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

Limitations
