What is the purpose of quality control in laboratory testing?

The purpose of quality control in laboratory testing is to ensure the accuracy and reliability of test results. Quality control involves systematic processes and procedures that monitor and evaluate the performance of testing methods and the equipment used in laboratories. By implementing quality control measures, laboratories can identify and correct any potential errors or inconsistencies in test results, thereby providing confidence in the data that is used for patient diagnosis and management.

Accurate and reliable test results are crucial in the medical field; they directly impact patient care and treatment decisions. Quality control practices, such as running control samples alongside patient samples and regular calibration of testing instruments, help to maintain high standards in testing protocols and improve overall laboratory performance.

Enhanced accuracy contributes to better patient outcomes, as healthcare providers can rely on the results to make informed decisions. While speeding up test results, reducing costs, or improving layout and design can also be important elements in laboratory management, they do not address the foundational purpose of ensuring the integrity and validity of the test results themselves, which is the essence of what quality control stands for in this context.
