Antigens that elicit allergic reactions are referred to as:_________
denis-greek [22]

Antigens that elicit allergic reactions are referred to as allergens.

A material or antigen that can trigger an allergic reaction is known as an allergen.

The immune system of some individuals perceives allergens as foreign or threatening. In order to protect itself from the allergen, the immune system responds by producing a particular form of antibody known as IgE.

Allergy symptoms result from this reaction.

An antigen called an allergen causes the immune system to react in an excessively ferocious way to a perceived threat that would otherwise be harmless to the body. Allergies are the term for such reactions.

Technically speaking, an allergen is an antigen that, when exposed to atopic persons, can trigger an immunoglobulin E (IgE) response, resulting in a type-I hypersensitivity reaction.

The majority of Immunoglobulin E responses in humans are only activated in response to parasite infections.
