IMMUNOCHROMATOGRAPHY METHOD

PROBLEM TO BE SOLVED: To provide an immunochromatography method, capable of measuring both in a low concentration range and in a high concentration range, by substantially widening the specimen measurable range than conventionally. SOLUTION: In the immunochromatography method, a test material, a first labeling material modified by a first bonding material to the test material, and a second labeling material modified by the first bonding material to the test material are mixed and developed on an insoluble carrier in the mixed state; and the test material and the first labeling material and/or the second labeling material are captured, and the test material is detected on a reaction portion, on the insoluble carrier having a material having bonding properties to a second bonding material with respect to the test material or to the first bonding material with respect to the test material. The first labeling material is a labeling material causing an amplification reaction to be generated, and the second labeling material is a labeling material which does not substantially influence the amplification reaction.
