> 245,489 laboratories hold an active CLIA Certificate of Waiver. What the certificate allows, and the count by state.

## Certificate of Waiver

245,489 laboratories hold this certificate in the CMS file for Q2 2026.

### What it allows

Issued to a laboratory that performs only waived tests — simple tests with a low risk of an incorrect result, such as many rapid point-of-care tests.

A certificate says which tests a laboratory may perform. It does not grade the laboratory.

**For owners and managers: does your
organization have 30 to 200 employees?**

AI labs pay companies to license their internal workflows (SOPs,
documentation, support tickets), anonymized and under contract — never patient data. You keep ownership and pay
nothing.
