When getting drug tested, does morphine show up differently than fentanyl?

no they are both in the same class so they will both show up the same unless the doctor wants the test sent away then they can separate the drugs in your system. Hope this helps some, marjorie zych

Yes it does. Fentanyl is a synthetic, lab created drug. Much stronger than morphine. When testing for Morphine, it will show positive for morphine metabolites.
