In each inter-laboratory comparison, the participants carry out one or more tests on the same sample. Each laboratory compares its own results with those of the others, thus ensuring constant self-verification of its own testing capabilities and, at the same time, a broad spectrum verification of the performance and reliability of the laboratory itself. The evaluation of the laboratory’s performance is expressed in the standard "z-score" which expresses, from a statistical point of view, how much the laboratory result differs from the most probable result, also called the “assigned value”. Participation in inter-laboratory evaluation tests is an adequate and independent self-control tool that helps to improve the quality of the services offered. The national and international Proficiency Test suppliers chosen by Bonassisa laboratories are accredited according to the ISO/IEC 17043 standard.
