Allergic reaction
Allergic Reaction
An allergic reaction is a hypersensitivity disorder of the Immune system. They occur when a persons immune system reacts to harmless substances. They are caused by excessive activation of two types of White blood cells; Basophils and Mast cells. These cells are activated by a type of antibody called Immunoglobulin E (IgE), which results in an inflammatory response. [1]
