What regulation governs the testing standards for clinical laboratories in the United States?

CLIA, the Clinical Laboratory Improvement Amendments, sets the federal quality standards for all laboratory testing performed on humans in the United States. It ensures that tests are accurate, reliable, and timely by establishing certification categories (waived, moderate, and high complexity), requiring quality control and proficiency testing, specifying personnel qualifications, and mandating regular inspections. This framework applies to virtually every clinical lab—from hospital labs to independent reference labs—so patient results are trustworthy regardless of where the test is done. HIPAA concerns protecting patient information privacy, FDA regulates medical devices and some test approvals, and OSHA covers workplace safety. These areas are important but they do not establish the overarching testing standards for clinical laboratories the way CLIA does.
