Abstract
An object is to provide an immunochromatography detection method and an immunochromatography kit in which a prozone phenomenon occurring in a sandwich method when using an analyte in which an antigen is present in a large excess amount is suppressed/excluded. The object was achieved by retaining a nonionic and hydrophilic surfactant having an HLB value of 13 to 18 in a sample addition part of an immunochromatography device, and also using a membrane having a fast flow speed as a membrane to be used for a chromatograph medium.
