ImmunoChrome-MARIJUANA-Express strip is intended for in vitro one-stage rapid qualitative determination of marijuana and/or its metabolites in human urine by immunochromatographic analysis. The result of the determination using the ImmunoChrome-MARIJUANA-Express strip should be considered as preliminary. The use of gas chromatography/mass spectrometry (GC/MS) is recommended to confirm positive results.
Operating principle:
The determination is based on the principle of a competitive immunochromatographic assay, in which marijuana (or its metabolites) present in the analyzed sample competes with 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (the main metabolite of marijuana) immobilized on the membrane of the strip for the possibility binding with specific monoclonal antibodies to 11-nor-9-carboxy-delta-9-tetrahydrocannabinol, conjugated with colloidal gold, preventing the formation of a pink-violet line in the lower part of the test zone. The remaining reagents provide the formation of a pink-purple control line in the upper part of the test zone, regardless of the presence of marijuana, which confirms the correctness of the determination procedure. If the concentration of marijuana in the sample is above or equal to the threshold (50 ng/ml), one pink-purple line is formed in the test area, and if marijuana is absent or its concentration is below the threshold, two lines are formed.
Detection sensitivity (minimum detectable concentration) is: 50 ng/ml marijuana (or its metabolites). The analysis time is 5 minutes.
