20(c)) and
such practice requires a laboratory to always certify a urine pool as negative
before it is used to prepare negative samples or to prepare other quality
control samples. If pooled urine does not satisfy the criteria for
acceptability, it is discarded. Such certification of the urine will ensure the
quality of a laboratory's internal quality control program.
9. Multiple Initial Tests
Two commenters supported the use of multiple initial tests as stated in section
2.4(e)(4), as proposed, while several commenters expressed concern with
permitting the use of multiple testing. The Department believes that the use of
multiple initial tests may reduce the number of presumptive positives that are
forwarded to confirmatory testing that will not be confirmed and may allow
obtaining a valid analytical result if a specimen is untestable on one
immunoassay test.
The use of multiple initial tests has been widely used with regard to testing
for amphetamines and this policy should apply to all drugs.
In addition, there are reports that various substances, including prescription
medications, can prevent obtaining a valid initial test result when using one
immunoassay test. We believe it is appropriate to use a different immunoassay
test in order to obtain a valid initial test result before reporting the
specimen as "test not performed" and including an appropriate comment on the
specimen chain of custody form. To clarify this issue, the example given in
section 2.4(e)(4) has been changed to include the use of a second immunoassay
test for untestable specimens. It is noted that the last sentence of section
2.4(e)(4), as proposed, has been deleted since it is redundant with the
requirements as stated in the first sentence of the section.
10. 200 ng/mL Amphetamine Reporting Rule
Six commenters concurred with the proposal in sections 2.4(f)(1) and 2.4(g)(2)
that require a methamphetamine positive to contain at least 200 ng/mL of
amphetamine before reporting the result as positive. Two commenters recommended
that the 200 ng/mL rule be dropped entirely because they believed it is no
longer relevant and the emphasis should be on improving the quality of the
GC/MS confirmatory procedure. Seven commenters held similar views that the 200
ng/mL rule is too conservative and produces too many false negatives and
recommended that it be lowered to either 100 or 50 ng/mL or at least equal to
or greater than the limit of detection for amphetamine.
The Department believes that the 200 ng/mL requirement implemented as a
temporary policy since December 22, 1990, is a necessary one to prevent false
positive test results. On a special set of performance testing samples provided
to the laboratories by the program, the Department found that the requirement
adequately controlled all of the possible technical problems based on
observations of results reported by the laboratories on that set of performance
testing samples. The results indicated that a significant number of
laboratories experienced chromatographic resolution problems when
methamphetamine was present with ephedrine and 2% of the performance testing
results evidenced a methamphetamine response when challenged with high
concentrations of over-the-counter medications (e.g., ephedrine,
pseudoephedrine, or phenylpropanolamine). These results indicated that the 200
ng/mL rule was effective in preventing any false positive results and should be
continued. In addition, recent information provided by laboratories regarding
their limits of quantitation and their results on performance testing samples
that contained very low concentrations of amphetamine and methamphetamine
indicate that 200 ng/mL continues to be the lowest concentration that most of
the laboratories can reliably identify and quantitate for either
methamphetamine or amphetamine. For these reasons, the Department believes
using a lower concentration or eliminating the 200 ng/mL rule would increase
the possibility for reporting a false positive methamphetamine result.
11. Reporting Results
One commenter was concerned that substituting "certifying scientist" in section
2.4(g)(5), as proposed, for the responsible person was making the certifying
scientist responsible for the overall laboratory operations. We believe the
commenter did not understand the purpose for changing the wording in this
section. The use of "certifying scientist" in this section ensures that the
requirement is consistent with current program practice. The responsible person
continues to be responsible for the overall operation of the laboratory (see
section 2.3(a)); however, section 2.4(g)(5) allows a certifying scientist to
sign the external chain of custody form that is sent to the MRO.
12. Calibrators and Controls
One commenter raised concern with the materials used to prepare calibrators and
controls which as described in section 2.4(n)(2) only allowed calibrators and
controls to be prepared from pure drug standards. The commenter correctly
indicated that calibrators and controls were available from other sources. The
Department concurs and has revised the sentence to allow calibrators and
controls to be prepared not only from pure drug reference materials, but from
stock standard solutions obtained from other laboratories, or from commercial
manufacturers. This change clarifies that laboratories have the flexibility to
obtain "standards" used to prepare the calibrators and controls from different
sources.
13. Potential Conflicts of Interest
Several commenters supported the policies in sections 2.4(n)(6) and 2.6(b), as
proposed, that restricts the types of relationships between laboratories and
Medical Review Officers to ensure there were no conflicts of interest. There
were several comments submitted, however, stating that these requirements were
not necessary since there is no evidence that MROs have not acted in the
interest of the donor or that current arrangements have adversely affected the
ability of an MRO to monitor laboratories. The Department does not question the
dedication and integrity of its certified laboratories and the MROs in carrying
out their responsibilities and protecting the interests of the Federal agencies
and donors. Nevertheless, the Department believes the issue must be addressed.
