PROFESSIONAL DRUG TEST DrugTest Marijuana Please read all the information in this package insert before performing the test. The Drug Test Marijuana Rapid Test Cassette (Urine) is a rapid urine screening test that can be performed without the use of expensive instruments. The test utilizes a monoclonal antibody to selectively detect elevated levels of marijuana in urine. The THC Rapid Test Cassette yields a positive result when the concentration of marijuana in urine exceeds 50ng/ml. This assay provides a preliminary analytical test result. A more specific alternate chemical method must be used to obtain a confirmed analytical result. Gas chromatography/mass spectrophotometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used. THC (Δ9-tetrahydrocannabinol) is the primary active ingredient in cannabinoids (marijuana). When smoked or orally administered, it produces euphoric effects. Users have impaired short term memory and slowed learning. Users may also experience transient episodes of confusion and anxiety. Long term relatively heavy use may be associated with behavioural disorders. The peak effect of smoking marijuana occurs in 20-30 minutes and the duration is 90-120 minutes after one cigarette. Elevated levels of urinary metabolites are found within hours of exposure and remain detectable for 3-10 days after smoking. The main metabolite excreted in the urine is 11-nor-Δ9-tetrahydrocannabinol-9- carboxylic acid (Δ9-THC-COOH). PRECAUTIONS • Do not use after the expiration date. • The test should remain in the sealed pouch until use. SPECIMEN COLLECTION AND PREPARATION • The urine must be collected in a clean and dry container. • Urine collected at any time of the day may be used. • Urine specimens exhibiting visible particles should be filtered, or allowed to settle to obtain clear specimen for testing. DIRECTIONS 1. Collect urine in a clean and dry container. 2. Bring the pouch to room temperature before opening it. 3. Remove the test from the pouch and use it within one hour. 4. Place the test cassette on a clean and level surface. 5. Hold the dropper vertically and transfer 3 full drops of urine to the specimen well of the test cassette, and then start the timer. 6. Avoid trapping air bubbles in the specimen well (see illustration below). 7. Wait for the colour line(s) to appear. 8. The result should be read at 5 minutes. 9. Do not interpret the result after 10 minutes. 3 Drops of Urine THC C T S C T THC S Positive Negative Invalid READING THE RESULTS QUESTIONS & ANSWERS POSITIVE Q: How does the result window appear if the results are positive?
