Use

The Lysozyme, IgE, Serum test is useful for establishing the diagnosis of an allergy to lysozyme, defining the allergen responsible for eliciting signs and symptoms, and identifying allergens responsible for allergic responses and/or anaphylactic episodes. It is also useful to confirm sensitization prior to beginning immunotherapy and 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 in whom the medical management does not depend upon identification of allergen specificity.
