Use

The test is useful for establishing a diagnosis of an allergy to rat urine protein and defining the allergen responsible for eliciting signs and symptoms. It helps identify allergens responsible for allergic response or anaphylactic episode. The test can confirm sensitization before starting immunotherapy and 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 when medical management does not depend on allergen specificity identification.
