[Triiodothyronine radioimmunoassay. Comparison of the different factors between two technics (author's transl)].
Triiodothyronine concentration was determined in human serum and in thyroid extracts by two radioimmunoassay technics. Both antibodies, radioactive T3, stable T3, protein-binding-hormone inhibitors, methods used to separate the free from the bound fractions were different. Each factor from a method was substituted to the homologue of the other method. The results occasionally showed a variation of 32 p. cent in the first method and 50 p. cent in the second one. However the results gave a correct interpretation of the triiodothyronine values measured in human serum and in thyroid extracts.
