Many patients with a history of a single tree nut allergy are told to avoid all other tree nuts. But is that necessary? If you have a tree nut allergy and were advised to avoid other tree nuts based only on a positive blood or skin prick test, you may not be allergic to the other nuts. New research strongly suggests you should consider having an oral food challenge to properly diagnose additional nut allergies, especially if you've never had a reaction to eating those tree nuts before.
