Clinical laboratories in Belgium working within the social security system require to be licensed. Internal quality control and participation in external quality assessment (EQA) belong to the licensing conditions. The evolution of the Belgian EQAs is outlined, including a performance evolution over the last ten years. Halving of interlaboratory CVs is observed for most clinical chemistry and immunoassay analytes. Improvement is less spectacular for haematological analytes and is missing for coagulation analytes. Using the results of EQAs 1989-1991 the mean overall method interlaboratory CVs could be estimated. Using data from a commercial internal quality control program for clinical chemistry and a request in 145 laboratories, current intralaboratory CVs are estimated.
在比利时社会保障体系内工作的临床实验室需要获得许可。内部质量控制和参与外部质量评估（EQA）属于许可条件。本文概述了比利时EQA的发展情况，包括过去十年的性能演变。大多数临床化学和免疫分析物的实验室间变异系数（CV）减半。血液学分析物的改善不太显著，而凝血分析物则没有改善。利用1989 - 1991年EQA的结果，可以估算出总体方法的实验室间平均CV。利用临床化学商业内部质量控制程序的数据以及145个实验室的一项要求，估算了当前的实验室内CV。
