2019年陕西省碘缺乏病实验室碘外质控网络考核结果分析

Analysis on urinary and salt and water iodine external quality control network results for iodine deficiency disorders laboratories in Shaanxi Province in 2019

目的分析评价2019年陕西省碘缺乏病(IDD)实验室碘外质控网络运行相关的情况,了解各级实验室的检测情况,总结陕西省三级实验室的检测水平,为碘缺乏病防治工作提供技术支持。方法盐碘、水碘的检测结果均采用标准参考值±不确定度的方法进行统计学评价;尿碘检测结果采用Z比评分法进行统计学评价。结果省级和所有市级实验室参加全部的尿碘、盐碘、水碘考核,54个县级实验室参加水碘考核,39个县级实验室参加盐碘考核,全省所有的107个县级实验室全部参加尿碘考核。省、市、县三级实验室的水碘、尿碘、盐碘检测结果均通过了国家的外质控考核,反馈率和合格率均为100.00%。结论通过多年的实验室网络运行和持续的技术培训,陕西省三级碘缺乏病实验室的尿碘、盐碘、水碘检测水平均稳步提高,实验室检测能力稳定可靠,实验室网络运行情况良好,能为碘缺乏病的防治提供科学可靠的实验室技术支持。

Objective To analyze the operation situation of iodine external quality assessment network of iodine deficiency disorders(IDD)laboratories in Shaanxi Province in 2019,to understand the testing ability of all laboratories,to summarize the detectability and proficiency testing for IDD laboratory in Shaanxi province at all levels,to provide the technical support for IDD.Methods The testing results of salt iodine and water iodine are analyzed with reference value±uncertainty,urinary iodine are statistically analyzed with Z score method.Results All 1 provincial and 10 municipal laboratories take part in the testing of urinary iodine and water iodine and salt iodine.All 39 county laboratories take part in the testing of salt iodine.All 107 county laboratories take part in the testing of urinary iodine.All 54 county laboratories take part in the testing of water iodine.The testing results of provincial,municipal and county third-level laboratories had all passed the external quality control assessment.Both the feedback rate and qualified rate of the testing results are 100.00%.Conclusions The testing ability at all level laboratories has been improved through the national laboratory network operation and technical training.The external quality assessment network of urinary and salt and water IDD laboratories in Shaanxi Province runs good.The testing ability of all levels laboratories are stable and reliable,it can provide scientific and reliable laboratory technical support for surveillance and control of IDD.
