A study was recently conducted to determine if those patients who test positive for peanut allergy through a blood or skin test could really tolerate peanut. Of the 933 children who tested positive for peanut allergy, the majority didn't have a peanut allergy when orally challenged. Isn't that something????
Now, this is not something to be tried at home; however, it may be something worth discussing with your allergist. I know that my peanut allergic child has never had peanuts, nor has he been orally challenged to peanuts. We're just going with the allergy on the basis of blood and skin test results.
In the same study in The Journal of Allergy and Immunology also used component-resolved diagnostics (a more sophisticated blood test) to determine if they could find differences between the children with peanut allergy and those who could tolerate peanut. Researchers determined that component-resolved diagnostics may indeed help in determining whether or not a person truly is peanut allergic.
I'm finding this all very interesting. I don't want to put my child through inaccurate tests. I really want to know if a food is dangerous for him or not!
