Quality control (QC) refers to the set of procedures and protocols designed to monitor and maintain the precision and accuracy of laboratory equipment and testing processes. It involves daily checks, calibration, and verification to confirm that instruments are operating correctly and producing reliable results. Quality control charts, such as Levey-Jennings charts, are graphical tools that display QC data over time. They help identify trends or deviations in test results.

Quality assurance (QA) takes a broader approach, focusing on the entire laboratory testing process rather than just the equipment. QA encompasses a set of systematic activities and processes aimed at providing confidence that the laboratory consistently produces accurate and reliable results.
