I'm taking Oxycodone HCL. I get the 15 mg tabs and cut them in half. I take 3 halves a day. Well, I came up NEG for opiates on my drug test for opiates. They did another test and I came up NEG on that one too. I dont understand how I am coming up NEG? I need the drugs for pain in my back and take them religiously. I'm confused.

It turns out the regular panel drug tests do not pick up oxycodone as an opiate. Their is a separate test for oxycodone. So, you will come up negative every time unless they specifically use the oxycodone test panel. I found this out from the lab manager at a local hospital. He's a friend.

As it turns out, My lab tech friend was correct. They did another urine sample that tests specifically for Oxycodone and I came up positive.
