Anise, IgE, Serum
Use
The test is useful for establishing the diagnosis of an allergy to Anise and defining the allergen responsible for eliciting signs and symptoms. It helps identify allergens responsible for an 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 is not useful in patients previously treated with immunotherapy or those whose medical management does not depend upon identification of allergen specificity.
Special Instructions
If not ordering electronically, complete, print, and send an Allergen Test Request (T236) with the specimen. For a listing of allergens available for testing, see Allergens - Immunoglobulin E (IgE) Antibodies document.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies, leading to potential diagnostic confusion. False-positive results may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding. Testing for IgE antibodies is not useful in certain patient scenarios as stated, and results should be interpreted in the clinical context.
