A procedure is described to judge the quality of clinical chemistry hospital laboratories in The Netherlands. In 1974, 45% of the laboratories took part in the national control scheme. A score system of the results, independent of the standard deviation, opens a provisional possibility to strive for (dynamic) reference laboratories. The Youden plots possibly will unveil systematic method-differences. Discrepancies in results seem to be caused as much by methods/instruments applied, as by unknown factors which are under investigation now.
本文描述了一种用于评判荷兰医院临床化学实验室质量的程序。1974年，45%的实验室参与了国家质量控制计划。一种不依赖于标准差的结果评分系统为争取（动态）参考实验室提供了一种暂时的可能性。尤登图可能会揭示系统的方法差异。结果差异似乎同样是由所应用的方法/仪器以及目前正在研究的未知因素造成的。
