Anisakis, Parasite, IgE, Serum
Use
Establishing a diagnosis of an allergy to the Anisakis parasite and defining the allergen responsible for eliciting signs and symptoms. Identifies allergens responsible for allergic response and/or anaphylactic episode, confirms sensitization prior to beginning immunotherapy, and investigates the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. 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 management does not depend on identification of allergen specificity.
Special Instructions
For a listing of allergens available for testing, see the PDF provided by Mayo Clinic. If not ordering electronically, complete, print, and send the Allergen Test Request form (T236) with the specimen. Authorized users can sign in for detailed fee information. Contact your regional manager for fee schedule.
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 IgE levels (>2500 kU/L) due to nonspecific binding to allergen solid phases.
