1. An immunoassay method for free apoptosis inhibitor of macrophage (AIM) in a biological sample containing complex AIM and free AIM, the method comprising:
bringing the biological sample into contact with an antibody specifically reacting with free AIM or a fragment thereof having antigen-antibody reaction activity with free AIM in a presence of an added anti-IgM antibody or a fragment thereof having an antigen-antibody reaction activity with IgM, wherein the added anti-IgM antibody or fragment thereof is present in an amount that suppresses non-specific reactions of the antibody specifically reacting with free AIM.
