Abstract: The invention provides an assay method for an assay system using an anti-immunocomplex antibody, which is able to increase reaction efficiency. The n immunoassay method uses: an anti-hapten rabbit monoclonal antibody immobilized on a water-insoluble carrier, and a labeled anti-immunocomplex antibody, wherein the method comprises the following steps (i) to (iii): (i) a step of reacting the anti-hapten rabbit monoclonal antibody immobilized on the water-insoluble carrier with a hapten in a solution to be measured, (ii) a step of reacting the labeled anti-immunocomplex antibody with the hapten-anti-hapten rabbit monoclonal antibody immune complex, and (iii) a step of detecting the signal from the label.
