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.
