Abstract

Improved competitive binding thyroid hormone assay in which thyroid hormone bound by thyroid binding protein is separated from free thyroid hormone by removal with an intermediate base anion exchange resin. Typical are resins characterized by having an aliphatic lattice, particularly, a polyalkyleneamine lattice having tertiary and quaternary amine groups. The resin is advantageously added for the separation function in tablet form.
