Abstract

Methods for enhancement in accuracy of immunochemical analysis of heterogeneous biological fluids containing exogenous substances that can interfere in immunochemical analysis for endogenous analytes of interest. According to this method a heterogeneous biological fluid sample is pretreated with an interferant suppression effective amount of a molybdenum coordination complex, so as to reduce manifestation of the presence of said exogenous material under immunoassay conditions. This invention is suitable for the suppression of manifestation of exogenous substances, specifically metabolites of drugs of abuse, during the immunoassay of biological fluids of infants for detection of endogenous substances indicative of a wellness or disease state. This invention also has application for similar suppression exogenous substances in the biological fluid of adults that have been inadvertently exposed to such substances (e.g. secondhand smoke).
