Use

The test is used for establishing the diagnosis of an allergy to spruce, defining the allergen responsible for eliciting signs and symptoms, identifying allergens responsible for allergic responses or anaphylactic episodes, confirming sensitization prior to immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. It is important to note that testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients for whom medical management does not depend on allergen specificity identification.
