Reporting Name
Nuts Allergen ProfileUseful For
Establishing a diagnosis of an allergy to nuts
Defining the allergen responsible for eliciting signs and symptoms
Identifying allergens:
-Responsible for allergic response or anaphylactic episode
-To confirm sensitization prior to beginning immunotherapy
-To investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens
This test is not useful for patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients in whom the medical management does not depend upon identification of allergen specificity.
