Drug test

A drug test is an analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva to find a specific or any kind of drug in a person's system. These drugs can be done for employment reasons or during sports to see if any athletes are using illegal steroids.^[1]
