Abstract
A method of assaying a sample with the use of the aggregation reaction of immunological microparticles and an assay kit. The assay is conducted by using microparticles wherein the same or an analog of the analyte and a substance that specifically binds to a substance that can specifically bind to the analyte are both bound to an insoluble carrier. Thus, it becomes possible to conveniently carry out the assay even in the case where the analyte has only a small number of specific binding sites, without especially adding a competitive substance carrying hapten bonded thereto to the reaction system so as to induce simultaneous competition of the target substance and the competitive substance.