The MRO plays an essential role in the Federal drug testing program. See
generally section 2.6 of the Mandatory Guidelines. The MRO is a licensed
physician with a knowledge of substance abuse disorders who verifies whether
the tests are positive or negative. In the case of a positive result reported
by the laboratory, the Mandatory Guidelines require that the MRO contact the
employee and personally interview the employee, i.e., in-person or by
telephone, to determine whether alternate medical explanations would explain a
positive result. See section 2.6(c). During the course of such interview and
possibly through having the specimen retested, the MRO may identify false
positive test results. In such a case, the MRO is required to contact the
Secretary so that the Department can conduct an investigation into the matter
and take whatever action is necessary to prevent such a result from occurring
in the future. See section 2.6(g). Because the MRO plays such an essential
role, the Department believes any relationship that may be construed as a
potential conflict of interest may be sufficient to undermine the integrity of
the program. Every Federal agency, employee, and job applicant must have
complete assurance that test results will be thoroughly reviewed and, if errors
are discovered, that the MRO will report the error and an appropriate
investigation and corrective action will be taken.
14. Laboratory Quality Control Requirements for Initial Tests
There were several comments submitted regarding the requirements in section
2.5(b), as proposed, for quality control samples when conducting the initial
test. The commenters believed the proposed requirements were confusing and
suggested using different terms to describe the types of quality controls that
must be included in each initial test batch. The Department concurs that the
quality control requirements in this section were confusing and they have been
revised based on the definitions in section 1.2. It should be noted the changes
to this section only clarify the requirements for quality control samples; the
actual policy has not changed from the original Mandatory Guidelines. See
section 2.5(b) of 53 FR 11979, 11984 (April 11, 1988). We have also revised the
quality control requirements for each confirmatory test batch in section 2.5(c)
using the new definitions in section 1.2 without changing the policy as
compared to the original Mandatory Guidelines. See section 2.5(c) of 53 FR
11979, 11985 (April 11, 1988).
In addition, it was noted that there was an error in the requirement that each
initial test batch must contain a minimum of 20% quality control samples. A
correction stating that 10% was the minimum amount was published in the Federal
Register on March 1, 1993.
15. Agency Blind Sample Program
A number of commenters supported reducing the requirements for agency blind
samples from 10% to 3% as indicated in section 2.5(d)(2). One commenter
suggested retaining the 10% minimum and one commenter suggested establishing a
minimum number of blind samples per quarter for organizations with a small test
population. The Department believes the reduced requirement will not have a
significant impact on the ability of an agency to evaluate its entire drug
testing program; however, there is no prohibition for an agency to use a higher
percentage or a higher number of blind samples to be submitted with donor
specimens.
The Department has also changed the requirements for the number of blind samples
to be submitted with donor specimens during the initial 90-day period of any
new contract to conform with reducing the requirements of blind samples as
provided by section 2.5(d)(2). Our experience during the past 5 years suggests
that it is not necessary to submit large numbers of blind samples to verify the
testing conducted by the certified laboratories.
16. Reanalysis Authorized
Two commenters expressed concern with the retesting policy proposed in section
2.6(e) which provided that only the MRO was authorized to order a reanalysis of
the original specimen or Bottle B from a split specimen collection. One
commenter believes the donor was authorized to request a retest of the original
specimen. It is the Department's position that if an MRO cannot verify a
positive result for whatever reason, only the MRO is authorized to request the
retest of the original specimen since the MRO is the only individual who has
all the information necessary to identify a particular specimen in a
laboratory.
Another commenter pointed out an inconsistency between the retest policy
proposed in this section and the policy proposed for testing Bottle B from a
split specimen collection as described in section 2.2(h)(6) which states that
only the donor may request through the MRO that the second specimen bottle
(Bottle B) be tested. The Department agrees that there is an inconsistency in
the proposed policies because we inadvertently referred to the Bottle B
specimen in section 2.6(e) rather than the Bottle A specimen. Section 2.6(e)
has been changed to clarify that only the MRO may request the retest of either
a single specimen or a Bottle A specimen when using a split specimen
collection. The procedures for the testing of Bottle B remain as proposed in
section 2.2(h)(6) -- that is, only the donor may request through the MRO that
Bottle B be tested.
17. Reporting Final Results to the Agency
One commenter suggested that section 2.6(h), as proposed, which clarifies the
requirement that the MRO provide written reports to the agency on positive and
negative drug test results would significantly increase the administrative
costs associated with the program and recommended that the MRO be required to
provide written reports to the agency for positive results only. The Department
disagrees. Written reports from the MRO to the agency on all specimens tested
ensures that all specimens have been tested and the results of all specimens
have been reviewed by the MRO. In addition, the Department believes that this
requirement for written reports to the agency does not prevent the MRO from
reporting several results on the same correspondence sent to the agency and,
therefore, should not significantly affect the cost associated with the MRO
review of drug testing results.
18. Certified Laboratories Notifying Private Sector Clients
Two commenters were concerned that the policy in section 3.4 did not adequately
ensure that a laboratory would inform clients if and when the laboratory did
not satisfy the certification requirements. The Department concurs that a
laboratory must inform its clients when its certification has been suspended.
Since the program began, this notification has been required and is set out in
the suspension letter that is sent to the laboratory.
However, the intent of the requirement in section 3.4 that certified
laboratories clearly inform clients when procedures followed do not conform to
the Mandatory Guidelines is not related to suspension and/or proposed
revocation actions. The purpose is to ensure that unregulated, private sector
clients are aware that the laboratory may be using procedures that are not
subject to or in accordance with the Mandatory Guidelines. The Department
believes that a certified laboratory must not use its certification to promote
itself as such if, in fact, it uses procedures that do not comply with the
Mandatory Guidelines for such clients. This section has been revised to clarify
this requirement.
