Abstract
Abstract The ability of serum to bind additional triiodothyronine is determined by a method requiring minimal quantities of serum, of the order of 0.10 ml., and short mixing times, of the order of 40 minutes, by employment of a specially designed syringe-type reaction vial in which radioactive triiodothyronine and a buffer are prepackaged, and a resin membrane separable from the liquid reactants by syringing of the latter from the vial after mixing.
