目的通过回顾11年四川省碘缺乏病实验室质控网络运行情况,总结质控工作存在的不足,进一步加强实验室质控,保证碘缺乏病防治监测的质量。方法对2000-2010年全省各级碘缺乏病实验室参加外部质控考核结果进行统计分析。结果 11年来四川省级实验室盐碘和尿碘的考核结果均为合格,尿碘的Z分值|Z间|和|Z内|均≤2。市州级实验室盐碘考核合格率为87.5%～100%,尿碘考核合格率为93.3%～100%,尿碘的|Z间|≤2占97.2%,2<|Z间|<3占2.8%,|Z间|≥3占0%。,|Z内|≤2占94.4%,2<|Z内|<3占3.9%,|Z内|≥3占1.7%。区县级实验室盐碘考核合格率为86.1%～100%。结论四川省碘缺乏病实验室质控网络已全面覆盖到全省所有市州和区县实验室,各级实验室的盐碘和尿碘检测能力保持在较高的水平。
Objective By reviewing the operation of quality control network of iodine deficiency disorders laboratory in Sichuan Province in the past 11 years and summarizing the shortcomings in quality control work, the quality control of laboratories is further strengthened to ensure the quality of prevention and control of iodine deficiency disorders. Methods Statistical analysis was conducted on the results of external quality control examination conducted by laboratories at all levels of iodine deficiency disorders in 2000-2010 in our province. Results The assessment results of salt iodine and urinary iodine in Sichuan provincial laboratories for the past 11 years were all qualified. The Z scores of urine iodine | Z | and | Z | State-level laboratory salt iodine test pass rate of 87.5% to 100%, urinary iodine test pass rate of 93.3% to 100%, urine iodine | Z | | 2 accounted for 97.2%, 2 <| Z between | Accounting for 2.8%, | Z between | ≥ 3 accounted for 0%. , | Z within | 2 accounted for 94.4%, 2 <| Z within | 3 accounted for 3.9%, | Z within | 3 accounted for 1.7%. District county lab salt iodine assessment pass rate of 86.1% to 100%. Conclusion The laboratory quality control network of Iodine Deficiency Disorders in Sichuan Province has covered the laboratory of all cities, prefectures and counties throughout the province and the detection ability of salt iodine and urinary iodine at all levels of laboratory has been kept at a high level.
