Use

This test is useful for establishing a diagnosis of an allergy to mountain cedar and defining the allergen responsible for eliciting signs and symptoms. It helps in identifying allergens responsible for allergic response and/or anaphylactic episodes, and can be used to confirm sensitization prior to beginning immunotherapy or to investigate the specificity of allergic reactions to various allergens such as insect venom, drugs, or chemicals. Testing for IgE antibodies is not useful in patients previously treated with immunotherapy or where identification of allergen specificity is not critical for medical management.
