Abstract
Objective To use the Z-scores as a means of evaluating the results of external quality assessment(EQA),so as to improve the quality control management in laboratories.Methods Z-scores control charts were plotted based on the feedback results of nucleic acids EQA from the National Center for Clinical Laboratories from 2021 to 2023,and EQA man-agement was conducted using Westgard quality control rules.Results In the EQA from 2021 to 2023,the Roche testing system experienced runaway event in the HBV sample minipool testing,while all other items were under control.For KH testing system,runaway events occurred in HCV sample minipool testing and HBV samples resolution,and a warning was is-sued for the resolution detection of HIV samples,while other items were under control.Conclusion The Z-score control chart can achieve continuous monitoring of EQA results,and the use of Westgard quality control rules for quality assessment management can identify the types of errors,which can help enhance the laboratory's quality management and control capa-bilities,and ensure the accuracy of laboratory nucleic acid test results.关键词