19. Performance Testing Program
There were several comments submitted regarding changing the performance testing
(PT) program from a bimonthly program to a quarterly program as stated in
various sections of subpart C. One commenter disagreed with changing the
performance testing program to a quarterly program because this would prolong
the recertification process and suggested that a monthly PT program would be
more appropriate. The Department has no intention of changing the initial
certification procedures or to change the procedures when a laboratory has been
suspended and must successfully analyze performance testing samples prior to
having the suspension lifted. In addition, the Department believes a monthly PT
program does not allow sufficient time for a laboratory to receive its results
on a set of PT samples, analyze its performance, and initiate appropriate
corrective action before the next cycle of PT samples.
One commenter was concerned that adopting a quarterly PT program without
changing the criteria for determining acceptable performance, as set out in
section 3.19, would increase the period for evaluating a laboratory's
performance to 9 months. The Department concurs that the criteria for
determining acceptable performance, that is, performance on 3 consecutive
quarterly PT cycles, would unduly lengthen the time before corrective action
may be taken. Since the total number of PT samples in 2 cycles of the quarterly
PT program will be essentially the same as those for 3 cycles of the bimonthly
PT program, it is appropriate to establish acceptable performance criteria
based on performance over 2 consecutive cycles of quarterly PT samples. All
criteria in section 3.19 that pertain to evaluating the performance of
certified laboratories have been changed to evaluate acceptable performance
over 2 consecutive cycles rather than over 3 consecutive cycles, which retains
the 6-month evaluation period.
One commenter agreed with the change in section 3.19(b)(4), as proposed, that
would allow a certified laboratory to have one quantitative result greater than
50% from the target value without requiring program action against the
laboratory. However, the commenter is concerned that the cause for the error
may not be investigated since program action is not taken against the
laboratory. The Department did not intend that this change would prevent any
investigation into the cause for the error or that the laboratory would not be
required by the Department to make a concerted effort to determine the cause
for the error and to take appropriate corrective action. One commenter believes
that the overall costs for the certification program may be decreased without
compromising the high quality of the program by increasing the PT challenges to
a monthly program and decreasing the maintenance inspections to once a year.
The Department disagrees with this proposal because it is important to inspect
laboratories at least every six months to ensure that the laboratory has
continued to satisfy the requirements of the Mandatory Guidelines and for the
inspectors to review the results reported for the PT samples. If corrective
action is necessary, it will be more timely than if inspections were on a
yearly basis. In addition, the existence of a significant problem over a long
period of time would possibly jeopardize the results of many more personnel
specimens.
20. Corrective Action by Certified Laboratories
Several commenters expressed concern that section 3.12(c), as proposed, would
give the Secretary the authority to review all results and activities
associated with a laboratory's testing of specimens for private sector,
unregulated clients. This was not the intent and the section has been changed
to indicate that the Secretary has authority to review results for specimens
collected for private sector clients that were tested by the certified
laboratory under the Mandatory Guidelines to the extent necessary to ensure the
full reliability of drug testing for Federal agencies.
21. Recertification
One commenter was concerned with the policy contained in section 3.16, as
proposed, because the commenter believed the procedure to regain certification
after the laboratory's certification has been revoked would be prolonged given
that the maintenance PT program has been reduced to a quarterly program. The
commenter misunderstood that provision. The Department has not changed the
initial certification procedure (section 3.16) under which a laboratory that
had its certification revoked must proceed to regain certification. Thus, such
a laboratory will proceed as in the past and must satisfactorily perform in
each phase of the initial certification process. However, the first sentence of
section 3.16 has been changed to indicate that the recertification policy
applies only when a laboratory has its certification revoked.
22. Inspection Performance
One commenter was concerned that the meaning of the phrase "consistent with good
forensic laboratory practice" in section 3.20(c), as proposed, was too
subjective. The commenter believes that each inspection team interprets
laboratory's procedures differently, thereby, what is acceptable during one
inspection may be unacceptable during the next inspection. We do not concur
with this assessment of the inspection process. Although there is some inherent
subjectivity in the inspection process when applying certain criteria under the
Mandatory Guidelines, the inspectors are provided clear guidance on what is to
be inspected and what is acceptable and unacceptable. The Department requires
trained, qualified inspectors to use a comprehensive checklist consisting of
some 300 questions to evaluate a laboratory's procedures. They are asked to
respond "yes" or "no" to the questions and then provide comments if the answer
is unacceptable. This checklist ensures that each inspector is reviewing
essentially all of the same laboratory documents and results. The inspection
reports are reviewed by the Department to ensure that program requirements and
policies are applied consistently among all laboratories. In addition, it is
the responsibility of each laboratory to review the Mandatory Guidelines, to be
aware of what is to be inspected by reviewing the checklist and other program
documents, to correct deficiencies, and to use good forensic laboratory
practice in its testing program.
One commenter suggested that the word "all" be deleted from the second sentence
in section 3.20(c), as proposed, because a laboratory is not required to
correct "all" deficiencies identified by the inspectors. We concur with the
comment and have deleted the word "all." The Department's policy has always
been to include minor deficiencies or concerns in the critique developed from
the inspection reports and give the laboratory the option to take whatever
additional corrective action it deems appropriate for these minor deficiencies
or concerns.
23. Procedures for Review of Suspension or Proposed Revocation of a Certified
Laboratory
One commenter suggests that the definition of appellant in section 4.2, as
proposed, is unclear and believes that the review procedures only apply when
there is a proposed revocation. The Department disagrees with this position.
