CLIA Laboratory Search

This tool allows users to search information about CLIA-certified laboratories provided by the Centers for Medicare & Medicaid Services (CMS) using a CLIA number, facility name, address, geographic location, or type of CLIA certificate. Laboratory names should be entered exactly as they appear on the CLIA certificate. This database is updated regularly but users might experience delays in searching for information about recently certified laboratories. For additional information about CLIA laboratories, visit the CMS CLIA Laboratory Demographics Lookupexternal icon and click on CLIA Laboratory Lookup under “Tools”. For questions about a CLIA certificate, contact CMS directly at CMS Lab Excellence.
