PROBLEM TO BE SOLVED: To provide a diagnostic drug using a fluorescent pigment having a high labeling rate to an antibody and large fluorescence intensity. SOLUTION: For this diagnostic drug, the fluorescent pigment having a coloring part comprising an organic EL pigment, and a bonding part bonding to the antibody are used. The labeling rate to the antibody can be improved, in comparison with those hithertofore, and antigen can be detected with high sensitivity by large fluorescence intensity, even in solid state.
