Administrative Procedures for CLIA Categorization - Guidance for Industry and Food and Drug Administration Staff
On February 28, 1992, the Department of Health and Human Services (DHHS) published laboratory standards regulations (57 FR 7002) implementing the Clinical Laboratory Improvement Amendments of 1988 (CLIA) (42 U.S.C. 263a). The implementing regulations are codified at 42 CFR Part 493. CLIA regulates laboratory testing and requires that clinical laboratories obtain a certificate before accepting materials derived from the human body for the purpose of providing information for the diagnosis, prevention, or treatment of any disease or the impairment of, or assessment of the health of human beings. The type of CLIA certificate a laboratory obtains depends upon the complexity of the tests it performs. CLIA regulations describe the following three levels of test complexity: waived tests, moderate complexity tests, and high complexity tests. 42 CFR 493.5(a).
On January 31, 2000, the responsibility for categorization of commercially available in vitro diagnostic (IVD) tests was transferred from the Centers for Disease Control and Prevention (CDC) to the Food and Drug Administration (FDA) Center for Devices and Radiological Health (CDRH).1 This allows IVD manufacturers to submit premarket notifications or applications for tests and requests for complexity categorization of these tests under CLIA to one agency. Per the December 30, 1999, Notice of the Federal Register, FDA/CDRH’s responsibility for CLIA complexity categorization explicitly applies to clinical laboratory devices:
- under premarket review by CDRH,
- under premarket review by other FDA Centers,
- exempt from premarket notification, and
- that are legally marketed and for which the sponsor is seeking a waiver categorization.
FDA/CDRH’s general administrative procedures vary for each of the categories above and are described within this document. This guidance does not specifically address the recommended content of CLIA waiver applications. For more information on what should be included in CLIA waiver applications, you may refer to the guidance entitled, “Guidance for Industry and FDA Staff: Recommendations for Clinical Laboratory Improvement Amendments of 1988 (CLIA) Waiver Applications for Manufacturers of In Vitro Diagnostic Devices.”
This guidance is updated to include information regarding FDA’s internal administrative processes, including CDRH’s e-copy program which is voluntary for CLIA categorizations.
FDA's guidance documents, including this guidance, do not establish legally enforceable responsibilities. Instead, guidances describe the Agency's current thinking on a topic and should be viewed only as recommendations, unless specific regulatory or statutory requirements are cited. The use of the word should in Agency guidances means that something is suggested or recommended, but not required.
a. Categorization of Clinical Laboratory Devices Under Premarket Review
CLIA categorization of IVD tests is determined by FDA at the time of review of a premarket notification submission (510(k)) or a premarket approval application (PMA) under the Federal Food, Drug, and Cosmetic Act. Upon receipt of a marketing application in CDRH, FDA will automatically create a second discrete submission tracking number for the CLIA process and notify the sponsor of their CLIA Record (“CR”) number in addition to their premarket submission 510(k) (“K”) or PMA (“P”) number. In cases where the premarket submission is reviewed by another FDA Center (e.g., CBER), the other Center will notify CDRH at the time of clearance/approval of the IVD test. At that time, FDA will automatically create a discrete CLIA Record (“CR”) number to track CDRH’s categorization of the test and notify the sponsor of their CLIA Record number.
FDA determines test complexity by reviewing the package insert test instructions in the premarket submission, using the criteria listed in 42 CFR 493.17. The tests that are not waived by regulation under 42 CFR 493.15 and are not cleared or approved for home use or for over-the-counter use, may be categorized either as moderate or high complexity.
FDA will attempt to notify sponsors of the complexity categorization within two weeks of a positive marketing decision (e.g., a substantial equivalence determination for a 510(k) or an approval decision for a PMA). Categorization is effective as of the date of the written notification to the manufacturer (see 42 CFR 493.17(c)(1)(ii)).
A searchable database of CLIA categorizations for IVD devices is available at http://www.accessdata.fda.gov/scripts/ cdrh/cfdocs/cfCLIA/clia.cfm. FDA periodically posts all categorizations in the public CLIA database with reference to the premarket submission number.
b. Request for Categorization of Legally Marketed Devices
In cases where a 510(k) or PMA is not needed but CLIA categorization is still appropriate (e.g., devices exempt from premarket notification), manufacturers should submit a request for CLIA categorization, including a copy of the test package insert with test instructions, to the CDRH Document Control Center at the following address:
Food and Drug Administration
Center for Devices and Radiological Health
Document Mail Center - WO66-G609
10903 New Hampshire Avenue
Silver Spring, Maryland 20993-0002
To expedite review, FDA strongly encourages submission of an eCopy. See “eCopy Program for Medical Device Submissions.”
