Which CLIA certificate allows provider-performed microscopy?

• A. Certificate of Waiver
• B. Certificate of Registration
• C. Certificate of Accreditation
• D. Certificate of Provider Performed Microscopy

Answer: (D)

CLIA categories determine what tests may be performed and under what supervision. Provider-performed microscopy is a specific category that allows a physician or other qualified practitioner to perform certain microscopic examinations during patient care in a clinic or office setting. To do this legally, the facility must hold the Certificate of Provider Performed Microscopy, which is dedicated to approving and overseeing these in-office microscopic procedures.

This certificate is distinct from other CLIA certificates because it is limited to provider-performed microscopic work done in the clinical setting, rather than general laboratory testing or cellular/microscopy work that falls under moderate or high complexity testing. The Waiver certificate covers simple tests that CMS has determined pose minimal risk if performed incorrectly, the Registration certificate is an initial permissive status for labs starting out, and Accreditation/Certification relates to more extensive, external review-based compliance for higher-complexity testing.

So, to perform provider-performed microscopy in a clinical setting, the approved credential is the Certificate of Provider Performed Microscopy.
