Pumpkin Seed, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to pumpkin seed and defining the specific allergen responsible for eliciting signs and symptoms. It helps identify allergens responsible for allergic responses and/or anaphylactic episodes, confirms sensitization prior to beginning immunotherapy, and investigates 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
To order this test, complete the Allergen Test Request (T236) form if not ordering electronically. Refer to the Allergens - Immunoglobulin E (IgE) Antibodies PDF for a comprehensive list of allergens available for testing.
Limitations
The test must be interpreted within the clinical context. Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies in serum, which could lead to false-positive results. Additionally, false positives may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases.
