IgE (Immunoglobulin E) Blood Test

Antibodies, also known as immunoglobulins, are crucial components of the immune system that aid in the body's defence against pathogenic bacteria and viruses. Antibodies are divided into five main groups and several subclasses.

When someone has an allergy, their immune system responds excessively by generating IgE to a harmless allergen (such as food, grass, or animal dander). Usually, this reaction irritates the nose, lungs, throat, and skin.

To determine whether a person is allergic to a particular allergen, the allergen-specific IgE antibody test is employed. The amount of IgE antibody that is targeted for a potential allergen in the blood is measured.
