What is a urine drug test?
A urine drug test is a method used to detect drugs of abuse by analyzing a person’s urine sample. The test is designed to detect a parent drug or a metabolite of a drug;
When a drug is consumed the body metabolizes it into a modified form. For example, Cocaine metabolizes into benzoylecgonine and Opiates metabolite into Morphine, this is what the device detects.
How does it work?
The first stage of a test starts with the screening process. The image ‘above’ shows a basis of what a screening device looks like. It comprises two parts; chemically coated strips and the case or card which encapsulates it. Each strip is unique and detects a specific substance. The most popular substances are Cocaine, Amphetamines, Methamphetamine, Opiates, and marijuana.
Screening devices come in two variants; a dip card or a cup. Each works the same but the process is slightly different. With the dip card, the test strips are external and dipped directly into the urine, with the cup the strips are located inside and the cup, the cup is filled with urine and the analysis starts.
