I'm kinda freaking out today. Just got home from allergist who refused to do any further testing to confirm PA dx. Only testing he has had was a RAST test which came back at 7.0. Our family is relocating to Shanghai next month and I want to know FOR SURE before we go over there. Does anyone have any resources for living in Shanghai with PA? Thanks so much!

Was there a reaction that prompted testing? RASTs have a significant enough false positive rate that you wouldn't want to rely on it alone to diagnose an allergy but if there was a known reaction a RAST is often used to confirm it.
