What role does a control solution play in POCT?

A control solution in point-of-care testing (POCT) plays a crucial role in verifying that the testing device is functioning properly. The use of control solutions allows healthcare professionals to assess whether the device is producing accurate and reliable results before performing tests on patient samples. Control solutions contain known concentrations of analytes and are used to simulate patient samples; therefore, when the device is tested with these controls, it provides a benchmark to compare against expected outcomes.

If the test yields results within the expected range when using the control solution, it indicates that the device is functioning correctly, and the subsequent patient test results can be trusted for accuracy. This quality control process is essential in ensuring patient safety and the validity of the tests conducted in a POCT setting.
