Kiwi Fruit, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to kiwi fruit by identifying the allergen responsible for eliciting signs and symptoms. It assists in 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 in whom the medical management does not depend upon identification of allergen specificity.
Special Instructions
Not provided.
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 serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases.
