I went to the doctor to see if i am allergic to almonds , he mentioned the 3 most common tree nut allergies & i can't remember what he said.

Tree nuts: Tree nuts include, but are not limited to, walnut, almond, hazelnut, cashew, pistachio and brazil nuts.

Not by test alone: The diagnosis of allergy must be made by the history and not by test result alone. Although people allergic to one nut is more at risk to be allergic to another one, this is more likely due to the person's propensity to become allergic and not due to cross-reactivity between the nuts. If you don't have problem after eating a nut, you are not allergic to it no matter what the test shows.
