Epicoccum purpurascens, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to Epicoccum purpurascens, defining the allergen responsible for eliciting signs and symptoms, identifying allergens responsible for allergic response 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. Testing for IgE antibodies provides an indication of the immune response to allergens associated with allergic disease.
Special Instructions
For a listing of allergens available for testing, see Allergens - Immunoglobulin E (IgE) Antibodies PDF. If not ordering electronically, complete, print, and send an Allergen Test Request (T236) with the specimen.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in patients whose medical management does not depend upon identification of allergen specificity. Some individuals with clinically insignificant sensitivity may have measurable levels of IgE antibodies, which must be interpreted in 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.
