This is a simple blood test that helps to diagnose allergies to certain food items. It is also called food sensitivity blood test. Food allergy is a medical condition in which your body is allergic to certain foods. Whenever you eat those foods, your body develops various grades of immune response to them. This response can vary from mild reaction to severe life-threatening anaphylactic shock.
Food allergy is usually present in children. This allergy may resolve as the child grows older but sometimes it can be present throughout life.
This test determines allergy-specific IgE in blood. The only treatment for food allergy is to avoid the allergy-causing foods.
