LC-MS/MS testing identifies oxycodone and its metabolites — primarily oxymorphone and noroxycodone — with high specificity. This information is more useful than a general opiate screen because it distinguishes oxycodone from other opioids and confirms genuine metabolism (rather than direct urine adulteration).
This test is used in pain management to verify compliance with prescribed oxycodone, evaluate suspected diversion or misuse, and provide medico-legal documentation. Sample type is urine.