The Department believes that principles of fairness necessitate allowing
laboratories to seek internal reviews not only of proposed revocations but also
internal reviews of immediate suspensions.
24. Other Minor Changes
In addition to the changes discussed above, there were several minor changes
made in other sections. The acronym "MRO" has been added to the definition for
Medical Review Officer in section 1.2. Since the original Guidelines were
published, the "MRO" acronym has become a common and accepted way to refer to a
physician performing this function. We have replaced "Medical Review Officer"
with "MRO" throughout the Guidelines.
Section 2.5(d)(4) was changed to clarify that an agency shall investigate any
unsatisfactory blind performance testing results and submit its findings to HHS
rather than HHS conducting the initial investigation. The Department believes
the agency must gather all pertinent information and investigate the reason
before HHS is contacted to continue the investigation and to ensure that the
laboratory has taken corrective action.
Section 2.6(c) has been simplified to require the MRO to send results only to
the designated person in the agency rather than to both agency's Employee
Assistance Program and to the agency's management official. The Department
believes that the agency should have the discretion to determine who should
receive results.
Section 3.3 was clarified to read that a laboratory must satisfy all pertinent
provisions of the Guidelines in order to maintain certification while the
original requirement only addressed satisfying the provisions in order to
qualify for certification.
Section 3.15(b) was revised to conform with the review procedure in new subpart
D which allows laboratories the opportunity for an informal review of a program
action within 30 days of the date the laboratory received the notice, or if
seeking an expedited review, within 3 days of the date the laboratory received
the notice.
Two commenters noted that section 3.18(b) referred to a subset of PT samples as
"directed specimens" rather than as "retest samples" which is current program
terminology. We concur with the comment submitted and have revised the section
to refer to these PT samples as "retest samples."
Other appropriate minor editorial changes have been made for clarity and
consistency.
Information Collection Requirements
Any comments related to the Paperwork Reduction Act of 1980 may be sent to the
HHS Desk Officer, Office of Information and Regulatory Affairs, Office of
Management and Budget, Room 3001, New Executive Office Building, Washington,
D.C. 20503. Information collection and recordkeeping requirements which would
be imposed on laboratories engaged in urine drug testing for Federal agencies
concern quality assurance and quality control; security and chain of custody;
documentation; reports; performance testing; and inspections as set out in
sections 3.7, 3.8, 3.10, 3.11, 3.17, and 3.20. To facilitate ease of use and
uniform reporting, a specimen chain of custody form has been developed as
referenced in sections 1.2, 2.2(c), and 2.2(f).
The information collection and recordkeeping requirements contained in these
Mandatory Guidelines have been submitted to the Office of Management and Budget
for review under section 3504(h) of the Paperwork Reduction Act of 1980.

Subpart A - General
Section 1.1 Applicability.
(a) These mandatory guidelines apply to:
(1) Executive Agencies as defined in 5 U.S.C. 105;
(2) The Uniformed Services, as defined in 5 U.S.C. 2101(3) (but excluding the
Armed Forces as defined in 5 U.S.C. 2101(2));
(3) And any other employing unit or authority of the Federal Government except
the United States Postal Service, the Postal Rate Commission, and employing
units or authorities in the Judicial and Legislative Branches.
(b) Subpart C of these Guidelines (which establishes laboratory certification
standards) applies to any laboratory which has or seeks certification to
perform urine drug testing for Federal agencies under a drug testing program
conducted under E.O. 12564. Only laboratories certified under these standards
are authorized to perform urine drug testing for Federal agencies.
(c) The Intelligence Community, as defined by Executive Order No. 12333, shall
be subject to these Guidelines only to the extent agreed to by the head of the
affected agency.
(d) These Guidelines do not apply to drug testing conducted under legal
authority other than E.O. 12564, including testing of persons in the criminal
justice system, such as arrestees, detainees, probationers, incarcerated
persons, or parolees.
(e) Agencies may not deviate from the provisions of these Guidelines without the
written approval of the Secretary. In requesting approval for a deviation, an
agency must petition the Secretary in writing and describe the specific
provision or provisions for which a deviation is sought and the rationale
therefor. The Secretary may approve the request upon a finding of good cause as
determined by the Secretary.
(f) Agencies shall purchase drug testing services only from laboratories
certified by HHS or an HHS-recognized certification program in accordance with
these Guidelines.
Section 1.2 Definitions.
For purposes of these Guidelines the following definitions are adopted: Aliquot
A fractional part of a specimen used for testing. It is taken as a sample
representing the whole specimen.
Calibrator A solution of known concentration used to calibrate a
measurement procedure or to compare the response obtained with the response of
a test specimen/sample. The concentration of the analyte of interest in the
calibrator is known within limits ascertained during its preparation.
Calibrators may be used to establish a calibration curve over a range of
interest. Certifying Scientist An individual with at least a bachelor's degree
in the chemical or biological sciences or medical technology or equivalent who
reviews all pertinent data and quality control results. The individual shall
have training and experience in the theory and practice of all methods and
procedures used in the laboratory, including a thorough understanding of chain
of custody procedures, quality control practices, and analytical procedures
relevant to the results that the individual certifies. Relevant training and
experience shall also include the review, interpretation, and reporting of test
results; maintenance of chain of custody; and proper remedial action to be
taken in response to test systems being out of control-limits or detecting
aberrant test or quality control results.
