A method for the evaluation of results in external quality control surveys is developed on purely statistical grounds. This system allows to establish accuracy and precision of assay methods by comparing statistical data from subsequent surveys. However, for a particular survey the overall accuracy, precision and quality of each laboratory are defined in statistical terms and visually displayed. Results for each laboratory are summarized on a two-page computer printout. Per component assayed and combining all components determined in the particular survey, the laboratory is assigned one of the four possible qualifications i.e. "very good", "moderate" or "bad". A few general conclusions drawn from experimental data of previous surveys are reported.
基于纯粹的统计学依据,开发了一种用于评估外部质量控制调查结果的方法。该系统通过比较后续调查的统计数据,能够确定检测方法的准确性和精密度。然而,对于特定的一次调查,每个实验室的总体准确性、精密度和质量是从统计学角度定义并直观显示的。每个实验室的结果总结在一份两页的计算机打印输出上。针对特定调查中测定的每个成分,并综合所有已测定的成分,为实验室赋予四种可能的资质之一,即“非常好”“中等”或“差”。报告了从前几次调查的实验数据中得出的一些一般性结论。
