Use

The test is useful for establishing a diagnosis of an allergy to latex and defining the allergen responsible for eliciting signs and symptoms. It helps in identifying allergens responsible for allergic responses and/or anaphylactic episodes, confirming sensitization prior to beginning immunotherapy, and investigating 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 individuals where the medical management does not depend on the identification of allergen specificity.