Chain of Custody Procedures to account for the integrity of each urine
specimen by tracking its handling and storage from point of specimen collection
to final disposition of the specimen. These procedures shall require that an
Office of Management and Budget (OMB) approved specimen chain of custody form
be used from time of collection to receipt by the laboratory and that upon
receipt by the laboratory an appropriate laboratory chain of custody form(s)
account for the specimens and samples within the laboratory. Chain of custody
forms shall, at a minimum, include an entry documenting date and purpose each
time a specimen or sample is handled or transferred and identifying every
individual in the chain of custody. Collection Site A place designated by the
agency where individuals present themselves for the purpose of providing a
specimen of their urine to be analyzed for the presence of drugs. Collection
Site Person A person who instructs and assists individuals at a collection site
and who receives and makes an initial examination of the urine specimen
provided by those individuals. A collection site person shall have successfully
completed training to carry out this function.
Confirmatory Test A second analytical procedure to identify the presence
of a specific drug or metabolite which is independent of the initial test and
which uses a different technique and chemical principle from that of the
initial test in order to ensure reliability and accuracy. (At this time gas
chromatography/mass spectrometry (GC/MS) is the only authorized confirmation
method for cocaine, marijuana, opiates, amphetamines, and phencyclidine.)
Control A sample used to monitor the status of an analysis to maintain its
performance within desired limits.
Donor The individual from whom a urine specimen is collected. Initial
Test (also known as Screening Test) An immunoassay test to eliminate "negative"
urine specimens from further consideration and to identify the presumptively
positive specimens that require confirmation or further testing.
Laboratory Chain of Custody Form The form(s) used by the testing
laboratory to document the security of the specimen and all aliquots of the
specimens during testing and storage by the laboratory. The form, which may
account for an entire laboratory test batch, shall include the names and
signatures of all individuals who accessed the specimens or aliquots and the
date and purpose of the access.
Medical Review Officer (MRO) A licensed physician responsible for
receiving laboratory results generated by an agency's drug testing program who
has knowledge of substance abuse disorders and has appropriate medical training
to interpret and evaluate an individual's positive test result together with
his or her medical history and any other relevant biomedical information.
Quality Control Sample A sample used to evaluate whether or not the analytical
procedure is operating within predefined tolerance limits. Calibrators,
controls, negative urine samples, and blind samples are collectively referred
to as "quality control samples" and each as a "sample."
Reason to Believe Reason to believe that a particular individual may
alter or substitute the urine specimen as provided in section 4(c) of E.O.
12564. Sample A representative portion of a urine specimen or quality control
sample used for testing.
Secretary The Secretary of Health and Human Services or the Secretary's
designee. The Secretary's designee may be a contractor or other recognized
organization which acts on behalf of the Secretary in implementing these
Guidelines.
Specimen The portion of urine that is collected from a donor.
Specimen Chain of Custody Form An OMB approved form used to document the
security of the specimen from time of collection until receipt by the
laboratory. This form, at a minimum, shall include specimen identifying
information, date and location of collection, name and signature of collector,
name of testing laboratory, and the names and signatures of all individuals who
had custody of the specimen from time of collection until the specimen was
prepared for shipment to the laboratory.
Standard A reference material of known purity or a solution containing a
reference material at a known concentration.
Section 1.3 Future Revisions.
In order to ensure the full reliability and accuracy of drug assays, the
accurate reporting of test results, and the integrity and efficacy of Federal
drug testing programs, the Secretary may make changes to these Guidelines to
reflect improvements in the available science and technology. These changes
will be published in final as a notice in the Federal Register.
Subpart B - Scientific and Technical Requirements
Section 2.1 The Drugs.
(a) The President's Executive Order 12564 defines "illegal drugs" as those
included in Schedule I or II of the Controlled Substances Act (CSA), but not
when used pursuant to a valid prescription or when used as otherwise authorized
by law. Hundreds of drugs are covered under Schedule I and II and while it is
not feasible to test routinely for all of them, Federal drug testing programs
shall test for drugs as follows:
(1) Federal agency applicant and random drug testing programs shall at a minimum
test for marijuana and cocaine;
(2) Federal agency applicant and random drug testing programs are also
authorized to test for opiates, amphetamines, and phencyclidine; and
(3) When conducting reasonable suspicion, accident, or unsafe practice testing,
a Federal agency may test for any drug listed in Schedule I or II of the CSA.
(b) Any agency covered by these guidelines shall petition the Secretary in
writing for approval to include in its testing protocols any drugs (or classes
of drugs) not listed for Federal agency testing in paragraph (a) of this
section. Such approval shall be limited to the use of the appropriate science
and technology and shall not otherwise limit agency discretion to test for any
drugs covered under Schedule I or II of the CSA.
(c) Urine specimens collected pursuant to Executive Order 12564, Pub. L. 100-71,
and these Guidelines shall be used only to test for those drugs included in
agency drug-free workplace plans and may not be used to conduct any other
analysis or test unless otherwise authorized by law except if additional
testing is required to determine the validity of the specimen. Urine that tests
negative by initial or confirmatory testing may, however, be pooled for use in
the laboratory's internal quality control program.
(d) These Guidelines are not intended to limit any agency which is specifically
authorized by law to include additional categories of drugs in the drug testing
of its own employees or employees in its regulated industries.
