Use

This test is useful for establishing the diagnosis of an allergy to date, tree by defining the allergen responsible for eliciting signs and symptoms. It helps identify the allergens responsible for allergic responses or anaphylactic episodes, confirm sensitization prior to immunotherapy, and investigate allergic reactions to different allergens like drugs or chemical allergens. IgE antibodies indicate the immune response and its role in allergic diseases, thus helping differentiate allergic disorders from other conditions.
