Colloidal Gold Monoclonal Antigen, Antibody Competitive Immunity Principle. When the specimen contains morphine or its metabolite at a concentration of 300 ng / ml, it binds to a limited antibody with a chromogenic microparticle immobilized on the permeable membrane, thereby preventing its binding to the antigen in the test area (T line area) , T zone will not appear precipitation ribbon. If there is no drug or its metabolites in the specimen, there will be a ribbon in the T zone. Enzymatic Solvent Leaching Extraction Another strip (C-line) is used to determine if the experiment is reliable.
