Criminal Defense Attorney
A dirty UA is evidence that you violated a condition of your parole. A single dirty UA can be handled in many different ways from calling you in for a case conference, increasing conditions, or can be the grounds for a motion to revoke parole. It will often depend on how long you have been on parole, how you been doing on parole, and other matters. It is unclear from your question if you made any admissions to the parole officer, I would recommend contacting a local attorney familiar with parole to discuss the matter.
