Abstract: Using two types of antibodies, i.e., a first antibody having a higher affinity for a target substance than for a competitive substance and a second antibody having a higher affinity for the competitive substance than for the target substance, a specimen is treated with these two antibodies. Then, the competitive substance in the specimen first binds to the second antibody and thus the ratio of the target substance to the competitive substance in the specimen is enlarged. As a result, the target substance becomes liable to bind to the first antibody and, in its turn, the reactivity of the target substance is elevated compared with the case of using the first antibody alone. Thus, the target substance in the specimen can be accurately assayed while avoiding the effects of the competitive substance contained in the specimen.
