Abstract
A humoral testing apparatus in which a measuring light is irradiated to a reagent area forming a color as a result of a reaction and an optical density of the reagent area is detected by a detecting operation of light intensity of the reflected light. The humoral testing apparatus enables a humoral test to be performed accurately in cases where nonuniformity occurs with the reaction of a reagent with a humoral sample within the reagent area, or in cases where fine dust is present within each detecting spot in the reagent areas. The light reflected from the reagent areas is detected with a two-dimensional photodetector. The independent light intensity detecting operations are performed with respect to the subareas of the reagent area of a reagent layer. A photo detection signal S, which represents the intensity of the reflected light is statistically processed with a signal processing section 51.
