Use

This test measures specific IgE antibodies to hazelnuts with reflex to a hazelnut component panel if the IgE result is positive. Allergen‑specific serum IgE testing is considered comparable to skin testing and may be preferred in some clinical situations. However, a positive test result only indicates that a patient is sensitized to the allergen of concern. Many IgE‑sensitized individuals do not develop any symptoms when exposed to the allergen. A diagnosis of allergy should only be made by a trained medical provider after conducting a thorough clinical evaluation.
