We have been studying a population of 95 normal children aged 10 days to 2 years, in order to determine the normal values of free thyroid hormone in this class of age. The concentrations were measured by radioimmunoassay (Lepetit system). Free T3 (FT3) appears remarkably stable, with a mean at 4,92 pg/ml (3,23 - 7,50 mg/ml at +/- 2SD). These concentrations are significantly higher than those of adult. Free T4 (FT4) shows a significant decrease over the first month of life, with a mean at 14,31 pg/ml (10,27 - 19,94 pg/ml at +/- 2SD). There is no significant variation between the age of one month and 2 years. The mean is 10,51 pg/ml (7,00 - 15,79 pg/ml +/- 2SD).
我们一直在研究95名年龄在10天至2岁的正常儿童群体，以确定这类年龄段游离甲状腺激素的正常值。通过放射免疫分析（莱佩蒂系统）测量浓度。游离三碘甲状腺原氨酸（FT3）表现出显著的稳定性，平均值为4.92皮克/毫升（±2标准差时为3.23 - 7.50微克/毫升）。这些浓度显著高于成年人。游离甲状腺素（FT4）在出生后的第一个月显著下降，平均值为14.31皮克/毫升（±2标准差时为10.27 - 19.94皮克/毫升）。在1个月至2岁之间没有显著变化。平均值为10.51皮克/毫升（±2标准差时为7.00 - 15.79皮克/毫升）。
