Which term describes a program dedicated to monitoring the entire testing process to ensure the highest quality of patient care?

• A. Quality assessment
• B. Quality assurance
• C. Quality control
• D. Quality systems

Answer: (A)

Quality assurance is a planned, systematic program that oversees every step of the laboratory testing process, from specimen receipt and handling through reporting of results, with the goal of preventing errors and ensuring reliable patient care. It encompasses establishing and following standard operating procedures, ongoing staff training, regular instrument calibration and maintenance, participation in proficiency testing, routine internal and external audits, and continuous process improvement. This is a proactive, process-wide approach designed to keep quality in focus at all stages, rather than just checking a final product.

Quality assessment, in contrast, tends to evaluate quality after processes have occurred, looking at outcomes and performance indicators to determine how well standards were met. Quality control involves the hands-on checks during testing—such as running controls and calibrators—to verify analytic accuracy at the bench. Quality systems describe the broader governance framework that includes QA, QC, documentation, and policy, within which QA operates as a key component.
