2016-2018年山东省县区级尿碘实验室质量控制和能力验证情况分析

Analysis of quality control and test ability of urinary iodine in local laboratories of Shandong Province from 2016 to 2018

目的分析山东省县区级尿碘实验室外质控考核结果及网络运行情况,评价其持续检测能力。方法2016年全省选取65个县区级尿碘实验室参加省级外质控考核,2017年选取124个县区级尿碘实验室参加国家级外质控考核,2018年全省137个县区级尿碘实验室均参加国家级外质控考核。外质控结果采用Z比评分法进行分析(|Z|≤2为合格;2<|Z|<3为基本合格,|Z|≥3为不合格)。结果2016年参加省级外质控考核的实验室中有60个进行了反馈,反馈率为92.3%(60/65),合格率为81.7%(49/60);2017年参加国家级考核的124个县区级实验室均进行了反馈,反馈率、合格率均为100.0%(124/124);2018年参加国家级外质控考核的137个县区级实验室均进行了反馈,反馈率、合格率均为100.0%(137/137)。结论山东省县区级尿碘实验室检测能力持续上升,初步达到了全省所有县区级尿碘监测全覆盖要求的检测水平。

Objective To analyze the assessment results of the external quality control and network operation of urinary iodine in local laboratories of Shandong Province,to evaluate the ability of consistent analysis.Methods In 2016,there were 65 county-level urinary iodine laboratories participated in the provincial external quality control assessment,and there were 124 county-level urinary iodine laboratories participated in the national external quality control assessment in 2017.In 2018,all 137 county-level urinary iodine laboratories in the province participated in the national external quality control assessment.The testing results were analyzed with Z score method(qualified:|Z|≤2;basically qualified:2<|Z|<3;unqualified:|Z|≥3).Results The 65 county-level laboratories in Shandong Province were evaluated in the provincial quality control test of urinary iodine in 2016,the feedback rate was 92.3%(60/65),the overall qualified rate was 81.7%(49/60);124 county-level laboratories in Shandong Province were evaluated in the national quality control test of urinary iodine in 2017,the feedback and qualified rate were both 100.0%(124/124).All the 137 county-level laboratories were evaluated in the national quality control test of urinary iodine in 2018,the feedback and qualified rate were both 100.0%(137/137).Conclusions The test abilities of urinary iodine in local laboratories of Shandong Province has been increasing continuously,and it has initially reached the detection level required for the full coverage of urinary iodine monitoring in all counties of the province.