FDA will assign a discrete CLIA Record (“CR”) number to this submission, notify the sponsor of the tracking number, and attempt to notify sponsors of the categorization within 30 days of the request. FDA will post the categorization in the public CLIA database with reference to the CLIA Record (“CR”) number.
Additionally, FDA recommends that where the name of an approved or cleared device changes, or the name of the manufacturer or distributor changes, the manufacturer should submit the updated label and request for CLIA categorization to the CDRH Document Control Center at the address listed above so that its record of categorized tests in the public database is accurate. When requesting CLIA categorizations for a name change for multiple IVD tests (e.g., manufacturer or distributor device name change), FDA recommends that this information be presented using a spreadsheet (e.g., Excel). Sponsors may download the information for their current categorized tests from the CLIA database using the “export to Excel” function, add a new column to the spreadsheet after the current test system name, and enter the new test system name in this column. The spreadsheet could be provided to CDRH as part of the eCopy. The application should reference one cleared marketing application in the cover letter to expedite processing of the new categorization letters. Upon receipt of a request for categorization due to a manufacturer or distributor name change, FDA will assign a discrete CLIA Record (“CR”) number to this submission, notify the sponsor of the tracking number, and attempt to notify sponsors of the categorization within 30 days of the request. FDA will post the categorization in the public CLIA database with reference to the CLIA Record (“CR”) number.
A test initially categorized as moderately complex might meet the statutory criteria for CLIA waiver if the device is simple to use and the sponsor demonstrates in studies conducted at the intended use sites that the test is accurate and poses an insignificant risk of erroneous results. If a Sponsor of a test categorized as moderate complexity believes their test meets the statutory criteria for CLIA waiver, they may submit a CLIA Waiver by Application to request categorization of the test system as waived. Such a submission should be mailed to the CDRH Document Control Center (DCC) at the address listed above and identified as a CLIA Waiver by Application submission. To expedite review, FDA strongly encourages submission of a validated eCopy per the Guidance Document “eCopy Program for Medical Device Submissions.”
All CLIA Waivers by Application should reference either a cleared/approved marketing application (e.g., 510(k), PMA, BLA) or a Pre-Submission during which agreement was reached on a Dual 510(k) and CLIA Waiver by Application strategy. CLIA Waivers by Application are not accepted for devices that are under premarket review at the time of submission. A Dual 510(k) and CLIA Waiver by Application should contain the complete 510(k) and waiver application in a single submission and is subject to 510(k) Refuse to Accept (RTA) policies outlined in the Guidance Document “Refuse to Accept Policy for 510(k)s.” FDA/CDRH will assign a discrete CLIA Waiver by Application (“CW”) tracking number and notify the sponsor of the tracking number associated with their submission.
Performance goals for CLIA Waiver by Applications filed from FY 2013 through FY 2017 (MDUFA III) are defined as follows in the MDUFA III Commitment Letter.
FY2013 – FY2017
|Dual (510(k) and CLIA Waiver by Application) ||210||90%|
 Note that this performance goal applies to both the CLIA Waiver by Application and the 510(k) marketing submission.
A Substantive Interaction may be a request for Additional Information (via letter or email), a notification that review will Proceed Interactively (via email), or a notification of Waiver Granted (via formal letter). A MDUFA Decision may be a notification of Waiver Granted (via formal letter), notification of Wavier Denial (via formal letter), or withdrawal by the sponsor. The goals for Substantive Interaction and MDUFA Decisions are in terms of FDA Days, which are defined in the MDUFA III Commitment Letter as those calendar days when a submission is considered to be under review at the Agency for submissions that have been accepted. FDA Days begin on the date of receipt of the submission.
Upon notification of a Waiver Granted, FDA will post the waiver categorization in the public CLIA database with reference to the premarket submission number per current practice.
For additional information regarding data to support a CLIA Waiver by Application, refer to the guidance entitled, “Guidance for Industry and FDA Staff: Recommendations for Clinical Laboratory Improvement Amendments of 1988 (CLIA) Waiver Applications for Manufacturers of In Vitro Diagnostic Devices.”
Manufacturers have the option to submit their planned protocols or study designs to support CLIA waiver in order to obtain feedback from FDA prior to conducting the study. These planned protocols or study designs should be submitted to the CDRH Document Control Center (DCC) at the address listed above and identified as a Pre-Submission. For additional information on the Pre-Submission process, please refer to the Guidance “Requests for Feedback on Medical Device Submissions: The Pre-Submission Program and Meetings with Food and Drug Administration Staff.” Pre-Submissions for CLIA Waiver by Applications should include a reference to the original 510(k) or PMA number, the protocol/study design, and a valid eCopy.
