[In vitro tests as a tool for examination of the thyroid function in childhood and newborn stage (author's transl)].
The concentration of hormone iodine, total thyroxine and the T3-test were determined in children from the newborn-period until school-age. Hormone iodine and total thyroxine increased markedly from day 1 to 6 of life and decreased after day 21. This decrease continued until preschool-age. The T3-value was highest in the newborns and showed no significant changes during the following ages. The higher blood levels of thyroid hormone in infants during the neonate period have to be taken into account when distinguishing between hypo- and hyperthyroid patients.
