摘　　要：目的了解云南省各级碘缺乏病实验室外质控考核结果,为碘缺乏病的监测提供技术保障。方法2023年,云南省省、市(州)、县级碘缺乏病实验室根据其所参加外质控考核项目(尿碘、盐碘、水碘),检测由国家碘缺乏病参照实验室随机提供的考核样品。未使用全自动碘元素检测仪的实验室,尿碘检测采用《尿中碘的测定第1部分:砷铈催化分光光度法》(WS/T 107.1—2016),盐碘检测采用《制盐工业通用试验方法碘的测定》(GB/T 13025.7—2012)中的直接滴定法,水碘检测采用硫酸铈催化分光光度法。检测结果采用参考值±不确定度的方法进行评价。结果共146个碘缺乏病实验室参加外质控考核,其中省级1个、市(州)级16个、县级129个。省、市(州)、县级碘缺乏病实验室尿碘、盐碘结果反馈率及考核合格率均为100%(146/146);省、市(州)、县级碘缺乏病实验室水碘结果反馈率及考核合格率均为100%(17/17)。结论2023年云南省碘缺乏病实验室外质控考核全部合格,检测质量稳定,可为云南省碘缺乏病监测提供可靠的实验室技术保障。Objective To investigate the external quality control assessment results of iodine deficiency disorders(IDD)laboratories at all levels in Yunnan Province,so as to provide technical support for IDD monitoring.Methods In 2023,all IDD laboratories at provincial,city(prefecture)and county level in Yunnan Province tested the assessment samples randomly provided by the National IDD Reference Laboratory based on their participation in external quality control assessment projects(urinary iodine,salt iodine,water iodine).For laboratories that do not use fully automatic iodine detectors,urinary iodine detection was carried out using the"Determination of Iodine in Urine-Part 1:As 3+-Ce 4+Catalytic Spectrophotometry"(WS/T 107.1-2016),salt iodine detection was carried out using the direct titration method in the"General Test Methods in Salt Industry-Determination of Iodine"(GB/T 13025.7-2012),and water iodine detection was carried out using the cerium sulfate catalytic spectrophotometry.The test results were evaluated using standard value±uncertainty.Results A total of 146 IDD laboratories in Yunnan Province participated in the external quality control assessment,including 1 at the provincial level,16 at the city(prefecture)level,and 129 at the county level.The feedback rate and qualification rate of urinary iodine,salt iodine in the provincial,city(prefecture)and county level IDD laboratories were all 100%(146/146).The feedback rate and the qualified rate of urinary iodine,salt iodine and water iodine in county level IDD laboratories were all 100%(17/17).Conclusion In 2023,all external quality control assessment results of IDD laboratories in Yunnan Province are qualified,with stable testing quality,providing reliable laboratory technical support for IDD monitoring.
