Use

This test is useful for establishing a diagnosis of an allergy to turkey feathers. It helps in defining the allergen responsible for eliciting signs and symptoms and in identifying allergens responsible for allergic responses or anaphylactic episodes. This test confirms sensitization prior to beginning immunotherapy and investigates the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. However, testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients where the medical management does not depend upon the identification of allergen specificity.
