我国精液分析外部质量评价中的问题及改进建议

Problems and improvement suggestions in external quality assessment of semen analysis in China

外部质量评价(EQA)是评价实验室检测结果是否准确,督促各实验室提高检验质量的主要方式。我国精液分析项目的EQA还处于起步阶段,仅在部分地区开展。在已经开展的评价EQA活动中,还存在一些不足,比如:①评价活动中所确定的合格值区间过大,不利于发现实验室的系统误差;②以人员操作的现场考核成绩代替对实验室的评价;③实验室在评价活动中采用与日常检测不一致的检测系统;④组织者对参评实验室的室内质控关注不够;⑤EQA评价结果的应用范围较局限等。这些不足可能会导致评价活动的成绩无法真实反映实验室检验质量,亟须进行改进提高。

External quality assessment(EQA)is the main way to evaluate whether the test results are accurate,and promote all laboratories to improve the testing quality.The EQA of semen analysis projects in China is still in its infancy and is only carried out in some areas.In the evaluation activities,there are some deficiencies,such as:(1)Evaluation activities for the results of the permissible range is too large,which may be not conductive to discovering systematical errors in the laboratory.(2)Allowing onsite assessment scores for personnel operations to replace laboratory evaluation;(3)The detection system in the evaluation activities adopt inconsistent with daily detection system;(4)The organizer pays insufficient attention on internal quality control of the participating;(5)The application scope of EQA results is limited,etc.These deficiencies may result in the performance of the evaluation activities not truly reflecting to the laboratory testing capacity,which need further improvement.
