Phoma betae, IgE, Serum

Clinical Use

Use

This test is useful for establishing a diagnosis of an allergy to Phoma betae, defining the allergen responsible for eliciting signs and symptoms, identifying allergens responsible for allergic response or anaphylactic episodes, confirming sensitization prior to beginning immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. It is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in cases where medical management does not depend upon 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 form (T236) with the specimen. Perform test setup interfacing between Mayo Clinic Laboratories and your Laboratory Information System using the provided setup files. Clients without access to test prices should contact Customer Service for fee information.

Limitations

Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies in serum. Results must be interpreted in the clinical context. False-positive results may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases. Testing for IgE antibodies is not useful in patients before immunotherapy, in whom the management does not depend on identification of allergen specificity.
