Test for assessing the unsaturated binding capacity of serum proteins which bind thyroid hormones
First Claim
1. In a test for assessing the unsaturated binding capacity of serum proteins which bind thyroid hormones and in which a radioactive thyroid hormone is admixed with a serum sample, free radioactive hormone is adsorbed by a sorbent added to the mixture, the adsorbed and non-adsorbed fractions are separated, and the radioactivity of the adsorbed or non-adsorbed fraction is determined, the improvement wherein the sorbent comprises a montmorillonite-ammonium complex.

Abstract
An improved test for assessing the unsaturated binding capacity of serum proteins which bind thyroid hormones employs a clay-organic complex for adsorbing a free radioactive hormone fraction. The sorbent, an organically modified montmorillonite, provides better separation of thyroid states and may be employed in smaller amounts than prior sorbents employed in comparable tests.