Section 2.2 Specimen Collection Procedures.
(a) Designation of Collection Site. Each agency drug testing program
shall have one or more designated collection sites which have all necessary
personnel, materials, equipment, facilities, and supervision to provide for the
collection, security, temporary storage, and shipping or transportation of
urine specimens to a certified drug testing laboratory.
(b) Security. Procedures shall provide for the designated collection site
to be secure. If a collection site facility is dedicated solely to urine
collection, it shall be secure at all times. If a facility cannot be dedicated
solely to drug testing, the portion of the facility used for testing shall be
secured during drug testing.
(c) Chain of Custody. Chain of custody standardized forms shall be
properly executed by authorized collection site personnel upon receipt of
specimens. Handling and transportation of urine specimens from one authorized
individual or place to another shall always be accomplished through chain of
custody procedures. Every effort shall be made to minimize the number of
persons handling specimens.
(d) Access to Authorized Personnel Only. No unauthorized personnel shall
be permitted in any part of the designated collection site when urine specimens
are collected or stored.
(e) Privacy. Procedures for collecting urine specimens shall allow
individual privacy unless there is reason to believe that a particular donor
may alter or substitute the specimen to be provided.
(f) Integrity and Identity of Specimen. Agencies shall take precautions
to ensure that a urine specimen not be adulterated or diluted during the
collection procedure and that information on the urine bottle and on the
specimen chain of custody form can identify the donor from whom the specimen
was collected. The following minimum precautions shall be taken to ensure that
unadulterated specimens are obtained and correctly identified:
(1) To deter the dilution of specimens at the collection site, toilet bluing
agents shall be placed in toilet tanks wherever possible, so the reservoir of
water in the toilet bowl always remains blue. There shall be no other source of
water (e.g., no shower or sink) in the enclosure where urination occurs.
(2) When a donor arrives at the collection site, the collection site person
shall request the donor to present photo identification. If the donor does not
have proper photo identification, the collection site person shall contact the
supervisor of the donor, the coordinator of the drug testing program, or any
other agency official who can positively identify the donor. If the donor's
identity cannot be established, the collection site person shall not proceed
with the collection.
(3) If the donor fails to arrive at the assigned time, the collection site
person shall contact the appropriate authority to obtain guidance on the action
to be taken.
(4) The collection site person shall ask the donor to remove any unnecessary
outer garments such as a coat or jacket that might conceal items or substances
that could be used to tamper with or adulterate the donor's urine specimen. The
collection site person shall ensure that all personal belongings such as a
purse or briefcase remain with the outer garments. The donor may retain his or
her wallet.
(5) The donor shall be instructed to wash and dry his or her hands prior to
urination.
(6) After washing hands, the donor shall remain in the presence of the
collection site person and shall not have access to any water fountain, faucet,
soap dispenser, cleaning agent, or any other materials which could be used to
adulterate the specimen.
(7) The collection site person shall give the donor a clean specimen bottle or
specimen container. The donor may provide his/her specimen in the privacy of a
stall or otherwise partitioned area that allows for individual privacy.
(8) The collection site person shall note any unusual behavior or appearance on
the specimen chain of custody form.
(9) In the exceptional event that an agency-designated collection site is not
accessible and there is an immediate requirement for specimen collection (e.g.,
an accident investigation), a public rest room may be used according to the
following procedures: A person of the same gender as the donor shall accompany
the donor into the public rest room which shall be made secure during the
collection procedure. If possible, a toilet bluing agent shall be placed in the
bowl and any accessible toilet tank. The collection site person shall remain in
the rest room, but outside the stall, until the specimen is collected. If no
bluing agent is available to deter specimen dilution, the collection site
person shall instruct the donor not to flush the toilet until the specimen is
delivered to the collection site person. After the collection site person has
possession of the specimen, the donor will be instructed to flush the toilet
and to participate with the collection site person in completing the chain of
custody procedures.
(10) Upon receiving the specimen from the donor, the collection site person
shall determine the volume of urine in the specimen bottle/container.
(i) If the volume is greater than 30 milliliters (mL), the collection site
person will proceed with step (11) below.
(ii) If the volume is less than 30 mL and the temperature is within the
acceptable range specified in step (13) below, the specimen is discarded and a
second specimen shall be collected. The donor may be given a reasonable amount
of liquid to drink for this purpose (e.g., an 8 oz glass of water every 30 min,
but not to exceed a maximum of 24 oz). If the donor fails for any reason to
provide 30 mL of urine for the second specimen collected, the collection site
person shall contact the appropriate authority to obtain guidance on the action
to be taken.
(iii) If the volume is less than 30 mL and the temperature is outside the
acceptable range specified in step (13) below, a second specimen shall be
collected using the procedure specified in step (13) below.
(11) After the specimen has been provided and submitted to the collection site
person, the donor shall be allowed to wash his or her hands.
(12) Immediately after the specimen is collected, the collection site person
shall measure only the temperature of the specimen. The temperature measuring
device used must accurately reflect the temperature of the specimen and not
contaminate the specimen. The time from urination to temperature measurement is
critical and in no case shall exceed 4 minutes.
