Use

This test is useful for establishing a diagnosis of an allergy to egg white. It helps define the allergen responsible for eliciting signs and symptoms and identifies allergens responsible for allergic responses and/or anaphylactic episodes. The test is also used to confirm sensitization prior to beginning immunotherapy and to investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. However, it is not useful in patients previously treated with immunotherapy or in those whose medical management does not depend upon the identification of allergen specificity.
