RAST how accurate is it?
My four year old son was diagnosed with a peanut allergy at 1.5 years old, after an anaphylactic reaction. His RAST test was 7.5 for peanut and .45 for Soybean. We have managed these allergies with avoidance, however he has developed asthma and has several hive outbreaks seemingly unrelated to soy or peanut. I just had his RAST reordered and his Peanut was 74, soybean was 17.8, Wheat 1.03, Corn 1.42, sesame seed 4.45. His total IgE was 205. Our allergist who we have seen once has moved, so we are awaiting an appointment with a new group. To say that I am stunned and unsure of how to feed him is an under statement.
My question is, is the RAST accurate? How could we go from 2 allergies in 2 years to most major food groups? Between corn, soy and wheat what else is there?
I know I sound frustrated, I just don't know where to start.
Thanks for any advice.
