Get results in minutes in the comfort of your own home with these true-level instant drug test multi-drug test dip cards. They will help you to determine whether an illegal substance is present in a person's system. The pack includes 10 tests with easy-to-follow instructions. Each one is individually wrapped to retain its quality. With accurate results in as little as five minutes, the home urine drug test kit dip card is ideal for home, school, or work. It is quick and simple to use. Just dip the test in the urine and read the results. A negative result will show a visible line in each control region and the appropriate test region. This indicates that the concentration of the corresponding drug in that specific zone is zero or below the detection limit. If positive, a band will not appear in the test region. If one or both of the control boxes remain blank, the test is invalid. Most drugs can be detected in the urine within a few hours after taking the drug. However, this can vary depending on the type taken, the amount taken, the frequency of use, and the metabolism of the person being tested.
