Our Urine Drug Test Kits come in 2 categories – Dip Cards and Integrated Cups, both extremely easy to use. Our one-step drug screen tests consist of a strip which absorbs the urine. The results are then seen on the window where you can read if it is positive or negative. One panel shows the results for one drug. So a Single-drug Test kit will have just one panel. Multi-drug test kits come with more than one panel, each one showing the results for a particular drug or drug category.
