Abstract
The present invention relates to an immunoreaction measuring method for measuring an antigen or antibody contained as a subject substance in a sample, wherein the sample was mixed with at least one compound selected from the group consisting of dicarboxylic acids having a hydroxyl group, dicarboxylic acids having a double bond, straight-chain dicarboxylic acids expressed by the chemical formula (1): HOOC(CH)COOH (n is an integer), and the salts of these dicarboxylic acids, and an antibody or antigen as a specifically binding substance capable of specifically binding to the subject substance, to obtain an acidic reaction solution, and then an antigen-antibody complex, generated by an antigen-antibody reaction of the subject substance with the specifically binding substance in the reaction solution was detected. This makes it possible to improve a measurement value and to relax a limitation of a measurement range due to a zone phenomenon that occurs in an antigen-excess region.
