[Reference values for the concentration of free thyroxine and free triiodothyronine in the serum of euthyroid children].

Concentrations of free thyroxine (n = 341, male = 205, female = 136) and free triiodothyronine (n = 318, male = 198, female = 120) were determined using the radioimmunoassay method in blood serum of euthyroid children. Beyond the 30. day of life no significant differences were found in different age groups for the free thyroxine and free triiodothyronine concentration. The free thyroxine values of the infants in the range of 16.5-19.5 pg/ml decreased after the 30. day of life to the range of 15-17.5 pg/ml. In opposition to this trend free triiodothyronine values increased after the 30. day of life from the range of 2.5-3.3 pg/ml up to the range of 4.7-5.5 pg/ml.

[Comparison of the luminescence enhanced enzyme immunoassay Amerlite FT4/MAB-FT4 and Amerlite FT3/MAB-FT3 in blood serum of children. Reference values].

Concentrations of free thyroxine (n = 225, male = 124, female = 101) and free triiodothyronine (n = 60, male = 35, female = 25) were determined using the luminescence enhanced enzyme immunoassay methods Amerlite FT4/MAB-FT4 and Amerlite FT3/MAB-FT3 in blood-serum of children. In contrast to the excellent agreement of the results between the Amerlite FT4 and MAB-FT4 method, a significant difference was found between the Amerlite FT3 and MAB-FT3 results. Therefore it was necessary to establish new reference ranges for the MAB-FT3 method in childhood (cord blood = 50, n = 272, male = 183, female = 89).
