Mango, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to mango. It helps in defining the allergen responsible for eliciting signs and symptoms, and in identifying allergens responsible for allergic response and/or anaphylactic episodes. It is also used to confirm sensitization prior to beginning immunotherapy and to investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
If not ordering electronically, complete and send an Allergen Test Request (T236) with the specimen. Centrifuge and aliquot serum into a plastic vial as collection instructions. For further details on allergens available for testing, refer to the Allergens - Immunoglobulin E (IgE) Antibodies document.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients where medical management does not depend on identifying allergen specificity. Some individuals might have measurable levels of IgE antibodies in serum that are clinically insignificant, which requires clinical context for interpretation. False positives may occur in patients with high serum IgE (>2500 kU/L) due to nonspecific binding.
