Detailed explanation-1: -A food allergy is an immunoglobulin E (IgE)-mediated hypersensitive reaction to food, which consists in the appearance of allergic symptoms; it can vary from common urticaria to even fatal anaphylaxis.

Detailed explanation-2: -Non-IgE-mediated food allergies are characterized by subacute or chronic symptoms, whereas IgE-mediated food allergies are characterized by the rapid onset of symptoms following ingestion (eg, anaphylaxis).

Detailed explanation-3: -IgE-mediated means that IgE allergy antibodies are a cause of the allergic reaction to a food. By contrast the signs and symptoms of IgE mediated food allergy usually occur within minutes of ingestion and include hives, redness of the skin, vomiting and in more severe reactions, anaphylaxis.

Detailed explanation-4: -Immunoglobulin E (IgE) – A rapid immune response that can be triggered by food. Immunoglobulin G (IgG) – A more delayed and potentially more mild immune response that can be triggered by food. Immunoglobulin A (IgA) – An antibody that can support the immune functions of mucous membranes.
