Chick Pea, IgE, Serum
Use
The test is useful for establishing a diagnosis of an allergy to chick pea and defining the allergen responsible for eliciting signs and symptoms. It's also utilized for identifying allergens responsible for allergic response and/or anaphylactic episodes, confirming sensitization prior to beginning immunotherapy, and investigating the specificity of allergic reactions to various allergens.
Special Instructions
For a listing of allergens available for testing, see the detailed Allergens - Immunoglobulin E (IgE) Antibodies document. If not ordering electronically, complete, print, and send an Allergen Test Request form (T236) with the specimen.
Limitations
Testing for IgE antibodies is not useful in patients who have undergone immunotherapy to determine if residual clinical sensitivity exists, nor in patients for whom medical management does not depend on identification of allergen specificity. 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.
