Chicken, IgE, Serum
Use
This test is used to establish a diagnosis of an allergy to chicken by identifying the specific allergens responsible for eliciting signs and symptoms. It also helps to confirm sensitization prior to beginning immunotherapy and investigate specificity of allergic reactions to allergens such as insect venom, drugs, or chemicals. In vitro serum testing for IgE antibodies indicates the immune response to allergens associated with allergic disease.
Special Instructions
Testing for IgE antibodies is not recommended for patients previously treated with immunotherapy to determine residual clinical sensitivity or when medical management does not rely on identification of allergen specificity. For ordering, complete the Allergen Test Request form (T236) if not ordering electronically.
Limitations
Results must be interpreted in clinical context as some individuals with clinically insignificant sensitivities may have measurable levels of IgE antibodies. False positives may occur in patients with markedly elevated serum IgE due to nonspecific binding to allergen solid phases. IgE testing is not useful for medical management decisions not dependent on allergen specificity.
