Approximate cut-off concentrations (ng/mL) ----------------------------------------- Buprenorphine No cross-reactivity Codeine 224 6-Acetylmorphine (heroin metabolite) 386 Fentanyl No cross-reactivity Heroin 366 Hydrocodone 1,086 Hydromorphone 1,425 Meperidine > 100,000 Methadone No cross-reactivity Morphine 300 Oxycodone* > 75,000 *Therapeutic use of oxycodone in the absence of any other opiates is unlikely to result in a positive opiates screen.
