Important information about the CLIA proficiency testing final rule

The Centers for Medicare and Medicaid Services (CMS) updated their Proficiency Testing (PT) and PT Referral brochure on their CLIA Brochures website to assist laboratories in preparing for the new regulations.

The brochure will help laboratories complete PT enrollment and place orders with their PT providers for 2025. This guidance will inform laboratories of the upcoming changes necessary for compliance prior to the January 1, 2025 implementation date.

The Clinical Laboratory Improvement Amendments of 1988 (CLIA) Proficiency Testing Regulations Related to Analytes and Acceptable Performance (CMS-3355-F) final rule became effective on July 11, 2024; however, it will not be implemented until January 1, 2025.
