定量检测系统的方法学性能验证实验结果的评价

Evaluation on the acceptability of method performance validation for quantitative tests

检验科对每一检测项目的临床允许误差与所进行的精密度和准确度验证实验观察的检测系统的总误差进行比较,运用 Westgard 方法决定图初步判定检测系统的方法学性能。此外,检验科需对精密度和准确度以外的分析性能验证实验的结果的可接受性进行判定,从而对检测系统的所有方法学性能验证实验结果进行综合评估,最终判断整个检测系统的可接受性。

We compared the total errors observed from both precision and accuracy validation experiments with defined medically allowable errors for each quantitative test, and used Westgard＇s method evaluation decision chart for initial judgement of the acceptability of method validation performance. Moreover, we need to judge the acceptability of other method validation parameters, so that we could integratedly assess and judge whether the testing system is acceptable to use in the laboratory.
