1. A specific coupling reaction measuring method for measuring a plurality of subject substances in a sample, comprising the steps of:
- (a) constructing a reaction system including said sample and magnetic particles on which a specific coupling substance for specifically coupling with a first subject substance is immobilized;
(b) measuring an optical characteristic of said reaction system;
(c) after the step (b), removing, from said reaction system, an agglutination complex including said subject substance, said specific coupling substance and said magnetic particles by utilizing magnetic force;
(d) after the step (c), adding to said reaction system, which includes said sample, another specific coupling substance for specifically coupling with another subject substance;
wherein said another specific coupling substance includes an antigen or antibody for specifically coupling with said another subject substance; and
(e) measuring the optical characteristic of said reaction system after the step (d).
