Can touching a Fentanyl patch make it show up in urine test?

Fentanyl, like Oxycodone, does not show up on most standard urine screens for opiates due to its chemical makeup, which differ from natural opiates. However, it is detectable in urine and blood, with specialized testing using gas chromatography. Much of the information that has been released concerning Fentanyl and Oxycodone urine testing is inaccurate - read the link below to the Mayo Clinic report which clarifies errors in the record.


How long before Fentanyl can no longer be detected in basic blood work or a urine test?

In a study of 7 patients given fentanyl in surgery - Fentanyl and its two metabolites (norfentanyl and despropionylfentanyl) were extracted from samples and analyzed by gas chromatography/mass spectrometry. Unchanged fentanyl was detectable in urine in all patients immediately postoperatively and in 3 of 7 patients at 24 hours. By 72 hours, fentanyl was undetectable. Norfentanyl was present in larger quantities than fentanyl immediately postoperatively and was detected in all patients at 48 hours and in 4 of 7 patients at 96 hours.

It depends on the test used and how recently you consumed the fentanyl. I would assume it will be detected. Don't "eat" fentanyl. It's neither safe nor real bright.
