Aureobasidium pullulans, IgE, Serum
Use
This test is used for establishing a diagnosis of an allergy to Aureobasidium pullulans and defining the allergen responsible for eliciting signs and symptoms. It also helps in identifying allergens responsible for allergic response and/or anaphylactic episode, 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 is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients where the medical management does not depend upon identification of allergen specificity.
Special Instructions
For a listing of allergens available for testing, refer to the provided PDF. Complete, print, and send an Allergen Test Request form (T236) with the specimen if not ordering electronically.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies in serum. 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.
