【摘要】：目的考核各级尿碘实验室的检测能力及其持续性,了解各省实验室外质控网络的管理和运行情况。方法采用Z比评分法进行检测结果的统计学评价,Z分值的公议值来自所有省级和地市级实验室。结果参加能力验证的32个省级单位的尿碘实验室全部反馈了质控结果并通过了能力验证;343个地市级尿碘实验室的反馈率为99.4%,合格率为98.3%;485个县级尿碘实验室通过了能力验证。结论全国省级实验室的检测结果非常接近,实验室内和实验室间变异很小,检测精密度和准确度均保持了较高的水平,采用参考值和不确定度评价方法,其结果基本上与Z分值评价法相符;大部分地市级实验室的尿碘检测能力保持了较高的水平;485个县级实验室参加并通过了能力验证;建议各级实验室要常规进行内部质量控制和常规使用标准物质,并通过参加能力验证使检测质量得到持续提高。
[Abstract]:Objective to evaluate the ability and persistence of urinary iodine laboratories at all levels. To understand the management and operation of the external quality control network in laboratories in various provinces. Methods the statistical evaluation of the test results by Z ratio scoring method was carried out. The common value of Z score came from all provincial and municipal laboratories. The quality control results of urine iodine laboratories in 32 provincial units were all feedback and the feedback rate of 343 municipal urine iodine laboratories was 99.4. The qualified rate was 98.33% and 485 county-level urine iodine laboratories passed the capacity verification. The results of testing in provincial laboratories across the country are very close. The variation in laboratory and between laboratories is very small, and the precision and accuracy of detection have kept a high level. The evaluation method of reference value and uncertainty is adopted, and the result is basically consistent with the evaluation method of Z score. The capacity of urine iodine detection in most prefectural and municipal laboratories has maintained a relatively high level. 485 county-level laboratories have participated and passed the capacity verification. It is suggested that laboratories at all levels should routinely carry out internal quality control and the routine use of standard substances. The quality of the test is continuously improved by participating in the ability verification.
