ABSTRACT:
A object of the present invention is to provide an immunochromatography method that makes it possible to rapidly detect an ultratrace amount of an analyte that has been impossible to analyze by conventional immunochromatography methods. The present invention provides an immunochromatography method, which comprises developing an analyte and a labeling substance which is modified with a first binding substance against the analyte in a mixed state on a porous carrier and capturing the analyte and the label at a reaction site on the porous carrier having a second binding substance against the analyte or a substance capable of binding to the first binding substance against the analyte, so as to detect the analyte, wherein the labeling substance having an average particle size of 1 μm or more and 20 μm or less is detected.
