Clinical Use

Use

This test is useful for establishing a diagnosis of an allergy to trees included in panel #4. It helps in identifying allergens responsible for allergic responses or anaphylactic episodes. The test can confirm sensitization before beginning immunotherapy and investigate specificity of allergic reactions to various allergens. Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or where medical management does not depend on identification of allergen specificity.

Special Instructions

This test uses a pooled allergen reagent, and a single qualitative class result and concentration is reported. It's appropriate as a first-tier test for allergic disease. Only one result is generated for each panel. In cases of a positive test, follow-up testing is required to differentiate between individual allergens in the panel.

Limitations

Individual allergen responses cannot be identified with this panel. 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. Additionally, some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies; thus, results must be interpreted in the clinical context.
