Provided are an analysis device, an analysis method, and the like that predict a concentration even for a sample having high concentration that can be outside a measurement range as it is, using an absorbance measurement result in a reaction course at the time of measurement of a test liquid containing an immunological reagent and the sample, and determine an optimum dilution rate to conduct measurement. As the present invention, for example, an analysis device having means (A) that detects a prozone during measurement of a sample, and means (B) that determines a high concentration region by automatically determining a dilution rate of the test liquid can be recited.
