摘　　要：目的分析青海省碘缺乏病实验室尿碘、盐碘及水碘外质控考核情况,评价省、市、县各级实验室检测能力及外质控网络运行情况,为巩固和消除碘缺乏病提供质量保障。方法2021年,青海省1个省级、8个市级、43个县级实验室参加尿碘、盐碘考核,1个省级和8个市级实验室参加水碘考核。采用外质控考核样品的参考值±不确定度的方法对检测结果进行评价。结果参加各项考核的所有实验室均反馈。1个省级实验室尿碘、盐碘、水碘考核均合格。8个市级实验室,有2个实验室尿碘考核不合格,合格率为6/8;盐碘和水碘考核均合格。43个县级实验室,有7个实验室尿碘考核不合格,合格率为83.7%(36/43);盐碘考核均合格。结论青海省碘缺乏病实验室外质控网络已全面覆盖到所有市和县级实验室。省级实验室各项检测能力稳定,保持较高水平;个别市、县级实验室的检测质量还不稳定,需进一步加强。Objective To analyze the external quality control assessment results of urinary iodine,salt iodine and water iodine in iodine deficiency disorders laboratories in Qinghai Province,to evaluate the testing capacity of provincial,municipal and county-level laboratories and the operation of external quality control network,so as to provide quality assurance for consolidating and eliminating iodine deficiency disorders.Methods In 2021,1 provincial,8 municipal,and 43 county-level laboratories in Qinghai Province had participated in the assessment of urinary iodine and salt iodine,while 1 provincial and 8 municipal-level laboratories had participated in the assessment of water iodine.The assessment results were evaluated using the method of reference value±uncertainty of external quality control samples.Results All laboratories that participated in the assessment had provided feedback.One provincial-level laboratory passed the assessment of urinary iodine,salt iodine,and water iodine.Among 8 municipal-level laboratories,2 laboratories failed the urinary iodine assessment,with a pass rate of 6/8;the assessment of salt iodine and water iodine in 8 laboratories were all qualified.Among 43 county-level laboratories,7 laboratories failed the urinary iodine assessment,with a pass rate of 83.7%(36/43);the assessment of salt iodine in 43 laboratories were all qualified.Conclusions The external quality control network of iodine deficiency disorders laboratories in Qinghai Province has fully covered all municipal and county-level laboratories.The testing capability of provincial-level laboratory is stable and maintains a high level;the testing quality of some municipal and county-level laboratories is still unstable and needs to be further strengthened.
