Use

The test is useful for establishing a diagnosis of an allergy to rat serum protein. It assists in defining the allergen responsible for eliciting signs and symptoms. It also identifies allergens responsible for allergic responses and anaphylactic episodes, and confirms sensitization before immunotherapy. The test is part of the investigation of allergic reactions' specificity to insect venom allergens, drugs, or chemical allergens. However, testing for IgE antibodies is not beneficial for patients previously treated with immunotherapy to determine residual clinical sensitivity, or if the medical management does not depend on allergen specificity identification.
