参加室间质评加强免疫检验项目的质量控制

PARTICIPATING EXTERNAL QUALITY ASSESSMENT AND IMPROVE LABORATORY QUALITY CONTROL

目的:能力比对检验(proficiency testing,PT)是室间质量评价的重要方案,通过参加全国临床检验中心(National center for clinical laboratory,NCCL)组织的室间质评活动,监控实验室分析性能,确保检测结果的准确性、可重复性和可比性,促进实验室质量改进。方法:我们免疫组2008年参加NCCL组织的肿瘤标记物、激素类、传染类检验项目的能力验证活动,连续9批测试。实验室收到标本后,在10d内检测完毕,将检测结果回报给NCCL。NCCL在同方法组内对检测结果进行评估,并提供所有参与实验室的结果统计报告。同时每日做肿瘤标记物、激素类的室内质控。结果:36项测定指标390个检测结果,379个符合NCCL标准,合格率达97.3%。室内质控肿瘤标记物、激素类均值稳定,不精密度(CV%)符合总误差要求,并逐渐缩小。结论:通过参加NCCL能力比对检验,实现了对实验结果准确性的持续性监测,达到提高人员素质,加强质量控制的目的。

Objective：Participating NCCL proficiency testing（PT） to evaluate and improve laboratory performance.Methods：Participating NCCL proficiency testing on tumor markers and hormones in 2008.Each survey carries out nine times a year.Laboratory should send the results back to NCCL within 10 days after receiving the specimen.NCCL evaluates the results using comparable peer groups and provides a report summarizing the results of all participating laboratories.Meanwhile external quality assessonent of tumor markers and hormones were deteced every day.Results：379 in the total of 390 test results on 36 test items were accorded with NCCL standard and the qualified rate reached to 97.3%.curves of tumor markens and hormones appeared stable.cv% moeted the reqaire ments of total errol and appeared less gradually.Conclusion：Participating NCCL proficiency testing is a good way to monitor the accuracy and liability of test results continuously,and improve staff work capability and quality control management.
