This assay provides only a preliminary analytical test result. Gas Chromatography/Mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to Marijuana (THC) of abuse test result, particularly when preliminary positive results are indicated.

Marijuana is a hallucinogenic agent derived from the flowering portion of the hemp plant. The active ingredients in Cannabinoids, THC & Cannabinol can be metabolized and excreted as 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid with a half-life of 24 hours. It can be detected for 1 to 5 days after use. Smoking is the primary method of use of Cannabinoids/cannabis. Higher doses used by abusers produce central nervous system effects, altered mood and sensory perceptions, loss of coordination, impaired short-term memory, anxiety, paranoia, depression, confusion, hallucinations and increased heart rate. A tolerance to the cardiac and psychotropic effects can occur, and withdrawal syndrome produces restlessness, insomnia, anorexia and nausea.

• Test must be in room temperature (15ºC to 30ºC)
• Donor collects urine specimen in a urine cup.
• Open the sealed pouch by tearing along the notch. Remove the test from the pouch and place it on a level surface.
• Hold the sample dropper vertically, and add exactly three drops of the urine specimen into the sample well.
• The result should be read at 5 minutes. Do not interpret the result after 10 minutes. See the illustration below.

 

 

Interpretation of Results

Preliminary positive (+)

Only one colored band appears, in the control region (C). No colored band appears in the test region (T).

Negative (-)

Two colored bands appear on the membrane. One band appears in the control region (C) and another band appears in the test region (T).

Invalid

Control band fails to appear. Results from any test which has not produced a control band at the specified read time must be discarded. Please review the procedure and repeat with a new test. If the problem persists, discontinue using the

kit immediately and contact your local distributor.
