Re: Are food allergy tests conclusive?
I came here just now because I'm having the exact same problem. Besides oral allergy syndrome or some kind of intolerance, there's also MSG. I was just reading that it increases histamine production by 150%, so you could be very mildly allergic to something, but if you eat it with MSG you could have a severe reaction.
But also, they can only test for about 50 foods, and there are a LOT more than 50 foods. You could very easily be allergic to something they don't have a test for.
Choose the devil you don't know.
