Why would Oxycodone show on a urine test when all I take is Hydrocodone?

false positive-this initial screening is unreliable. That's why they do one in a real one in a lab. One grandson lost a job because of that. He was on probation, so the PO put him in jai,l and he lost his job. They released him 2 weeks later with a compensation check and a letter clearing him of any drug use, but his job was gone. The actual lab work that's being done will clear you.

That's strange. Same happened to my husband. He took a urine test for his doctor, and it came up as hydromorphine. We've never even heard of such a thing. He had only had hydrocodone the week before. His doctor stopped seeing him and referred him to drug counseling. We looked it up online and sometimes your system can mix drugs and break them down into other substances. Although he didn't take that particular drug, his body fooled the test. Hopefully the lab will confirm you're clear.

that happened to me, my doctor said on the generic drugs, sometimes other things will show up cause they get cross contamination. i think it's because they dont clean up real well after making a batch of medication. i take oxycodone, but hydrocodone showed up in my urine test. he said as long as it was a very small amount, that's probably what happened.
