What is the main purpose of quality control in a medical laboratory?

The main purpose of quality control in a medical laboratory is to ensure the accuracy and reliability of laboratory test results. Quality control involves systematic processes and procedures that monitor and evaluate the laboratory's performance. This includes the use of control samples that have known values, regular calibration of equipment, and comprehensive assessments of testing methods.

By implementing quality control measures, laboratories can identify potential errors in testing processes, which helps to minimize occurrences of false positives or negatives. Ensuring accuracy is crucial because laboratory test results directly influence patient diagnosis, treatment decisions, and overall healthcare outcomes. Thus, quality control serves as a safeguard, helping maintain a high standard of precision and consistency in test results, which is essential for patient safety and effective clinical decision-making.
