The Utest THC 15ng/mL is the most sensitive drug test for THC and is also the lowest detectable amount of THC in the urine. If you can pass a 15ng/mL THC test, you can be confident you are clean.
- Bring the pouch to room temperature (between 15-30 degrees).
- Remove the test from the foil pouch.
- Remove the cap from the test stick and insert the absorbent end into the urine sample.
- Leave the test stick in the urine sample until the control line C appears.
- Replace the cap back onto the test stick and lay it on a flat surface for 5 minutes.
- Read the results at 5 minutes, and disregard any reading after 10 minutes.
NEGATIVE RESULT (SUCCESS!): Two lines will appear, one next to the C and one next to the T.
POSITIVE : One line appears next to the C and no line appears next to the T.
The shade on the T line may vary, but even a faint line on the T indicates a negative result.
