摘要:

目的 根据精子浓度室间质量评价(EQA)数据绘制Youden图,以通过EQA回报结果获取更多有效信息,发现系统误差,改进实验室检测质量。方法 收集2019和2020年山东省精子浓度EQA数据,绘制Youden图,分析2019和2020年EQA回报结果。结果 Youden图显示,2020年低浓度水平质控品变异系数(CV)为31%,显著低于2019年(19%)(P<0.05);高浓度水平质控品CV差异无统计学意义(P=0.097)。结论 Youden图可以反映精液分析项目实验室系统误差的趋势,帮助临床实验室更直观地发现系统误差。

Abstract:

Objective According to Youden plot in external quality assessment(EQA) of sperm concentration,to bring more efficient information from EQA report data,to discover systematical errors,and to improve determination quality. Methods The sperm concentration EQA data of Shandong province in 2019 and 2020 were collected,a Youden plot had been drawn,and the EQA report results of 2019 and 2020 were analyzed. Results The coefficient of variation(CV) of quality control meterial at low concentration levels in 2020(31%) was decreased compared with that in 2019(19%)(P<0.05),and the CV of quality control meterial at high concentration levels had no statistical significance(P=0.097). Conclusions Youden plot can reflect the tendency of laboratory systematical errors for sperm concentration,so the participating laboratories can find the systematical errors directly.

Key words: Sperm concentration, Semen analysis, External quality assessment, Systematical error, Youden plot
