non-IGE mediated allergy?
I've been wondering why my son could have a negative RAST, negative skin tests, and still have an anaphylactic reaction from the food challenge.
Could it be that the RAST measures the levels of IgE, and his allergy could be non-IgE mediated? But wouldn't the protein in the skin test make him react, even if it is a non-IgE mediated allergy?
I am so confused.

other DS with pollen, animal, dust allergies
