Quality control in a laboratory

tubeLaboratory quality control is designed to detect deficiencies in the analytical process, in order to reduce, correct and improve the quality of the analysis and results developed in the lab.

The aim of the quality control is to evaluate the results reproducibility, that is a measure of precision to know how well the laboratory technique reproduces the same result. The quality tests must be run variying operating conditions too.

In general, the quality controls must be run after instrument service, at the beginning of each shift, after the instrument calibration and any time the results fall outside the expected values range.

The quality control measurements and tests results must be tracked and recorded. The annotation matrix and forms should be easy to fill and simple to use. The use of controls is the most common method to test the accuracy and reproducibility of the measurements.
