Walnut (f256) IgE details
What Walnut (f256) IgE shows
This test measures IgE antibodies specific to walnut nut proteins to check whether your immune system is sensitized to this tree nut, which is eaten on its own and in baked goods, salads and sauces. It can help look into reactions such as mouth itching, hives, swelling, vomiting or breathing trouble after eating walnut. Tree nut allergies can cause serious reactions, and walnut often cross-reacts with pecan. A positive result shows sensitization, not necessarily a clinical allergy, and some sensitization comes from cross-reacting pollen proteins. Results are interpreted against your symptoms and history, sometimes with component testing. This is separate from walnut tree pollen testing.
Tests that include Walnut (f256) IgE
This test checks for walnut allergies by measuring the IgE antibodies in your blood. A higher level of these antibodies can indicate an allergic reaction to walnuts, helping to diagnose and manage potential food allergies.
- Walnut (f256) IgE Measures IgE antibodies to walnut to check for allergic sensitization to this tree nut, interpreted alongside any symptoms after eating it.
This panel tests for specific IgE antibodies to 17 foods (with an emphasis on tree nuts) that are commonly associated with allergies. 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.
- Almond (f20) IgE Measures IgE antibodies to almond, a tree nut, used to check for allergic sensitization that may explain your symptoms.
- Brazil Nut (f18) IgE Measures IgE antibodies to Brazil nut, a tree nut, to check for allergic sensitization that may explain reactions after eating it.
