What does laboratory quality control aim to detect and correct?

Laboratory quality control is primarily focused on ensuring the accuracy, reliability, and precision of analytical results generated by the laboratory's testing processes. By aiming to detect and correct deficiencies in the laboratory's analytical process, quality control measures help ensure that tests produce valid outcomes that can inform clinical decisions. This encompasses monitoring various aspects of the testing workflow, such as the performance of instruments, reagents, and procedures, and implementing corrective actions if deviations from expected performance are observed.

In a clinical laboratory setting, where the stakes are high, any inaccuracies in analytical processes can lead to misdiagnoses or inappropriate treatments. Therefore, regular quality control checks are essential to validate that the tests being performed uphold the standards required for patient care. By focusing on the analytical processes, the laboratory can maintain stringent quality standards and continuously improve its testing reliability.
