Frequently Asked Questions:
The Test Line is lighter than the Control Line. Does this mean some substance is present? No. Any test line, no matter how dark or light, is considered a negative result and should not be interpreted as a measure or the amount of substance.
How soon after use can you detect the substance in the urine and for how long can it be detected in the urine? Most panels can be detected in the urine within a few hours after use, however, this can vary depending on the type of substance taken, the amount taken, the frequency of use, and the metabolism of the person being tested. Each panel is cleared by the body at different rates. Some panels, for example THC, can stay in the body for up to several weeks after use.
When is the best time to take the test? Use first morning urine when possible as it tends to be the most concentrated urine of the day making it best for detecting any substance that may be in the system.
