The process for identifying if a substance remains in a person’s body is a very precise chemical experiment. In the case of marijuana, the active ingredient, THC, is metabolized primarily into 11-Nor-9- carboxy-THC, which remains detectable in urine for several days up to weeks after consumption. The reagent in this test reacts with that specific compound and, if the threshold isn’t met, the unreacted test reagent turns pink, indicating a negative result. Regardless of your opinion on the use of marijuana, the chemical idenitification process is a clever scientific test.
1. Collect a urine sample using a suitable clean container.
2. Open the foil pouch at the notch and remove the test device.
3. Use the dropper to add 4 drops of urine into the sample well “S” waiting 5 seconds between drops.
4. Observe migration. Positive results may be observed as soon as 5 minutes, depending on the concentration of the THC in the tested specimen. To confirm negative results, a complete reaction time of 8-10 minutes is required. Do not interpret results after 15 minutes.
