Abstract
A sample and a reagent are delivered into a reaction vessel having a plurality of inclined bottom surface portions, inclination angles of these portions being increased in a step-wise manner. The reaction vessel is kept still for such a time period that particles descend on the bottom surface portions to from particle patterns. The particle patterns thus formed on respective bottom surface portions are separately detected to produce agglutination and non-agglutination signals. The antigen-antibody reaction is judged in accordance with the agglutination and non-agglutination signals.
