ALLERGY



It is a hypersensitivity to a particular substance which, if inhaled, ingested or touched for some characteristic symptoms. The substance to which they are allergic is called a "allergen", and the symptoms are defined as "allergic reactions". When an allergen enters the body of a subject allergic, the immune system responds to this by producing a large amount of antibody called IgE. (ALERGIA)
