External assessment of test quality
Modern methods of laboratory diagnostics make it possible to detect infections with great accuracy. However, to ensure the reliability and efficiency of the test, it is important to systematically check the devices and methods to avoid errors and ensure the accuracy of the results. One of the common practices is external evaluation of the quality of tests.
An approach to testing the effectiveness of HIV testing involves sending doctors specially designed control samples that already have known HIV or antigens. Their use allows you to check how accurately the test responds to known parameters.
The doctors involved in this process receive the samples and test the samples for HIV. The obtained results are compared with the known and any differences are analyzed. This cycle of checks can be carried out periodically, ensuring that the test systems are continuously checked for accuracy and reliability.
If a test shows an incorrect result on a sample with a known result, this may indicate possible testing problems, such as test defects or improper storage of reagents.
This approach helps identify possible problems and ensures reliable results, which are crucial for successful treatment and disease control.
