## Certificate of Compliance

15,087 laboratories hold this certificate in the CMS file for Q2 2026.

### What it allows

Issued after an inspection by the state agency finds the laboratory in compliance with the CLIA requirements for moderate or high complexity testing.

**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.
