DUI Arrest Rights Violated?

I was arrested for a DUI last night. I'm only 18 so i'm not legally allowed to have any alcohol in my system and i only had about 5 beers in my system. I passed all of the field sobriety tests but i did not pass the breathalyzer or blood test. I asked them what number I blew multiple times but i was never told. So my question is are they required to tell me what my BAC is? because no one told me the entire night and I still don't know. Also are they required to read you your Miranda (spelling?) Rights when they put you in the squad car and take you to jail? Thanks anything will help
