Abstract

Described is a method for determining an analyte in a sample suspected to contain the analyte, by a) contacting the sample with a first and a second capture compound for the analyte, wherein the first and second capture compounds are non-identical capture compounds, and the capture compounds compete in binding to the analyte; b) contacting the capture compounds contacted with the sample with a specifier, wherein the specifier competes in binding to the capture compounds with the analyte; c) determining the amount of complexes having the specifier and a capture compound; and d) determining the analyte in a sample based on the result of step c). Also disclosed is a method for improving the specificity of an indirect immunoassay for determining an analyte, as well as kits, devices, and uses related to the methods.
