Its my understanding that Suboxone stays is in your system for at least 72 hours and has trace metabolites that can be detected in urine for up to 10 days (depending on strength and how long one has been on it).
Suboxone: It can be detected in UDS up to 5-7 days. Assuming you are taking a Rx of Suboxone, it should be detected in the Urine and a Dr. will be looking for it to be positive, etc.
