Reporting Name
Raspberry, IgEUseful For
Establishing the diagnosis of an allergy to raspberry
Defining the allergen responsible for eliciting signs and symptoms
Identifying allergens:
- Responsible for allergic disease and/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
Testing for IgE antibodies is not useful in 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.
