Abstract
An agglutination analyzing vessel for use in an immunological agglutination reaction in which there is provided a liquid-absorbable member made of porous material in at least a portion of an inclined bottom surface of a well provided in the analyzing vessel. A solution for a test liquid is absorbed into the liquid-absorbable member to cause a liquid flow directed downwardly in the test liquid. This downward liquid flow promotes the sedimentation of particles. Thus, both agglutination and non-agglutination particle patterns can be formed on the bottom surface of the vessel within a short time period.
