Description of Federal Register Publication or Historical Event
10/31/88
Clinical Laboratory Improvement Amendments (CLIA) of 1988 was enacted.
Waived tests were defined as simple laboratory examinations and
procedures
which, as
determined by the Secretary, have an
insignificant
risk of an
erroneous
result, including those
which--
(1)
have been approved by the Food and Drug Administration (FDA) for home use;
(2) employ methodologies that are so simple and accurate as to render
the
l
ikelihood of erroneous results negligible
;
or
(3) the Secretary has determined pose no reasonable risk of harm to the patient if
the test is performed incorrectly.
In addition, the law specified that waived tests are exempt from the CLIA health and safety
standards, including personnel, patient test management, quality control, proficiency testing,
quality assurance and routine inspections requirements.
2/28/92
Regulations (final rule with comment) were published listing eight types of tests or
examinations that met
the
statutory waiver criteria:
(1) dipstick or tablet reagent urinalysis (non-automated) for
bilirubin,
glucose, hemoglobin,
ketone, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen;
(2) fecal occult
blood;
(3) ovulation tests--visual color comparison tests for human luteinizing hormone;
(4) urine pregnancy tests--visual color comparison
tests;
(5) erythrocyte sedimentation
rate--non-automated;
(6) hemoglobin--copper sulfate--non-automated;
(7) blood glucose by glucose monitoring devices cleared by the FDA specifically for home
use; and
(8) spun microhematocrit.
1/19/93
A final rule was published adding to the list of waived tests: hemoglobin by single analyte
instruments with self-contained or component features to perform specimen/reagent
interaction, providing direct measurement and
readout.
2/18/93
Approximately 1,100 of the comments received to the 2/28/92 regulations concerned the
determination of waived test status, specifically the subjectiveness of the criteria for waiver and
the failure of tests to be granted waiver. The Centers for Disease Control and Prevention (CDC)
sought advice from the CLIAC and on 2/17-18/93. CLIAC recommended that CDC clarify the
criteria and process for waiver and establish a moratorium on considering tests for waiver
approval until the criteria were better defined. CDC established the moratorium, as
recommended, while developing guidelines and a proposed rule to revise the CLIA requirements
for waiver approvals. CDC used the determination of "simple" and "not prone to error" as a
mechanism to meet the statutory requirement that waived tests "have an
insignificant
risk of an
erroneous result" and required waived testing to be capable of performing accurately under all
testing conditions and in all test settings.

12/19/94
The waiver moratorium was lifted, and an interim waiver review process was established by
CDC. CDC notified manufacturers of moderate complexity test systems that it would consider
any moderate complexity test system that met the statutory waiver criteria and for which
the
manufacturer or producer applied for waiver in accordance with the draft guidelines
containing waiver criteria a process for reviewing waiver requests.
9/13/95
A proposed rule was published
clarifying
the
statutory
criteria for determining which tests
could be waived and to provide for automatic
waiver of FDA-
approved home use tests. The
rule also proposed that all previously waived tests be reevaluated using the clarifications to the
waiver criteria in the regulation.
11/21/97
Congress enacted the Food and Drug Administration Modernization Act of
1997 (FDAMA)
revising the CLIA law to make it clear that tests approved by the FDA for home
use
automatically qualify for CLIA waiver. In addition, Congress added "by the
user"
to the
waiver provision related to
simplicity
and accuracy of methodologies, i.e., "employ
methodologies that are so simple and accurate as to render the likelihood of erroneous results
by the user negligible." (emphasis added). The waiver section of the CLIA statute now
reads: Waived tests "are laboratory examinations and procedures that have been approved by
the Food and Drug Administration for home use or that,
as
determined by the Secretary, are
simple laboratory examinations and procedures that have an insignificant risk of an erroneous
result, including those
that-
(A) employ methodologies that are so simple and accurate as to render the
likelihood of erroneous results by the user
negligible,
or
(B) the Secretary has determined pose no unreasonable risk of harm to the patient if
performed
incorrectly."
According to the legislative history from House Report 105-310 to associated bill H.R. 1411
under section 21, "Modernization of regulation," the intent of the "by the user"
clarifying
language was to focus the waiver criteria on
verifying
test
performance by the user and
eliminating
the potential for operator error in performing the test. The history also stated that,
without this clarification, interpretations
of "erroneous
result" and "accurate" could include the
inherent
clinical
sensitivity and specificity of a test system, which would be inappropriate since
those parameters were under the purview of the FDA. The history concluded by stating that
this change was intended only to
specify
the focus of
the
criterion and
"
not meant in any way to
change the acceptable level of user
error."
5/12/98
A citizen petition was filed by the Partners for Public Health and Government requesting
CDC and the Health Care Financing Administration (HCFA) – now the Centers for
Medicare and Medicaid Services (CMS) - to enter into negotiated rulemaking to develop
waiver regulations.
2/27/99
An interagency agreement was signed by CDC, HCFA, and FDA, transferring
the
responsibility
for categorizing the complexity of commercially marketed laboratory tests and evaluating requests
for waiver from CDC to FDA.
12/30/99
A Federal Register notice announced the transfer of responsibility for the categorization
(including waiver determinations) of commercially marketed in vitro diagnostic (IVD) tests under
CLIA’88 from CDC to the FDA. The transfer of test categorization was completed January 2000
and the transfer of the
responsibility
for waiver determinations was completed February 2000.

8/14-15/00
FDA held a
public
workshop to obtain comments on the criteria and process used to determine
whether a test could be waived. Presentations
were
made by 29
individuals
representing
government, industry, professional
laboratory
organizations, and academic institutions and some
provided written comments.
1/23/01
FDA posted draft guidance for waiver, "Guidance for
Clinical
Laboratory Improvement
Amendments of 1988 (CLIA) Criteria for Waiver; Draft Guidance for Industry and
FDA," on
its website and sent a copy
to CDC for distribution at the upcoming CLIAC meeting.
09/07/05
FDA published a notice announcing the availability of the updated draft guidance entitled
“Recommendations for Clinical Laboratory Improvement Amendments of 1988 (CLIA) Waiver
Applications” to recommend an approach for submission of waiver applications by
manufacturers. This draft guidance replaced the previous draft guidance entitled “Guidance for
Clinical Laboratory Improvement Amendments of 1988 (CLIA) Criteria for Waiver.
01/30/08
FDA published a notice announcing the availability of the final guidance entitled
“Recommendations for Clinical Laboratory Improvement Amendments of 1988 (CLIA) Waiver
Applications for Manufacturers of In Vitro Diagnostic Devices.” The guidance described
recommendations for device manufacturers seeking to submit applications to FDA for waiver
approval.
