Home drug test principle: colloidal gold monoclonal antigens, antibody immune competition principle. When the sample contains morphine or its metabolites with the content of 300ng/ml, i.e. it integrates with the limited antibody with the small particles with the color that are fixed with the membrane, thereby preventing the test area (T-line area) antigen binding, and T-line area will not appear precipitation belt. If the specimen does not contain drugs or their metabolites, T-line area will appear a belt precipitation line. The other belt on the test strip (line C) is used to determine if the test is reliable.
The drug test applies to screening in the physical examination of the drug rehabilitation centers, hospitals, military recruiting, high-risk population survey, special industries and jobs as well as food inspections of health and epidemic prevention departments.
