Banana, IgE, Serum
Use
This test aids in establishing a diagnosis of an allergy to bananas and in defining the allergen responsible for eliciting signs and symptoms. It identifies the allergens responsible for allergic response and/or anaphylactic episodes and confirms sensitization prior to beginning immunotherapy. It also investigates 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 where medical management does not depend on identifying allergen specificity.
Special Instructions
If not ordering electronically, complete, print, and send an Allergen Test Request (T236) with the specimen. For any allergen listing, see Allergens - Immunoglobulin E (IgE) Antibodies documentation.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies in serum, and test results must be interpreted in the clinical context. False-positive results for IgE antibodies may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases.
