碘缺乏病病因清楚,防治方法主要是全民食用合格碘盐,确保碘盐合格的前提是认真做好碘盐监督(测)工作。目前,《全国碘缺乏病防治监测方案》规定销售单位、居民用户的碘盐仍用半定量检测方法,由于碘盐监督(测)已纳入了法制管理,所以,碘盐半定量检测方法在全国已完成了它的“历史使命”,应尽快地用全定量检测方法取而代之。笔者就两种碘盐检测方法进行剖析,供各级领导决策和同仁们进行碘盐监督(测)时参考。1 碘盐半定量检测方法系统误差大1.1 半定量检测方法灵敏度差 按照《碘盐半定量检测质量评定标准(试行)》规定,其灵敏度大部分达不到5mg/kg,与全定量检测方法相比,其测得值往往相差5mg/kg以上。1.2 半定量检查方法结果判定有很大随意性
The cause of iodine deficiency disease is clear, the prevention and treatment method is mainly the national consumption of qualified iodized salt, iodized salt to ensure that the premise is to do a good job iodine salt supervision (measurement) work. At present, the “National Iodine Deficiency Disease Prevention and Control Monitoring Program” stipulates that semi-quantitative detection methods for iodized salt are still used in sales units and residential users. Since iodine salt monitoring (measurement) has been incorporated into legal management, semi-quantitative detection of iodized salt Has completed its “historic mission” and should replace it with a full quantitative test as soon as possible. I analyzed the two methods of iodized salt detection for decision-making leaders at all levels and colleagues for iodized salt monitoring (measuring) reference. 1 semi-quantitative detection of iodized salt system error 1.1 semi-quantitative detection of poor sensitivity in accordance with the “semi-quantitative detection of iodized salt quality assessment standards (Trial)” most of its sensitivity less than 5mg / kg, and the full quantitative detection methods Ratio, the measured value is often a difference of 5mg / kg or more. 1.2 semi-quantitative test results to determine a lot of randomness
