A biochemical analysis data producing method includes the steps of irradiating a stimulable phosphor sheet including a support formed with a plurality of stimulable phosphor layer regions spaced apart from each other with light emitted from a standard light source or radiation emitted from a standard radiation source to expose the plurality of stimulable phosphor layer regions, irradiating the plurality of stimulable phosphor layer regions with a stimulating ray to excite stimulable phosphor contained in the plurality of stimulable phosphor layer regions, photoelectrically detecting stimulated emission released from the plurality of stimulable phosphor layer regions to produce correction data for the individual stimulable phosphor layer regions, superposing the stimulable phosphor sheet on a biochemical analysis unit including a plurality of spot-like regions formed in the same pattern as that of the plurality of stimulable phosphor layer regions of the stimulable phosphor sheet and selectively containing a radioactive labeling substance, exposing the plurality of stimulable phosphor layer regions to the radioactive labeling substance selectively contained in the plurality of spot-like regions, scanning the plurality of stimulable phosphor layer regions with a stimulating ray to excite stimulable phosphor, photoelectrically detecting stimulated emission released from the plurality of stimulable phosphor layer regions to produce biochemical analysis data, and correcting the thus produced biochemical analysis data using the correction data for the individual stimulable phosphor layer regions. According to this biochemical analysis data producing method, it is possible to produce biochemical analysis data having excellent quantitative characteristics with high resolution even in the case of forming at a high density in the biochemical analysis unit spot-like regions that are selectively labeled by specifically binding a substance derived from a living organism labeled with a radioactive labeling substance with specific binding substances.
