Wasp Venom, IgE, Serum
Use
This test is used for establishing a diagnosis of an allergy to wasp venom, defining the allergen responsible for eliciting signs and symptoms, and identifying allergens responsible for allergic response and/or anaphylactic episodes. It can confirm sensitization prior to beginning immunotherapy and investigate 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 those whose medical management does not depend on the identification of allergen specificity.
Special Instructions
For tests not ordered electronically, complete, print, and send an Allergen Test Request (T236) with the specimen.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may have measurable IgE levels, which must be interpreted in the clinical context. False-positive results for IgE antibodies may occur in patients with markedly elevated serum IgE levels (>2500 kU/L) due to nonspecific binding. Testing is not recommended for monitoring previously treated patients or when management doesn't rely on allergen identification.
