Drug test strips work by detecting the presence of specific drugs or drug metabolites in urine. The strips contain specific antibodies or enzymes that react with the drug or drug metabolites, producing a visible color change on the strip. The intensity of the color change is proportional to the amount of drug or metabolite present in the urine sample. Different drug test strips are designed to detect different drugs or classes of drugs, such as opioids, amphetamines, cocaine, marijuana, and benzodiazepines. The accuracy of drug test strips can vary depending on the type of drug being tested, the quality of the strip, and the conditions of the testing. It is important to follow the manufacturer’s instructions carefully to ensure accurate results.
