目的对2013-2015年安徽省血液中心确证实验室参加的室间质评反馈结果进行总结分析,进一步提高实验室检测水平。方法本室对室间质评活动发放的样品进行检测,完成后将检测数据进行上报,活动结束后根据项目组反馈的结果,及时发现实验室检测过程中出现的偶然误差和系统误差,积极查找原因,提出整改措施。结果本室2013-2015年参加的国家CDC PT室间质评项目反馈结果,除2014年抗-HIV(新创)定性结果符合性为90%,其余项目定性结果符合性均为100%。CITIC室间质评项目中进口试剂检测结果离群结果较少,稳定性较好;国产试剂检测反应性标本离群结果较多,且均高于均值水平,通过调试全自动酶免分析仪,严格按照要求加强样品检测前处理等改进措施,离群结果有所减少。结论通过参加室间质评活动,能够发现实验室在检测前,检测中,检测后等过程中存在的问题,积极整改,显著提高实验室检测水平。
Objective To summarize and analyze the results of laboratory quality assessment feedback from 2013-2015 confirmatory laboratory of blood center in Anhui Province to further improve the level of laboratory testing. Methods In this room, the samples released from laboratory quality assessment activities were detected. After the test was completed, the test data was reported. After the activity was finished, according to the feedback from the project team, occasional errors and systematic errors occurred in the laboratory testing were detected in time, Reason, put forward rectification measures. Results The feedback results of the national CDC PT inter-office quality assessment programs from 2013 to 2015 were consistent with the qualitative results of 90% for anti-HIV (new start) in 2014 and 100% for the remaining projects. In the CITIC inter-laboratory quality assessment project, the results of imported reagents showed less outlier results and better stability; the reactivity test results of domestic reagents were more and more than the mean values, In strict accordance with the requirements to strengthen the sample testing and other improvement measures, the outlier results have been reduced. Conclusion By participating in the inter-laboratory quality assessment activities, we can find out the problems existing in the laboratories before, during, and after testing, and actively rectify and improve the laboratory testing standards significantly.
