My Daughter Is 16 And Has Severe Food Allergies To

My daughter is 16 and has severe food allergies to tree nuts, peanuts, and shellfish. She also has several oral syndrome allergies. She has had 7 anaphylactic shock events in the past three months. Her overall IgE results just came in and she is over 400. Her doctor just said that she is having Idiosyncratic anaphalatic events. Not sure exactly what that means. She seems to react to minute trace amounts of protein that she is allergic to.I am wondering if you feel she is a good candidate for Xolair injections once a month and/or desensititization to help her to live a normal life.
