Use

This test is useful for establishing a diagnosis of an allergy to canary grass and defining the allergen responsible for eliciting signs and symptoms. It helps in identifying allergens responsible for allergic response and/or anaphylactic episodes, and it can confirm sensitization prior to beginning immunotherapy. It is also used to investigate 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.
