The tests are only about 95% correct. Yes, it's possible for people to get false positives.I'm not sure how all of this works but some medications can break down in your body and show up as another med. Fentanyl may have some of the same ingredients as Oxycodone. Did your Dr retest you? If not, I was ask him to do it. I would also tell him about these tests only being 95% accurate and ask him to research one med showing up looking like another med. I take it there was also Fentanyl in your system along with the Oxycodone?
