Analyzing apparatus and method for immunological agglutination reactions

摘要

An apparatus for analyzing blood samples by detecting particle agglutination patterns formed on inclined bottom surfaces of reaction vessels formed in a microplate includes a diluted sample preparing section for delivering given amounts of blood cells and serum contained in a sample tube into diluting vessels mounted on a sample plate secured on a rotating endless belt and for discharging predetermined amount of a diluent into the diluting vessels to form diluted blood cell and serum samples, a diluted sample delivering section for delivering given amounts of the diluted blood cell and serum samples contained in the diluting vessels into an array of reaction vessels of the microplate in a selective manner according to test-items to be analyzed and a reagent delivering section for discharging given reagents into the reaction vessels. The microplate having the diluted blood cell and serum samples delivered therein is fed in a substantially stationary manner along a reaction line arranged in a vertical plane and in this reaction line the particle patterns formed on the reaction vessel bottoms are photoelectrically detected.
