I posted elsewhere before. Was I not tested for oxycodone? They said I didn't test positive for it

A drug test looks for signs of one or more illegal or prescription drugs in a sample of your urine, blood, saliva, hair, or sweat. The purpose of a drug test is to look for drug use and misuse, which includes: using any illegal drugs or misusing prescription medicines, which means taking prescription medicines in a different way or for a different purpose than your provider prescribed.
