(al′ĕr-jĕn)

[aller(gy) + -gen]
Any substance that causes a hypersensitivity reaction or abnormal immune response. Allergens do not stimulate an immune response in everyone, only in those sensitized to them. Common allergens include inhalants (dusts, pollen), foods (wheat, eggs), drugs (aspirin, serum), infectious agents (e.g., bacteria, viruses), contactants (chemicals, animals), and physical agents (heat, cold).SEE: allergy; SEE: antigen; SEE: irritation; SEE: sensitization; SEE TABLE: Common Allergies and Allergens
