ABSTRACT:
Automatic particle pattern judging method, in which particles to be tested, such as blood cell particles, are delivered into not only a reaction vessel but also a reference vessel, and an amount of the particles delivered into the reference vessel is measured and a judgement whether the particle pattern formed in the reaction vessel is agglutinated or not is conducted by correcting values of a reaction liquid contained in the reaction vessel concerning parameters for the judgement or correcting threshold values, with which the values of the test liquid concerning the parameters should be compared in accordance with the amount of the particles delivered into the reference vessel. Therefore, by the method according to the invention, even when the amount of particles to be tested delivered into the reaction vessel is varied for some reason, it is possible to judge correctly whether the particle pattern is agglutinated or not.
