Abstract
A problem to be solved by the present invention is to inhibit a nonspecific agglutination reaction in an agglutination test using a monoclonal antibody having a property of specifically biding to PIVKA-II and a monoclonal antibody having a property of specifically biding to prothrombin as well as two types of carrier particles carrying these monoclonal antibodies. The nonspecific agglutination reaction can be inhibited by adding certain divalent metal ions to a reaction solution containing the monoclonal antibody having a property of specifically biding to PIVKA-II and the monoclonal antibody having a property of specifically biding to prothrombin as well as the two types of carrier particles carrying these monoclonal antibodies.
