Abstract: The assay apparatus includes a loading part into which a cartridge including a carrier and a case is attachably and detachably to be loaded, the carrier having an assay region in which a color development state changes depending on whether the sample is positive or negative, and an index region which is optically distinguishable from other regions regardless of whether a sample is positive or negative, the case accommodating the carrier; a light source that illuminates the observation region on the carrier including the assay region and the index region; an imaging unit that images the observation region; and a processor configured to acquire an image including the observation region from the imaging unit, detect a position of the index region from the acquired image, and specify a position of the assay region with reference to the detected position of the index region.
