Abstract

An assay for determining the presence of an analyte of interest in a test sample containing an interfering substance that interferes with the assay is disclosed. The assay comprises the steps of forming a reaction mixture by combining in an assay medium (i) an assay system containing components for detecting the analyte of interest, (ii) a test sample containing the analyte and an interfering substance, and (iii) an additional amount of the interfering substance in a quantity sufficient to substantially mask the effect of the interfering substance in the test sample. This reaction mixture is incubated under conditions sufficient to allow complex formation. This resultant complex formation is detected and the presence of the analyte in the test sample is determined.
