Laboratories applying for or holding a New York State (NYS) clinical laboratory permit must participate in proficiency testing (PT) as defined by NYS (NYS mandated PT).  NYS mandated PT includes all tests/analytes offered by the laboratory that are either listed in CMS 42 CFR 493 subpart I (CLIA subpart I) OR defined by NYS as requiring PT.

CLEP has screened PT products offered by the CMS-approved PT providers to identify those that meet New York State PT requirements for NYS mandated PT analytes.

Other products offered by these providers do not meet these requirements, but may fulfill requirements for other analytes under NYS Clinical Laboratory Standard Proficiency Testing Standard of Practice (PT S3): Alternative to Proficiency Testing

Use the search tool below to identify analytes that require PT and the products that satisfy PT requirements. 

  1. Choose a CLEP permit category from the dropdown menu.
  2. Click the search icon.
  3. The search will create either a message about PT requirements for that category or an "Analyte" dropdown menu. Select an analyte and click the search icon again to create a list of acceptable PT products that include the analyte."
