CLIA Certificate of Waiver lookup
CLIA waiver lookup: how to verify a Certificate of Waiver
As of 2026-06-20, there is no separate public “CLIA waiver registry.” A Certificate of Waiver is one of five CMS certificate types recorded inside a lab's CLIA record, so a CLIA waiver lookup means looking up the lab's CLIA number and reading its certificate-type field in the official CMS QCOR lab lookup.
Where it lives
Certificate field
The Certificate of Waiver is a certificate-type value in the lab's CLIA record, not a standalone waiver database.
What it authorizes
Waived tests only
CMS issues a Certificate of Waiver to a lab that performs only tests the FDA has categorized as waived (simple, low-risk).

SourceCheckHealth shows imported certificate/status fields and links to QCOR; it is not a final CLIA certification or compliance decision.
Definition-first source note
How do you look up a CLIA Certificate of Waiver?
As of 2026-06-20, you verify a Certificate of Waiver by looking up the lab's CLIA number in the official CMS QCOR CLIA lab lookup, or in the downloadable CMS Provider of Services clinical laboratories file, and reading the certificate-type field. CMS issues a Certificate of Waiver to a laboratory that performs only tests categorized as waived; the lab must still hold a CLIA certificate and follow the manufacturer's instructions for each waived test.
Some third-party pages imply there is a dedicated “waiver lookup” database. There is not — the waiver status is the certificate type on the lab's single CLIA record. For any compliance decision, confirm the current certificate type and status in CMS QCOR rather than relying on a cached value.
Unique data dimension
What “waived” means and inspection scope
Waived tests are tests the FDA has determined are so simple that an incorrect result poses little risk of harm. Two consequences of holding a Certificate of Waiver matter for screening:
- Scope is narrow. A Certificate of Waiver authorizes only waived testing. Moderate- or high-complexity testing requires a Registration, Compliance, or Accreditation certificate instead.
- No routine survey. Per the CMS State Operations Manual, labs with a Certificate of Waiver (or PPM) are not subject to routine surveys, so the certificate-type field is your primary public signal of what the lab is authorized to do.
Verification path
Where to confirm a Certificate of Waiver
- 1. Find the CLIA number.Use the lab's CLIA number; if you only have an NPI, confirm identity first, then locate the CLIA record.
- 2. Open CMS QCOR. Look up the CLIA number in the official CMS QCOR CLIA lab lookup and read the current certificate type and status.
- 3. Cross-check the POS file. The CMS Provider of Services clinical laboratories file carries the certificate-type field for bulk review.

FAQ
Practical notes
How do you look up a CLIA Certificate of Waiver?
There is no separate public 'CLIA waiver registry.' The Certificate of Waiver is a certificate-type value inside the lab's CLIA record, so you look up the lab's CLIA number in the official CMS QCOR CLIA lab lookup (or the CMS Provider of Services clinical laboratories file) and read the certificate-type field. SourceCheckHealth shows the imported certificate/status field beside source freshness, then links to QCOR for the current certificate.
What does a CLIA Certificate of Waiver allow a lab to do?
CMS issues a Certificate of Waiver to a laboratory that performs only tests categorized as waived. Waived tests are simple tests the FDA has determined have a low risk of an incorrect result. A lab holding a Certificate of Waiver must still hold a CLIA certificate and follow the manufacturer's instructions for each waived test.
Are Certificate of Waiver labs inspected?
Per the CMS State Operations Manual, laboratories that hold a Certificate of Waiver (or a PPM certificate) are not subject to routine surveys. CMS may still conduct a limited number of validation or complaint surveys. Because routine inspection does not apply, confirm the current certificate type and status in official CMS QCOR before relying on it.
Is a CLIA certificate lookup the same as a CLIA license lookup?
Yes. Labs are authorized under a CLIA certificate rather than a separate license, so a 'CLIA license lookup' or 'CLIA certificate lookup' means reviewing the lab's CLIA certificate type and status. The Certificate of Waiver is one of five CMS certificate types; the others are PPM, Registration, Compliance, and Accreditation.
