Feather Panel # 2, Serum
Use
The test is primarily used for establishing a diagnosis of an allergy to chicken, duck, goose, and turkey. It helps in defining the allergen responsible for eliciting signs and symptoms, identifying allergens responsible for allergic responses and/or anaphylactic episodes, confirming sensitization prior to beginning immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
This test uses a pooled allergen reagent and provides a single qualitative class result and concentration. It is considered an appropriate first-tier test for allergic disease. Follow-up testing is required to differentiate between individual allergens in the panel if a positive test result is obtained.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine the existence of residual clinical sensitivity. It is also not beneficial in cases where medical management does not depend on identifying allergen specificity. False-positive results may occur in patients with significantly elevated serum IgE levels (>2500 kU/L) due to nonspecific binding to allergen solid phases.
