Use

This test is useful for establishing a diagnosis of an allergy to horsefly or stablefly and for defining the allergen responsible for eliciting signs and symptoms. It helps identify allergens that are responsible for allergic responses and/or anaphylactic episodes. The test can confirm sensitization prior to starting immunotherapy and can also be used to investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. The in vitro serum testing for IgE antibodies provides an indication of the immune response to allergens that may be associated with allergic disease.
