National Committee for Clinical Laboratory Standards (NCCLS)

The National Committee for Clinical Laboratory Standards (NCCLS) was an organization that developed and published guidelines to ensure consistency, accuracy, and quality in clinical laboratory testing. Its purpose was to help laboratories follow standardized procedures for testing various medical samples, which improves reliability of results for diagnosis and treatment. NCCLS’s work helped laboratories worldwide adopt best practices, though it has now been integrated into other organizations. Essentially, NCCLS played a key role in promoting high standards in medical testing to support effective healthcare.
