目的:了解贵州省各级疾控机构实验室的川盐检测能力。方法:采用国家碘缺乏病参照室提供的川盐考核盲样对各级疾控机构盐碘检测能力进行考核,用氧化还原法检测,检测结果用(参考值±不确定度)进行评价。结果:省级和7个市(州)级实验室盐碘考核合格,22个县级实验室盐碘考核合格率为63.6%。结论:省级及市(州)级疾控机构川盐检测水平和能力相对稳定,县级疾控机构川盐检测技术需进一步加强。
Objective: To understand the Sichuan Province CDC laboratories at all levels of salt detection capabilities. Methods: The iodine deficiency test reference room provided by the national salt examination of blind samples of disease control agencies at all levels of salt and iodine detection capacity assessment, using the redox test, the test results (reference ± uncertainty) were evaluated. Results: Salt and iodine tests were conducted in provincial and seven city (prefecture) level laboratories, and the pass rate of salt iodine in 22 county-level laboratories was 63.6%. Conclusion: The detection level and capacity of Sichuan salt at provincial and municipal CDC institutions are relatively stable, and the detection technique of Sichuan salt at county CDC needs to be further strengthened.
