Prior to testing, abstain from using any THC, CBD, detox and/or diluting products. Additionally, do not drink an abnormal amount of water or any fluid. This may alter the natural state of the urine sample, resulting in an inaccurate and/or false-negative (clean) test result.

Check out our FAQ Page for more testing information.

Instructions to detect the THC metabolite in human urine:

1. Open the sealed pouch by tearing along the notch and remove the test cube and sponge collector. Stand the test cube upright on a level surface.
2. Put the sponge end of the collector in your mouth to collet oral fluid for about 7 minutes or until the sponge is fully saturated by oral fluid. NOTE: Do not chew, bite or suck the sponge.
3. Open the test cube and place the fully saturated sponge collector inside the test cube. Press the sponge collector down firmly until it reaches the bottom of the test cube, then close the cube lid tightly while compressing the collector. Keep the test cube standing upright (vertically) on a flat surface.
4. Read the results between 5-15 minutes after use.
