Use

This test is useful for establishing a diagnosis of an allergy to spinach, defining the allergen responsible for eliciting signs and symptoms, and identifying allergens responsible for allergic response and/or anaphylactic episodes. It helps confirm 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 medical management does not depend upon identification of allergen specificity.
