Urine cassette tests are an immunochromatographic assay designed to detect human chorionic gonadotropin (hCG) in urine. Test cassettes are easy to use, simple to administer, and priced at a relatively low cost. The cassette tests work similar to a pregnancy test, and are used to detect the presence of illegal drugs in the body, most commonly marijuana. The Urine Cassette Drug Test Kit is one of the most convenient and low cost products on the market of drug screening devices.
