How can i test for food allergies?

See an allergies: Food allergies allergies are easily confused with intolerance and other reactions. I recommend seeing a board certified allergist. They will do a thorough history and physical and if indicated test for food allergies.

Simple/less simple: Many PCP's can review your symptoms and order a set of blood tests through a variety of labs that correlate well with formal skin testing. With these results in hand you could confirm or exclude some of the foods you are confirmed about. If this did not help in the long run,a secondary evaluation by an allergist may provide better information.
