Patent ID: 8110406

Claim:
A method for analyzing a specimen by an immunoassay process, comprising: obtaining a supporting body comprising a test line having a capturing antibody or capturing antigen adapted to be specifically combined with the specimen, and a marker substance possessing a sensitizing action and coexisting with the capturing antibody in case of using the capturing antibody or with the capturing antigen in case of using the capturing antigen, providing a complex material including the specimen and a labeled antibody specifically combining with the specimen and forming another marker substance, to the test line of the supporting body, capturing the specimen of the complex material by the test line to thereby accumulate the labeled antibody on the test line so that a color development or light emission obtained by the marker substance on the test line is added with a color development or light emission originating from the another marker substance forming the labeled antibody to thereby increase the color development or light emission originating from the labeled antibody accumulated on the test line, and detecting the increased color development or light emission obtained by the test line to analyze the specimen.
