Oxycodone showing up in urine when all I take is opana, any answers how that can be?

Perhaps something is wrong with the test? I would request (demand) testing at a laboratory, by blood test if possible. You may have to pay for the test but your name will be cleared. Check the contract you signed (if you did - most places do) and see what your rights are. You should be allowed to challenge their results with a test of your own. Doctors are all about the bottom line, so they buy the most economical tests they can which may not always be accurate. Have them test you, then go straight to the lab for your testing. Best wishes -

That has happened to me too. I have since found that opana and roxicodone do matabolize differently. I had taken a standard 5 panel test and showed negative for opiates. You have to be tested specificly for oxycodone because of how it breaks down. Hope this helps.
