For laboratories with a provider-performed microscopy procedure CLIA certificate, which of the following would NOT be approved?

• A. Urinalysis
• B. Semen analysis
• C. Hematology differential
• D. Wet prep

Answer: (C)

Provider-performed microscopy covers a limited set of in-office, microscope-based exams that clinicians can perform directly on patient specimens. These are designed for simple, targeted observations rather than full laboratory hematology testing. Examining a blood smear to do a hematology differential is a broader, higher-complexity test that typically requires a CLIA-certified laboratory and specialized personnel. In contrast, urine sediment examination, semen analysis, and a wet mount are classic examples of microscopy procedures that clinicians can perform under a provider-performed microscopy certificate. Therefore, the hematology differential would not be approved under this certificate, while the other three in-office microscopic tests would be.
