Abstract
Composition and method are provided for the pretreatment of serum prior to a thyroxine assay. Prior to carrying out of the assay, particularly an immunoassay or competitive protein-binding assay, the serum sample is combined with cyclodextrin preferably in combination with an hydroxylated aromatic carboxylic acid in a basic medium, in amounts sufficient to minimize interference with obtaining an accurate and reliable determination of polyiodothyronine in the serum. Normally, after the reagents have been added to the serum, a small incubation period is allowed, after which time the additional reagents may be added for carrying out the assay.
