> 2,185 laboratories hold an active CLIA Certificate of Registration. What the certificate allows, and the count by state.

## Certificate of Registration

2,185 laboratories hold this certificate in the CMS file for Q2 2026.

### What it allows

Issued first to a laboratory that applies to perform moderate or high complexity testing: it lets the laboratory test until an inspection determines whether it meets the CLIA requirements.

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.
