Use

This test is used for establishing a diagnosis of an allergy to wasp venom, defining the allergen responsible for eliciting signs and symptoms, and identifying allergens responsible for allergic response and/or anaphylactic episodes. It can confirm sensitization prior to beginning immunotherapy and investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in those whose medical management does not depend on the identification of allergen specificity.
