Scallop, IgE, Serum
Use
This test is used for establishing a diagnosis of an allergy to scallop. It helps to define the allergen responsible for eliciting signs and symptoms and identify allergens responsible for allergic response or anaphylactic episode. It confirms sensitization prior to beginning immunotherapy and investigates the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. The test is not useful for determining if residual clinical sensitivity exists in patients previously treated with immunotherapy or when the medical management does not depend on identification of allergen specificity.
Special Instructions
For a listing of allergens available for testing, see the 'Allergens - Immunoglobulin E (IgE) Antibodies' document. If not ordering electronically, complete, print, and send an Allergen Test Request (T236) with the specimen.
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.
