SERUM THYROGLOBULIN CONCENTRATIONS IN INFANTS OF VARIOUS MATURITY

A few studies have suggested that s-thyroglobulin (Tg) in cord blood is higher in premature (PT) than in fullterm (FT) babies. S-Tg was determined by RIA in 33 routinely sampled blood from 33 infants. S-Tg ranged from 2.5-148 ug/l, median 33 ug/l, signficantly higher than in adults (p < 0.001). Subsequently, detailed informations on s-Tg, T4, T3, TSH, and thyroid hormone-binding proteins TBG, TBPA, and albumin were conducted in 14 FT, in 6...
