Abstract:
1. A chromatography measuring method comprising: providing a biosensor having developing said test sample on said development portion; using an optical detector to measure in an area between said first and second parts of said development portion that does not include said second part of said development portion, an amount of said label reagent eluted from said first part of said development portion; using an optical detector to measure, in said second part of said development portion, an amount of any label reagent bound to said immobilized reagent in said second part of said development portion; correcting the measured amount of said label reagent bound to said immobilized reagent in said second part of said development portion, on the basis of a relationship between the measured amount of said label reagent eluted from the first part of said development portion and a total amount of said label reagent present in said first part of said development portion before application of said test sample; and calculating a concentration of said analyte in said test sample on the basis of the corrected amount of said label reagent bound to said immobilized reagent in said second part of said development portion.
