Abstract
An assay for detecting the presence and amount of a hormone in culture media or a biological sample includes the steps of preincubating two antibodies specific for the hormone to be assayed in a preincubation medium that is essentially free of the hormone to be detected, contacting a sample to be tested with the preincubated antibodies, and detecting hormone-antibody complexes formed in the contacting step. This assay reduces or eliminates non-specific interference and thereby increases the sensitivity of the assay.
