My drug screen came back (+) for oxycodone and tramadol... I have never taken tramadol and had not taken oxy... however, like I said, I had taken vicodin the night before and provided the pharmacy drug profile to Lab Corp. The drug screen did not show vicodin... I don't know how this could happen and when I spoke to MRO they were not willing to discuss ... they simply told me that the script did not cover the drugs that showed up. Has this ever happened before?
Yes and one of the issues is that opiates (natural) undergo first pass metabolism and are converted by the liver into other compounds. The biggest issue in Australia is that we can get codeine over the counter and even a blood test recognizes it as morphine. Ibuprofen has been linked to false positives with a number of products.

I recently had oral surgery for my impacted tooth too exposed and a text to my braces. They cut out?
