Is it possible to have DUI charges reduced because of breathalyzer results not shown and Miranda rights were never read in Pennsylvania?

I was stopped by a police officer Friday night. He asked me to get out of my car, administered a breathalyzer and a standard DUI test. He placed me under arrest. Then I was escorted to a hospital, given a blood test, and processed at the courthouse afterwards. I was told they would follow up in a few weeks. I never admitted to DUI.
