International External Quality Assessment Program


External quality assurance (EQAS) complements the laboratory's internal control and is an essential tool to verify the accuracy of results and to evaluate the performance of the measurement procedures used by the laboratory. In external control programs, the result obtained in the laboratory is compared with aconsensus value of the results of all participating laboratories examining the same sample.

Since1999, Biosystems S.A., organizes the international program of external quality evaluation PREVECAL that offers to the laboratories the possibility to complete their Internal Control scheme with an objective estimation of the quality of their measurement procedures.

The aims of quality control schemes are, in general, to provide participants with an objective assessment of their performance within their laboratories and in relation to other laboratories, to provide information on the relative performance of the available kits and methods, and to identify factors associated with good and poor performance.

The program is a consequence of BioSystems' policy to actively collaborate with laboratories to achieve analytical results with the lowest possible error.
