What does the Clinical Laboratory Improvement Amendments (CLIA) establish?

The correct response highlights that the Clinical Laboratory Improvement Amendments (CLIA) are designed to ensure the quality and reliability of laboratory testing. CLIA establishes quality standards that laboratories must follow to guarantee the accuracy, reliability, and timeliness of test results. These standards encompass various aspects, including personnel qualifications, equipment, facilities, safety, and quality control measures.

This focus on laboratory testing ensures that all tests performed in clinical laboratories meet certain performance criteria, which in turn protects patients by ensuring they receive accurate diagnoses and appropriate treatments based on reliable test results. While other options mention important areas related to healthcare, they do not directly align with CLIA's primary purpose of standardizing laboratory quality.
