Allergic Conditions: Allergen

An allergen is the source of an allergy-producing substance, the allergy-producing substance itself, or one or more of the specific proteins that makeup the substance and provoke the immune response, including IgE antibodies. Allergens are often common, usually harmless substances such as pollen, mold spores, animal dander, dust, foods, insect venoms and drugs.

Resources about allergens:

Visit an allergist/immunologist to learn more about allergic disease and your own medical condition. To find an allergist/immunologist near you, use the AAAAI's online Physician Referral Directory.
