IgE immunoglobulins represents less than 0.1% of all antibodies, are located on mast cells and basophils, and are involved in allergic reactions.
Immunoglobulin E (IgE) is an antibody produced by the immune system.
When you have an allergy, your immune system overreacts to allergens by producing an antibody called immunoglobulin E (IgE).
These antibodies travel to cells and release chemicals that trigger an allergic reaction. This reaction usually causes symptoms in the nose, lungs, throat, or skin.
Each IgE type has a specific "radar" for each allergen type.
For this reason, some people are only allergic to cat dander (only have IgE antibodies specific to cat dander).
Others, on the other hand, have more types of her IgE antibodies and therefore have allergic reactions to multiple allergens.
