Turkey Feathers, IgE, Serum

Clinical Use

Use

This test is useful for establishing a diagnosis of an allergy to turkey feathers. It helps in defining the allergen responsible for eliciting signs and symptoms and in identifying allergens responsible for allergic responses or anaphylactic episodes. This test confirms sensitization prior to beginning immunotherapy and investigates the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. However, testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients where the medical management does not depend upon the identification of allergen specificity.

Special Instructions

For a listing of allergens available for testing, refer to the Allergens - Immunoglobulin E (IgE) Antibodies document link provided on the page. If not ordering electronically, complete the Allergen Test Request form and send it with the specimen. Centrifuge and aliquot serum into a plastic vial for submission.

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 due to nonspecific binding to allergen solid phases. Testing for IgE antibodies is not useful in patients where the medical management does not depend upon identification of allergen specificity.