(13) If the temperature of the specimen is outside the range of 32 -38 C/90 -100
F, that is a reason to believe that the donor may have altered or substituted
the specimen, and another specimen shall be collected under direct observation
of a person of the same gender and both specimens shall be forwarded to the
laboratory for testing. The agency shall select the observer if there is no
collection site person of the same gender available. A donor may volunteer to
have his or her oral temperature taken to provide evidence to counter the
reason to believe the donor may have altered or substituted the specimen caused
by the specimen's temperature falling outside the prescribed range.
(14) Immediately after the specimen is collected, the collection site person
shall also inspect the specimen to determine its color and look for any signs
of contaminants. Any unusual findings shall be noted on the specimen chain of
custody form.
(15) All specimens suspected of being adulterated or diluted shall be forwarded
to the laboratory for testing.
(16) When there is any reason to believe that a donor may have altered or
substituted the specimen to be provided, another specimen shall be obtained as
soon as possible under the direct observation of a person of the same gender
and both specimens shall be forwarded to the laboratory for testing. The agency
shall select the observer if there is no collection site person of the same
gender available.
(17) Both the donor and the collection site person shall keep the specimen
bottle/container in view at all times prior to its being sealed and labeled. If
the specimen is transferred from a specimen container to a specimen bottle, the
collection site person shall request the donor to observe the transfer of the
specimen and the placement of the tamper-evident seal/tape on the bottle. The
tamper-evident seal may be in the form of evidence tape, a self- sealing bottle
cap with both a tamper-evident seal and unique coding, cap and bottle systems
that can only be sealed one time, or any other system that ensures any
tampering with the specimen will be evident to laboratory personnel during the
accessioning process.
(18) The collection site person and the donor shall be present at the same time
during procedures outlined in paragraphs (f)(19)-(f)(22) of this section.
(19) The collection site person shall place securely on the specimen bottle an
identification label which contains the date, the donor's specimen number, and
any other identifying information provided or required by the agency.
(20) The donor shall initial the identification label on the specimen bottle for
the purpose of certifying that it is the specimen collected from him or her.
(21) The collection site person shall enter on the specimen chain of custody
form all information identifying the specimen.
(22) The donor shall be asked to read and sign a statement on the specimen chain
of custody form certifying that the specimen identified as having been
collected from him or her is in fact that specimen he or she provided.
(23) Based on a reason to believe that the donor may alter or substitute the
specimen to be provided, a higher level supervisor shall review and concur in
advance with any decision by a collection site person to obtain a specimen
under direct observation. The person directly observing the specimen collection
shall be of the same gender. The agency shall select the observer if there is
no collection site person of the same gender available.
(24) The collection site person shall complete the specimen chain of custody
form.
(25) The urine specimen and specimen chain of custody form are now ready for
shipment. If the specimen is not immediately prepared for shipment, it shall be
appropriately safeguarded during temporary storage.
(26) While any part of the above chain of custody procedures is being performed,
it is essential that the urine specimen and custody documents be under the
control of the involved collection site person. If the involved collection site
person leaves his or her work station momentarily, the urine specimen and
specimen chain of custody form shall be taken with him or her or shall be
secured. After the collection site person returns to the work station, the
custody process will continue. If the collection site person is leaving for an
extended period of time, the specimen shall be packaged for mailing before he
or she leaves the site.
(g) Collection Control. To the maximum extent possible, collection site
personnel shall keep the donor's specimen bottle within sight both before and
after the donor has urinated. After the specimen is collected, it shall be
properly sealed and labeled. A specimen chain of custody form shall be used for
maintaining control and accountability of each specimen. The date and purpose
shall be documented on a specimen chain of custody form each time a specimen is
handled or transferred and every individual in the chain shall be identified.
Every effort shall be made to minimize the number of persons handling
specimens.
(h) Split Specimens. An agency may, but is not required to, use a split
specimen method of collection. If the urine specimen is split into two specimen
bottles (hereinafter referred to as Bottle A and Bottle B) the following
procedure shall be used:
(1) The donor shall urinate into either a specimen bottle or specimen container.
The collection site person, in the presence of the donor, after determining
specimen temperature, pours the urine into two specimen bottles that are
labeled Bottle A and Bottle B or, if Bottle A was used to collect the specimen,
pours an appropriate amount into Bottle B. A minimum of 45 mL of urine is
required when using a split specimen procedure, i.e., 30 mL for Bottle A and 15
mL for Bottle B.
(2) The Bottle A specimen, containing a minimum of 30 mL of urine, is to be used
for the drug test. If there is no additional urine available for the second
specimen bottle (Bottle B), the first specimen bottle (Bottle A) shall
nevertheless be processed for testing.
(3) A minimum of 15 mL of urine shall be poured into the second specimen bottle
(Bottle B).
(4) All requirements of this part shall be followed with respect to Bottle A and
Bottle B, including the requirements that a copy of the chain of custody form
accompany each bottle processed under split sample procedures.
(5) The collection site shall send the split specimens (Bottle A and Bottle B)
at the same time to the laboratory that will be testing the Bottle A specimen.
(6) If the test of the first specimen bottle (Bottle A) is verified positive by
the MRO, the MRO shall report the result to the agency. Only the donor may
request through the MRO that the second specimen bottle (Bottle B) be tested in
an HHS-certified laboratory for presence of the drug(s) for which a positive
result was obtained in the test of the first specimen bottle (Bottle A). The
MRO shall honor such a request if it is made within 72 hours of the donor's
having received notice that he or she tested positive. The result of this test
is transmitted to the MRO without regard to the cutoff levels used to test the
first specimen bottle (Bottle A).
