The principle of immune competition between colloidal gold monoclonal antigens and antibodies. When the content of morphine or its metabolites in the specimen reaches 300ng/ml, it binds to a limited antibody with chromogenic small particles fixed on the osmotic membrane, thereby preventing it from binding to the antigen in the test area (T-line area), and no precipitation bands will appear in the T-line area. If the specimen does not contain drugs or their metabolites, a chromosomal precipitate line will appear in the T-line area. Another color strip (C-line area) on the test paper is used to determine the reliability of the experiment.
