Oxycodone and Urine Drug Screens

Oxycodone (Percodan, Percocet, Roxicodone, Oxycontin) does not show up on most urine drug screens (but at high levels it may show up as positive opoids). To screen for diversion, I specifically order a urine oxycodone quantitative level (NOT qualitative level) for those patient who are taking oxycodone products for chronic pain.
