Marijuana Scan is a simple urine screening test for the determination of tetrahydrocannabinoid (THC) and related metabolites. The test has a high degree of sensitivity and specificity, requires no instrumentation and provides a result in a matter of minutes.

The test is extremely easy to administer with a minimum about of training and is suitable for use as a personal test or within a professional environment.

In order to use this product it is necessary to collect a urine sample in an appropriate receptacle. Drug Tests Direct recommend using a sterile urine collection cup for this purpose. You may also like to consider purchasing the Marijuana Scan Home Drug Test Kit instead, which comes packaged with the collection cup.


Marijuana Scan measures the metabolites of marijuana, listed below, at the cut-off level defined by the Australian standard AS/NZS 4380:2008, which describes procedures for the collection, detection and quantitation of drugs of abuse in urine.

Code Test Drug Cut-Off Level
THC Cannabis Metabolites 50 µg/L

Metabolites measured: 11-nor-r9-THC-9-COOH, 11-nor-r8-THC-9-carboxylic acid, 11-hydroxy-r9-THC, r8-THC and r9-THC.

Marijuana Scan undertakes analysis for the metabolites of THC using the principle of solid-phase immunoassay technology. Using this method a specific immunochemical reaction between antibodies and antigen is employed to analyse a corresponding compound within a biological matix.

The assay is based on competition between the drug conjugate and any free drug to bind with an antibody. If a metabolite of marijuana is present in the specimen undergoing analysis, it competes with corresponding conjugate for antibody-dye conjugate, which is in limited supply. If the quantity of metabolite is equal to, or greater than, the cut-off level, it inhibits binding of the conjugate to the antibody.

This is why, as illustrated below, no test line is visible when a result is positive whereas the presence of a coloured band indicates a negative result.

Lateral flow test principle


Each Marijuana Scan drug test kit contains of the following inclusions:

  • Sealed test cassette
  • Integrated Quality Control (QC)
  • Product insert

The following instructions provide details on how to use Marijuana Scan to accurately analyse a urine sample for marijuana and it’s metabolites.

  • Test with at least 50 ml of urine.
  • Remove the test card from sealed foil pouch.
  • Remove the protective cap and immerse the revealed strips into the urine sample.
  • Hold until the urine is seen to visibly migrate up each of the ten test windows. Do not allow the urine to touch the plastic section of the device.
  • Remove from the urine, replace the cap and place the test on a flat dry surface.
  • Read the results at 5–8 minutes after adding the sample.



The presence of a line next to both the Control “C” and Test “T” indicates a negative result. Please note that this does not necessarily mean there is a complete absence of drug in the specimen, only that the level is below the cut-off given in Australian standard AS/NZS 4308:2008.


The absence of a line next to the Test “T” and the appearance of a line next to the Control “C” indicates a positive test result. As with a negative result, this is an indication the concentration of tested drug(s) in the specimen is above the particular cut-off level of that component.


If there is an absence of a line in the Control “C” area following the alloted time the test should be considered invalid. In this case the sample should be re-analysed with a new test, in strict accordance with the documented procedure.

Interpretation of drug test results

Note: It is important to understand that the colour intensity of Test “T” lines can vary and that the presence of any line, no matter how faint, is still indicative of what the test suggests.
