Test Criteria

The food allergy test is conducted by an allergist. He will first ask all your symptoms and physical examination. Then he will do certain tests like

• skin prick test-In this test, a small amount of the suspected food is placed on the skin of your forearm or back. Then a small prick is made on the skin at that site. If there is redness and itching at that site it means you have food allergy.
• oral challenge test-in which small amount of food is given by mouth in form of capsule. If you develop allergic symptoms, it means you have allergy.
• elimination diet-here all suspected allergic foods are eliminated from the diet and then gradually introduced back into your diet one at a time. To find out which food causes allergic reaction.
• IgE blood test-A blood test can measure your immune system’s response to food by measuring the allergy-related antibody known as immunoglobulin E (IgE).
