1Under CLIA '88, how many categories of test complexity are defined for laboratory testing?
A.Two
B.Three
C.Four
D.Five
Explanation: CLIA defines testing in four complexity categories in ascending order: waived, provider-performed microscopy (PPM), moderate complexity, and high complexity. The director's qualifications and the regulatory requirements escalate with complexity.
2A Certificate of Waiver under CLIA permits a laboratory to perform only which tests?
A.Moderate complexity tests
B.High complexity molecular tests
C.Provider-performed microscopy procedures
D.CLIA-waived tests performed per manufacturer instructions
Explanation: A Certificate of Waiver authorizes a facility to perform only tests categorized as waived, and they must be performed according to the manufacturer's instructions. The certificate is valid for two years.
3For CLIA regulatory purposes, provider-performed microscopy (PPM) procedures are categorized at what complexity level?
A.Waived
B.High complexity
C.Moderate complexity
D.Exempt from CLIA
Explanation: PPM procedures are a subset of moderate complexity testing performed by a physician, midlevel practitioner, or dentist during a patient visit. Although a dedicated PPM certificate exists, the facility must meet moderate complexity CLIA requirements for those tests.
4Which CLIA certificate is initially issued to a laboratory that has applied for a Certificate of Compliance or Accreditation, allowing it to test while awaiting its survey?
A.Certificate of Waiver
B.Certificate of PPM
C.Certificate of Exemption
D.Certificate of Registration
Explanation: The Certificate of Registration permits a laboratory to perform moderate and/or high complexity testing until its survey is completed and compliance is verified. It is a temporary certificate issued during the application process.
5A Certificate of Accreditation under CLIA differs from a Certificate of Compliance primarily in that the laboratory is surveyed by which entity?
A.A CMS-approved private accreditation organization rather than CMS/the state
B.The FDA rather than CMS
C.The laboratory director rather than an external surveyor
D.OSHA rather than CMS
Explanation: With a Certificate of Accreditation, the laboratory is inspected by a CMS-approved accreditation organization (such as CAP or COLA) that holds deemed status, rather than directly by CMS or a state agency. Both certificates allow moderate and/or high complexity testing.
6Which federal agency administers the CLIA program and issues CLIA certificates?
A.FDA
B.CDC
C.CMS
D.OSHA
Explanation: The Centers for Medicare & Medicaid Services (CMS) administers the CLIA program and issues certificates. The FDA categorizes test complexity and the CDC provides scientific/technical guidance, but CMS holds regulatory authority.
7CLIA regulations for laboratory requirements are codified in which section of the Code of Federal Regulations?
A.21 CFR Part 820
B.29 CFR 1910.1030
C.42 CFR Part 493
D.42 CFR Part 482
Explanation: 42 CFR Part 493 contains the CLIA laboratory requirements, including certification, personnel, quality systems, and proficiency testing. A high complexity laboratory director must be familiar with this regulatory framework.
8Which federal agency assigns the complexity category (waived, moderate, or high) to a commercially marketed test system?
A.FDA
B.CMS
C.CDC
D.CAP
Explanation: The FDA categorizes each commercially marketed test system as waived, moderate, or high complexity, generally at the time of clearance or approval, using a scorecard of seven criteria. CMS then enforces the corresponding CLIA requirements.
9A laboratory that develops a laboratory-developed test (LDT) from scratch, with no FDA clearance, must categorize that test at which complexity by default?
A.Waived
B.Moderate complexity
C.High complexity
D.PPM
Explanation: Tests not categorized by the FDA, including laboratory-developed tests and modifications of FDA-cleared methods, default to high complexity under CLIA. This triggers full validation and high complexity personnel requirements.
10To qualify as a director of a high complexity laboratory under CLIA with an earned doctoral degree, the individual must also generally hold what credential?
A.A state business license
B.A nursing license
C.An MBA degree
D.Board certification by an HHS-approved board
Explanation: A high complexity laboratory director with an earned doctoral degree in a chemical, physical, biological, or clinical laboratory science must be certified by an HHS-approved board (such as ABB) and meet experience and continuing education requirements. The American Board of Bioanalysis is one such approved board.
