Abstract
A reaction vessel having a ring-shaped flat bottom portion and a conically inclined bottom portion is used to detect a particle agglutination reaction. Image of particle patterns formed on the flat bottom portion, middle and lowermost portion of the inclined bottom portion are separately detected by first, second and third light receiving elements to produce first, second and third signals. When the first signal is within a predetermined standard range, the particle agglutination reaction is judged by comparing a difference between the second and third signals with a predetermined upper and lower standard values. Contrary to this, when the first signal is beyond the predetermined range, the judgement for the agglutination reaction is not effected.
