Accreditations & Licensure

Crestar Labs is certified by the Center for Medicare and Medicaid Services, as required by the Clinical Laboratory Improvement Amendment (CLIA), and accredited through the College of American Pathologists (CAP). Our accreditation standards and proficiency testing requirements ensure procedural uniformity, testing integrity and reporting accuracy. We have confidence that our reports, in the hands of the provider, contributes to optimized patient care.


The Clinical Laboratory Improvement Amendments (CLIA) outline a federally mandated program for regulating laboratories that perform testing on patient specimens in order to ensure accurate and reliable test results. CLIA certification, in the state for which the laboratory is located, allows that laboratory to accept samples from most states.
