Most c 251-labelledthe serum of patients is incubated with 1 yroid T3 which occupies binding sites on the t not hormone binding proteins, mainly TBG der is left already occupied by T4, while the remai fractions in solution. The protein-bound and free ich the are separated by addition of a resin, to w ee to free hormone binds. The proportion of 1 to the protein-bound 1251-T3 is inversely relate hyroid residual unoccupied binding capacity of y related to hormone binding proteins, and is direct free hormone fractions.
