Can you tell me about allergies to wheat, corn, peanuts, soy, walnuts, shrimp, clam, and scallops?

Food allergy. When it comes to food allergies, especially in patient with multiple food allergies like yourself, the diagnosis of it should be taken very careful so we don't over-diagnose it. Over-diagnosis will bring unnecessary burden to your quality of life. Diagnosing should be correlate with clinical symptoms of wheezing, hives, abdo pain... Lab tests help us gauge the risk of having food allergy only.
