用青海省地方病防治研究所ＤＹＪ－４型碘盐半定量检测包对青海省２３个县区的１１０６份加碘盐样做半定量测定的同时用直接滴定法做全定量测定进行对比分析。两方法测定结果比较，除化隆县有显著差异外，其余均无显著性差异（Ｐ＞０．０５）。表明该碘盐检测包在全定量检测尚不具备的地区及现场应用时，具有全定量的检测效果
Using the DYJ-4 type iodine salt semi-quantitative detection kit of Qinghai Institute of Endemic Diseases Control and Prevention, 1106 iodized salt samples from 23 counties of Qinghai Province were semi-quantitatively determined and compared with the direct quantitative titration. There was no significant difference between the two methods (P> 0.05) except that there were significant differences in Hualong County. Indicating that the iodized salt detection package in the full quantitative detection is not available in the area and on-site applications, with a full quantitative test results
