Hornbeam, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to hornbeam. It helps define the allergen responsible for eliciting signs and symptoms and identifies allergens responsible for allergic responses or anaphylactic episodes. It can also confirm sensitization prior to beginning immunotherapy or investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
If not ordering electronically, complete, print, and send an Allergen Test Request (T236) with the specimen.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in cases where medical management does not rely on allergen specificity.
