Welcome! So my goal here is not to go against the medical advice you have been given, but as someone who was given incorrect advice many years ago having to do with sesame...it's just something to think about or get a second opinion. The quick backstory is my son at 4 had a reaction to a tree nut and was then tested for peanuts, tree nuts and sesame. Tree nuts came up positive as did sesame, however, my son had been eating Kashi cereals (which contain sesame) with no issues. The allergist told us to take it out of his diet, we did. We later found out years later from another allergist that unless there is a history of reactions, then we should not have taken the food out of his diet. He is turning 12 soon and just passed a sesame challenge. Maybe he was allergic, maybe he wasn't, but we spent 7 years avoiding sesame and maybe we didn't need to.
What kind of testing did the allergist do? Spt or rast?
