LC-MS/MS testing identifies specific opiates and their metabolites in oral fluid — including morphine, codeine, hydrocodone, hydromorphone, oxycodone, and oxymorphone — with high specificity. Oral fluid samples reflect recent use, typically within 24-48 hours.
This test is used in workplace drug testing, addiction treatment programs, and clinical situations where recent opiate use is of interest. Observed sample collection eliminates concerns about tampering. Sample type is oral fluid.
