Wormwood, IgE, Serum
Use
The Wormwood, IgE test is used to establish a diagnosis of an allergy to wormwood, define the allergen responsible for eliciting allergic signs and symptoms, and confirm sensitization prior to immunotherapy. It helps in identifying allergens responsible for allergic responses and anaphylactic episodes, and in investigating the specificity of allergic reactions to allergens such as insect venom, drugs, or chemicals. Testing for IgE antibodies can confirm sensitization prior to the commencement of immunotherapy.
Special Instructions
If not ordering electronically, complete, print, and send an Allergen Test Request (T236) with the specimen. Specify the allergens needed for testing to ensure correct processing.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in situations where medical management does not rely on identifying allergen specificity. False-positive results may occur in patients with significantly elevated serum IgE due to nonspecific binding. Test results should be interpreted in the context of clinical information.
