MarijuanaScan is an easy, visually-read screening test with a high degree of sensitivity and specificity, that does not require instrumentation.
MarijuanaScan tests are based on the principle of specific immunochemical reaction between antibodies and antigens to analyze particular compounds in human urine specimen. The assay relies on the competition for binding antibody between drug conjugate and free drug which may be present in the urine specimen being tested.
MarijuanScan is a rapid, one step immunochromatographic assay for the qualitative determination of THC (Tetrahydrocannabinoid) and its metabolites in human urine. The test is used to screen the presence of 11-nor-Δ9-THC-9-COOH in human urine for a cutoff of 50 ng/ml.
Summary and Explanation
The agents of Marijuana that cause various biological effects in humans are called cannabinoids. Cannabinoids are a central nervous stimulant that alters mood and sensory perceptions, produces loss of coordination, impairs short-term memory and produces symptoms of anxiety, paranoia, depression, confusion, hallucination and increased heart rate.
Expected ResultsMarijuanaScan is a qualitative assay. It identifi es 11-nor-Δ9-THC-9-COOH in human urine at a concentration of 50 ng/ml or higher. The concentration of the 11-nor-Δ9-THC-9-COOH can not be determined by this assay.
The test is intended to distinguish negative results from presumptive positive results. All positive results must be confirmed using an alternate method, preferably GC/MS.
SensitivityThe following table lists compounds that are detected by MarijuanaScan Tests:
Interference testingThe following substances did not interfere with the MarijuanaScan test:
SpecificityThe following compounds show no cross-reactivity at concentrations up to 100 µg/ml unless specified:

Interpretation of Results
• Negative:The appearance of a Control line (C) in the test window and a line in the Test Zone (T) indicates a negative result. The color intensities of the Control line and Test Zone line may not be the same. A negative result does not indicate the complete absence of THC in the specimen, it only indicates that the levels of THC are below the Australian Standards cut-off level of 50ng/ml.
• Positive:The appearance of only a Control line (C) in the test window and no line next to the Test Zone (T) indicates that the result is positive. This is an indication that the THC in the specimen is at or above the Australian Standards cut-off level of 50ng/ml.
• Invalid:A distinct Control line (C) should always appear. If there is no line formation in the Control line (C) position, the test result is invalid. Retest the sample with a new device.
• Note: Any colour line in the test area, no matter how faint, indicates a negative result. There is no meaning attributed to line colour intensity or width. The result must be interpreted at 5-8 minutes. Do not interpret the results after this time. To avoid confusion, discard the test device after reading the result.
Storage and StabilityThe test device should be stored at 2° to 30° C and will be effective until the expiration date.
Quality Control1. The control band is an internal reagent and procedural control. It will appear if the test has been performed correctly and the reagents are reactive. 2. Control standards can be used to validate reagent performance and establish test reliability. Controls which are not provided with this test are commercially available.
