<p>An antigen-antibody reaction measurement method using a sandwiching technique has: an antigen-antibody reaction step of binding a solid-phase antibody (32) and a labeled antibody (23) that has an antibody (21) modified by an identification label (22) in a medium containing a sample having an antigen (24), such that the antigen (24) is sandwiched between the solid-phase antibody (32) and the labeled antibody (23); and an antigen concentration measurement step of measuring the concentration of the antigen (24) by way of identifying the identification label (22). Moreover, the method comprises an antigen addition step of adding the antigen (24), so as to increase the antigen concentration, to the sample, which has an antigen concentration which is suitable for antigen (24) concentration measurement in the antigen concentration measurement step, before binding of the antigen (24) contained in the sample with the solid-phase antibody (32) and/or labeled antibody (32) in the antigen-antibody reaction step.</p> |
