Abstract
Method and apparatus for detecting immunological agglutinating reaction comprises steps of measuring light absorptions of a liquid medium with antibody before and after antigen-antibody reaction by using a light which is absorbable by the antibody, and calculating the difference of the light absorptions, for determining the presence or absence of the agglutination based on the fact that the agglutinating reaction reduces the concentration of the antibody affecting the light absorption of the liquid medium. The apparatus includes a turntable, two photometers, sample and reagent handling means and calculator.
