The determination of protein-bound iodine131 with anion exchange resin column.

Abstract

Abstract A direct comparison of the protein-bound iodine 131 determination by the trichloroacetic acid precipitation technique and the Amberlite anion exchange column procedure was made in 100 consecutive thyroid function studies, and a close agreement between the results of these two methods was established. The simplified and time-saving procedure for the determination of protein-bound iodine 131 , employing an Amberlite anion exchange column, is described.
