Does oxycodone use explain a morphine (+) result?

Can a prescription for oxycodone adequately explain a confirmed positive for opiates-morphine? (Level of 4241 ng/mL, if that matters.) The certifying scientist confirmed my impression that it does not, but I told the donor that I would triple-check. It's a non-regulated test. Thank you.

Oxycodone is not metabolized to morphine and therefore is not the source of the morphine result.

See the metabolism chart for opiates posted for an earlier inquiry - a most handy MRO reference.
