A plurality of different kinds of reagents are supported at different positions on a reagent layer. A humoral testing apparatus irradiates measuring light which has a wavelength adapted to one of the plurality of the reagent areas which forms a color, and detects the intensity of the light reflected from the reagent areas with the photodetector with respect to each of the reagents, and thus detects the optical densities of the reagent areas.
