为探讨Ｔｇ在ＩＤＤ研究中的价值，利用两种Ｔｇ药盒（下称Ｔｇ〈Ａ法〉和Ｔｇ〈Ｂ法〉）对相同对象同时测定进行比较。观察对象为长期供碘盐的大别山区霍山县太平畈乡小学和未补碘地区合肥市小学８～１０岁儿童。结果表明大别山组儿童尿碘、血清ＦＴ３、ＦＴ４值均显著高于合肥市组儿童（０．０００５＜Ｐ＜０．０５），Ｔｇ〈Ａ法〉结果与ＴＳＨ值显著低于合肥市组（０．００１＜Ｐ＜０．０５），但Ｔｇ〈Ｂ法〉结果与ＴＳＨ及Ｔ〈Ａ法〉结果相反。两法测定结果无相关性（Ｐ＞０．０５）。Ｔｇ〈Ａ法〉结果与尿碘水平ＴＳＨ值均有显著直线相关关系（Ｐ＜０．００１），而Ｔｇ〈Ｂ法〉结果无上述规律。结论是Ｔｇ在评价碘营养状态时比ＴＳＨ更敏感，药盒的选择是保证结果一致性的关键。
To explore the value of Tg in IDD studies, simultaneous determination of the same subjects was performed using two Tg kits (hereinafter referred to as Tg and Tg ). Observe the long-term iodized salt in the Taoshan District Huoshan County Taiping Township primary school and non-iodine-rich Hefei primary school children aged 8 to 10 years. The results showed that the urinary iodine, serum FT3 and FT4 levels in children in Dabieshan group were significantly higher than those in Hefei group (0.0005
