Abstract
Novel binding assay techniques have been developed which improve accuracy and sensitivity via accounting for interfering factors. They rely on use, in a simultaneous incubation, of two or more different labels, some of which are used primarily to detect analyte, and others to detect interfering substances originating in the sample. The mathematical relationships between the labels allow corrections that lead to more accurate and sensitive determination of the presence and concentration of the analyte.
