I posted earlier about a new test that can determine to which peanut proteins you're sensitized, but so far I've gotten no responses. Has anyone heard of this test from Phadia or taken it? Some people diagnosed with pnt allergy are actually more sensitized to a peanut protein (Ara h8) that is similar to birch pollen, and don't have true peanut allergy, according to this article: http://www.medicalnewstoday.com/articles/185263.php

If I understand correctly, only those with a high reactivity to the protein Ara h2 are the ones with true peanut allergy. This is based on reasearch published this year in the Journal of Allergy and Clinical Immunology.

This test might make sense for those of us whose children were diagnosed with pnt allegry, but who have never had a clinical reaction.

I've never heard of this, but I will be asking my allergist about it next time I take my daughter in.

I should mention that this test has not been FDA approved yet. It's just being marketed to allergists so far. And it's my understanding that it can give you an idea of whether you're at high or low risk of anaphylaxis.

I haven't heard of this test before. My daughter has a severe peanut allergy, but does not have reactions and hasn't had any kind of reaction in about 7 years. We are very very careful which is why she doesn't have reactions, at least that's what I thought. She does have other allergies - a lot - all of them non food. I wonder if Birch Pollen is one of them.

I've been doing some more research on birch pollen allergy. It really is very interesting. Does anyone know anymore about this? Birch pollen or peanut allergy. Could it really be a birch pollen allergy? My daughter tested 2+ for red birch, but a 6 for the tree pollen mix.
