Order Walnut Allergy Test | Nut AllergiesA walnut allergy test measures the immune system's response to walnut proteins. It is used when a reaction to walnuts or other tree nuts is suspected, or when a clinician wants to confirm or rule out sensitization. The test relies on a blood sample and reports the level of specific IgE antibodies directed against walnut.
About Walnut Allergy Test | Nut Allergies in Seattle
Specific IgE testing is a laboratory method for identifying antibody responses to particular allergens. In the case of walnut, the assay looks for immunoglobulin E that binds to walnut proteins.
IgE is an antibody class associated with immediate-type allergic reactions. When a person is sensitized to walnut, their immune system may produce IgE that recognizes proteins in the nut. A blood test detects this antibody in the circulation rather than applying an extract to the skin.
Results are reported as a quantitative value, often in kilounits of antibody per liter. A detectable level indicates sensitization, but sensitization alone does not always mean a clinical allergy will occur on exposure. The test is interpreted alongside the patient's history, symptoms, and other findings.
Walnut is a tree nut, and reactions to one tree nut can sometimes accompany reactions to others. A clinician may order additional tests for related nuts such as pecan, hazelnut, or almond when the history suggests broader tree nut sensitivity. The walnut test itself is specific to walnut proteins.
