Clinical Laboratory Improvement Amendments (CLIA)
The Clinical Laboratory Improvement Amendments of 1988 (CLIA) regulations include federal standards applicable to all U.S. facilities or sites that test human specimens for health assessment or to diagnose, prevent, or treat disease. CDC, in partnership with CMS and FDA, supports the CLIA program and clinical laboratory quality. Learn more about CLIA.
CDC has Retired the Laboratory Search Tool
On January 16, 2024, CDC retired its CLIA Laboratory Search tool. You can find laboratory demographic information on the CMS website, here: https://qcor.cms.gov/basic_research.jsp. Select “CLIA Laboratory Lookup” under “Tool” in the left-hand navigation. Please email CMS directly at LabExcellence@cms.hhs.gov for inquiries about data in their lookup.