(7) Any action taken by a Federal agency as a result of an MRO verified positive
drug test (e.g., removal from performing a safety-sensitive function) may
proceed whether Bottle B is or is not tested.
(8) If the result of the test on the second specimen bottle (Bottle B) fails to
reconfirm the result reported for Bottle A, the MRO shall void the test result
for Bottle A and the donor shall re-enter the group subject to random testing
as if the test had not been conducted. The MRO shall notify the Federal agency
when a failed to reconfirm has occurred and the agency shall contact the
Secretary. The Secretary will investigate the failed to reconfirm result and
attempt to determine the reason for the inconsistent results between Bottle A
and Bottle B. HHS will report its findings to the agency including
recommendations and/or actions taken to prevent the recurrence of the failed to
reconfirm result.
(i) Transportation to Laboratory. Collection site personnel shall arrange
to ship the collected specimens to the drug testing laboratory. The specimens
shall be placed in containers designed to minimize the possibility of damage
during shipment, for example, specimen boxes or padded mailers; and those
containers shall be securely sealed to eliminate the possibility of undetected
tampering. The collection site personnel shall ensure that the specimen chain
of custody form is enclosed within each container sealed for shipment to the
drug testing laboratory. Since specimens are sealed in packages that would
indicate any tampering during transit to the laboratory and couriers, express
carriers, and postal service personnel do not have access to the chain of
custody forms, there is no requirement that such personnel document chain of
custody for the package during transit.
Section 2.3 Laboratory Personnel.
(a) Day-to-Day Management.
(1) The laboratory shall have a responsible person (RP) to assume professional,
organizational, educational, and administrative responsibility for the

Section 2.4 Laboratory Analysis Procedures.
(a) Security and Chain of Custody. (1) Drug testing laboratories shall be
secure at all times. They shall have in place sufficient security measures to
control access to the premises and to ensure that no unauthorized personnel
handle specimens or gain access to the laboratory processes or to areas where
records are stored. Access to these secured areas shall be limited to
specifically authorized individuals whose authorization is documented. With the
exception of personnel authorized to conduct inspections on behalf of Federal
agencies for which the laboratory is engaged in urine testing or on behalf of
the Secretary or emergency personnel (e.g., firefighters and medical rescue
teams), all authorized visitors and maintenance and service personnel shall be
escorted at all times. The laboratory shall maintain a record that documents
the dates, time of entry and exit, and purpose of entry of authorized visitors,
maintenance, and service personnel accessing secured areas.
(2) Laboratories shall use chain of custody procedures to maintain control and
accountability of specimens from receipt through completion of testing,
reporting of results, during storage, and continuing until final disposition of
specimens. The date and purpose shall be documented on an appropriate chain of
custody form each time a specimen is handled or transferred, and every
individual in the chain shall be identified. Accordingly, authorized
technicians shall be responsible for each urine specimen or aliquot in their
possession and shall sign and complete chain of custody forms for those
specimens or aliquots as they are received.
(b) Receiving. (1) When a shipment of specimens is received, laboratory
personnel shall inspect each package for evidence of possible tampering and
compare information on specimen bottles within each package to the information
on the accompanying chain of custody forms. Any direct evidence of tampering or
discrepancies in the information on specimen bottles and the specimen chain of
custody forms attached to the shipment shall be immediately reported to the
agency and shall be noted on the specimen chain of custody forms which shall
accompany the specimens while they are in the laboratory's possession.
(2) Specimen bottles will normally be retained within the laboratory's accession
area until all analyses have been completed. Aliquots and laboratory chain of
custody forms shall be used by laboratory personnel for conducting initial and
confirmatory tests while the original specimen and specimen chain of custody
form remain in secure storage.
(c) Short-Term Refrigerated Storage. Specimens that do not receive an
initial test within 7 days of arrival at the laboratory shall be placed in
secure refrigeration units. Temperatures shall not exceed 6 C. Emergency power
equipment shall be available in case of prolonged power failure.
(d) Specimen Processing. Laboratory facilities for urine drug testing
will normally process specimens by grouping them into batches. The number of
specimens in each batch may vary significantly depending on the size of the
laboratory and its workload. When conducting either initial or confirmatory
tests, every batch shall satisfy the quality control requirements in sections
2.5 (b) and (c), respectively.
(e) Initial Test. (1) The initial test shall use an immunoassay which
meets the requirements of the Food and Drug Administration for commercial
distribution. The following initial cutoff levels shall be used when screening
specimens to determine whether they are negative for these five drugs or
classes of drugs:
Initial Test Level (ng/mL)
Marijuana metabolites............ 50
Cocaine metabolites............... 300
Opiate metabolites................. 300*
Phencyclidine........................ 25
Amphetamines...................... 1,000
* 25 ng/mL if immunoassay specific for free morphine.
(2) These test levels are subject to change by the Department of Health and
Human Services as advances in technology or other considerations warrant
identification of these substances at other concentrations. The agency
requesting the authorization to include other drugs shall submit to the
Secretary in writing the agency's proposed initial test methods, testing
levels, and proposed performance test program.
(3) Specimens that test negative on all initial immunoassay tests will be
reported negative. No further testing of these negative specimens for drugs is
permitted and the specimens shall either be discarded or pooled for use in the
laboratory's internal quality control program.
(4) Multiple initial tests (also known as rescreening) for the same drug
