I have recently had a drug screen test. I told the doctor before taking the test that I was using medication due to sinus problems. Did the medication that I took do something to the urine to make it come out positive. Thank you for your help, God bless. Possibly, it depends on the test and the amount of medication you were taking.
Screening tests are cheap but, have error.
More specific tests cost more money. This is astonishing because I have never even seen the drug. Some dentists could use cocaine to stop bleeding also the xylocaine could be picked up depending on the sensitivity of the test. On my first day they sent me for a physical and a drug test. Four days later, I was being walked out of the building for testing positive for cocaine.
