ABSTRACT:
An automatic analysis apparatus and an automatic analysis method analysis that includes an optical convergence point adjusting unit in order to variably adjust an optical convergence point of irradiation light or an optical convergence point of detection light to or from a reaction cuvette in accordance with at least one of analysis conditions of a kind of reaction of a mixed solution contained in the reaction cuvette, a liquid volume of the mixed solution or a measurement wave length. The optical convergence point adjusting unit is provided in front the reaction cuvette, in back of the reaction cuvette, or both in order to variably control the position of an optical convergence point so as to maximize the irradiation light based on the volume of the mixed solution in the reaction cuvette. By variably controlling the convergence point of the optical convergence point adjusting unit based on each of the examination items, both measurements of a turbidimetric assay and a spectrophotometric assay can be performed in a single automatic analysis apparatus with good accuracy and precision.
