[Normal values for circulating thyroid hormones, T3 uptake and thyrotropin before and after TRH. Radioimmunoassay determinations on 182 euthyroid children (author's transl)].
Measurements of T4, T3, rT3, T3U, and TSH (before and after TRH stimulation) were performed by RIA. 182 children, apparently euthyroid, age 2/12--14 years, were investigated in a cross sectional study. Free T4RIA and free T3RIA Indices and the ratio rT3/T3 and T4/T3 were calculated. Statistical analysis showed the following results: 1. Geometric mean serum concentrations of T4, T3, rT3 and TSH (basal) show no age related differences; T4 showed a not significant negative slope with age.--2. The ratio rT3/T3 and T4/T3 remains constant.--3. TRH induced TSH release (indicating the activity of the regulatory system) is unchanged from 2/12 to 14 years. Geometric means values, standard deviations and normal ranges are given.
