山东省2001年县级盐碘实验室质量控制分析

为了解山东省县级盐碘实验室检测能力，采有直接滴定法对全省30个县级盐碘实验室进行质量控制评估，结果有29个实验室测定结果在质控范围占96．7％，1个实验室测定结果超出质控范围占3．3％，绝大多数实验室测定结果的准确度较高，可比性较强。实验室整体检测水平较高，建议扩大考核范围，进一步提高全省各盐碘实验室的检测水平。

Analysis of the Quality Control at Labs of Salt Iodine at County Level in Shandong Province in 2001

To master the measuring capacity of salt iodine at labs at county level in Shandong Province and intensify the quality intention of measurers, 30 labs were evaluated on quality control. Measuring the salt iodine quality control samples with the method of direct titration, we appraised the accuracy and comparability of the results. 29 lab results were within the quality control range, taking 96.7%, 1 labs out of the quality control range, taking 3.3%. The accuracy and comparability of the most labs' results were rather good. The measuring capacity of county salt iodine labs was higher. In order to make further improvement on the measuring quality of all salt iodine labs in Shandong, it was suggested that the quality control range be enlarged.
