Which regulatory bodies govern drug testing laboratories in the United States and generally require proficiency testing, QC, documentation, and trained personnel?

• A. FDA, EPA, NRC
• B. CLIA, CAP, SAMHSA, DOT, OSHA
• C. NIH, WHO, IATA
• D. DEA, FDA, CMS

Answer: (B)

Proficiency testing, QC, documentation, and trained personnel are ensured through a layered regulatory framework in the United States. The main framework is CLIA, which sets federal standards for all clinical laboratories and requires ongoing quality assurance, external proficiency testing, documented QC practices, and properly qualified personnel to run tests. Accreditation by CAP is commonly pursued by labs to prove adherence to rigorous quality systems and to participate in peer inspections that go beyond CLIA requirements. For labs handling federally regulated drug testing, SAMHSA and DOT impose additional requirements, including participation in approved proficiency testing programs and strict QA procedures tailored to drug screening. OSHA adds workplace safety and training obligations, ensuring staff are trained in handling specimens and lab hazards. Taken together, these agencies cover the essential elements of proficiency testing, QC, documentation, and trained personnel.
