CLIA case studies
CLIA · Put your knowledge to work in context.
The Clinical Laboratory Improvement Amendments (CLIA) framework governs laboratory testing in the United States, and proficiency testing (PT) is one of its central quality mechanisms: laboratories enrolled in approved PT programs must test unknown challenge samples and have their results compared against peer groups and grading criteria. This certification-style exam targets laboratory personnel who need working command of that framework - directors, technical supervisors, general supervisors, testing personnel, and quality or compliance staff who prepare for PT enrollment, handle PT specimens, review PT reports, and respond to PT failures. The CLIA case studies are 5 cases and about 3,411 words.

During a CLIA survey of a moderate-complexity laboratory, the surveyor finds three condition-level deficiencies: (1) expired reagents were used for chemistry testing for three months; (2) the laboratory did not enroll in proficiency testing for one specialty it reports; and (3) competency assessment was missing for two technologists hired eight months ago. The laboratory director says the problems are "paperwork issues" and wants to correct them after the survey without notifying anyone.
