What is the main focus of quality control in laboratory testing?

The main focus of quality control in laboratory testing is to ensure the accuracy and reliability of test results. Quality control processes are essential because they help laboratories to monitor and maintain the performance of their equipment, reagents, and procedures. By implementing rigorous quality control measures, laboratories can identify any issues that may affect the validity of test results, such as improper handling of samples, calibration errors, or reagent deterioration. Accurate and reliable results are crucial for diagnosing and managing patient care, as they directly impact clinical decision-making.

While aspects such as reducing costs, promoting services, and improving aesthetics may be considerations in a laboratory's overall functioning, they are not the primary focus of quality control. The fundamental goal remains the integrity of testing processes to provide safe and effective patient care.
