Abstract: PURPOSE:To make clear an agglutination transit image by mixing a microcapsule reagent with a relatively high specific gravity and a microcapsule reagent with a relatively low specific gravity to be used for the antigen-antibody reaction. CONSTITUTION:A microcapsule reagent comprises microcapsules with a high specific gravity d2 and microcapsules with a low specific gravity d1.

In the antigen-antibody reaction using the microcapsule reagent, an agglutination image is formed by a microcapsule with the specific gravity d1 to fill the gap of a coarse agglutination image formed by the microcapsule reagent with the specific gravity d2. Thus, a clear and sharp agglutination image is obtained without roughness.
