Use

This test is useful for establishing the diagnosis of an allergy to vanilla. It helps define the allergen responsible for eliciting signs and symptoms and identifies allergens responsible for allergic responses and/or anaphylactic episodes. Additionally, it is used to confirm sensitization prior to beginning immunotherapy and to investigate the specificity of allergic reactions to allergen sources such as insect venom, 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 patients whose medical management does not depend on the identification of allergen specificity.
