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.
