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