应用免疫放射测定法(IRMA)作纸片血斑促甲状腺素(TSH)测定,对不同层次人群的TSH水平进行测定。结果:(1)胎儿及新生儿组TSH值<5mIU/L者分别占68.4％和61.1％。其他各组(<1岁婴儿、7～14岁学生、孕妇A、孕妇B、育龄妇女和成人)TSH值<5mIU/L者占96.7％～100％,分别与胎儿及新生儿组比较,差异有极显著性(P<0.01)。(2)7～14岁学生、孕妇B、成人及育龄妇女的尿碘值≥100μg/L者分别为56.1％,53.2％,58.9％和52.2％。(3)居民盐碘含量<20ppm者占97.6％,提示该地区存在碘缺乏,以致胎儿及新生儿组TSH值向高值偏移,新生儿为监测碘缺乏唯一理想的人群。
The levels of TSH in different levels of the population were determined by immunoradiometric assay (IRMA). Results: (1) The fetus and newborn group with TSH <5mIU / L accounted for 68.4% and 61.1% respectively. The other groups (<1-year-old infants, 7-14-year-old students, pregnant women A, pregnant women B, women of childbearing age and adults) accounted for 96.7% -100% of children with TSH <5mIU / L, Significantly (P <0.01). (2) 56.1%, 53.2%, 58.9% and 52.2% of urinary iodine values ≥100μg / L for students aged 7-14 years, pregnant women B, adults and women of childbearing age. (3) Residents salt iodine content of <20ppm accounted for 97.6%, suggesting the existence of iodine deficiency in the region, resulting in TSH values of fetuses and neonates shift to high values, the neonatal monitoring iodine deficiency is the only ideal population.
