目的评价碘实验室检测水平,提高尿碘、盐碘监测资料的准确性和可靠性,为全区持续消除碘缺乏病工作提供质量保障。方法碘盐采用GB/T13025.7-1999中直接滴定法;尿碘采用过硫酸铵消化-砷铈接触法。结果内蒙古地病中心盐碘、尿碘实验室考核合格率100%;盟(市)盐碘实验室考核合格率100%,,盟(市)尿碘实验室考核合格率100%;旗(县)盐碘实验室考核合格率98.99%。结论全区大部分盐碘和尿碘实验室注重日常实验室内部质量控制和管理工作,能严格按照实验室操作规程进行样品检测,检测结果真实、可靠。
Objective To evaluate the detection level of iodine laboratory and improve the accuracy and reliability of urine iodine and iodine monitoring data to provide quality assurance for the continuous elimination of iodine deficiency disorders in the whole region. Methods Iodized salt using direct titration GB / T13025.7-1999; urinary iodine ammonium persulfate digestion - arsenic cerium contact method. Results The rate of salt iodine and urine iodine in the center of Inner Mongolia was 100%. The passing rate of salt iodine laboratory in Union City was 100%, and the passing rate of urine iodine laboratory in Union City was 100%. Flag (County) Salt iodine laboratory test pass rate of 98.99%. Conclusion Most salt iodine and urine iodine laboratories in the region pay attention to routine laboratory internal quality control and management, in strict accordance with laboratory procedures for sample testing, the test results are true and reliable.
