RAPID EXTRACTION METHOD FOR SERUM THYROXINE

摘要

A method for determining total thyroxine by the competitive protein binding analysis procedure and in which an acid buffer is employed to liberate the bond thyroxine from the serum proteins to make the thyroxine available for competitive binding. The buffer greatly reduces extraction time in comparison to the use of alcohol, conventionally used in such procedures, and comprises a glutamate - salicylate mixture.
