In this study, colloidal gold monoclonal antigens, immune competition principle. When the sample contains morphine or its metabolites in the content of 300ng / ml, that is fixed with the membrane attached to the small particles with the color of the limited antibody binding to prevent the test area (T line area) antigen binding , T-line area will not appear precipitation ribbon. If the sample does not contain drugs or their metabolites, T-line area will appear a ribbon precipitation line. The other ribbon on the strip (line C) is used to determine if the test is reliable.

Morphine colloidal gold detection test paper is a qualitative detection of morphine, opium, heroin and its metabolites in urine, food and medicine by immunoassay. It is simple, rapid and accurate. It is suitable for the detection of drug abuse.

Applies to drug addiction, hospitals, army recruiting, high-risk population survey, special industries and job screening in the screening and health and epidemic prevention departments of food inspection.
