摘要
目的利用Westgard标准决定图分析常用临床生化检测系统性能的可接受性。方法分别以室内质控数据计算各检测项目的日间不精密度,以室间质控回报结果计算不准确度,在Westgard标准决定图上确定标准化操作点,判断生化检测各项目的方法性能。结果参与室间质评的19个常规生化项目中,氯(Cl-),γ-谷氨酰转移酶(GGT)为临界分析性能,其余各项分析性能优良。结论通过定期以Westgard标准决定图对检测系统进行评价,可有效地发现检测系统性能的改变,为提高实验室的工作质量提供保障。
Objective To evaluate the analytical quality of usual laboratory test items with the application of Westgard method decision chart.Methods The intraday inaccuracy was calculated from external quality control data and the imprecision from the internal quality control data.The acceptability of the 19 tests was demonstrated with method decision chart.Results The performances of two items（Cl-,GGT）were marginal and all the others were perfect.Conclusion Regular decisions on the assay system with the method evaluation decision chart should be made,which would be helpful in finding the problems of the assay system effectively and providing guarantee for increasing the working quality of laboratory.
