Food allergy test came back negative, but doc says it doesn't test for allergy to genetically modified forms of same foods? how do i test gmo allergy?

Food allergy: I don't think you will find a test for genetically modified food but depending on your symptoms you can undergo a double blind placebo controlled food challenge to determine if indeed you are allergic to a certain food. Ask your board certified allerkgist.

No such test: I have colleagues here who will disagree, but I think that If the dangers were real, by now the NIH research piranhas wouldn't allow GMO's in their cafeteria -- and anyone who could demonstrate a real effect would make his/her reputation. Scaremongers encourage you to self-diagnose, and if you do this, you will never feel well again. Look elsewhere to explain your symptoms and be discerning.
