Complexity, certificates, and personnel roles

Use the governing complexity criteria for the exact test system. Where the applicable regulatory conditions assign a score of 12 or less, the test is moderate complexity; where they assign a score above 12, it is high complexity. The score alone is not an absolute classification outside those governing conditions.

An FDA clearance or approval does not by itself make a test waived; waived status requires a specific waiver determination, by regulation, by over-the-counter or home-use clearance, or through a CLIA Waiver by Application, so the laboratory has to verify the current categorization of the exact test system rather than assume it from the analyte. A laboratory-developed test, or any test run modified from the manufacturer's instructions, is categorized by default as high complexity, because it was never run through the FDA scorecard as cleared.

The certificate a laboratory holds has to match its highest complexity testing. There are five CLIA certificate types. A Certificate of Waiver authorizes only waived tests; it does not exempt the facility from CLIA, and the laboratory still needs an active certificate and current manufacturer instructions. A Certificate for Provider-Performed Microscopy authorizes only the specific listed PPM procedures, generally bright-field or phase-contrast microscopy, plus waived testing; it is not a general moderate-complexity certificate.

A Certificate of Registration is temporary, letting a laboratory begin nonwaived testing while it awaits its initial inspection, and it ends when a Certificate of Compliance or Certificate of Accreditation is issued. A Certificate of Compliance follows direct inspection by CMS or a state survey agency acting for CMS. A Certificate of Accreditation follows accreditation by a CMS-deemed organization, which inspects in place of CMS, though the laboratory still holds a CLIA certificate and stays subject to CLIA regardless.

For a personnel decision, work from the candidate record: determine the test complexity and role; open the current primary pathway; verify credentials, transcripts, and experience; apply state and accreditor overlays; then assess the appointment date. Do not treat a job title or a memorized pathway as verification.

For a potential grandfathering pathway, resolve the appointment date and continuous service from the current primary text. Do not rely on memorized 2024 wording.

If state law bars an otherwise matching federal pathway, do not appoint under that pathway. Use an allowed route or escalate the record under the current process.

Because of that recent change, do not memorize a personnel pathway as fixed; verify the current eCFR (Electronic Code of Federal Regulations) text and the applicable date at the time of appointment. Match the test's complexity to the correct numbered section first, then match the candidate's exact credential to a numbered pathway inside it, rather than to a general impression that the degree "sounds right."
