About Walnut Allergy Test | Nut Allergies in Berkeley
Walnut allergy testing is a focused blood test that looks for specific IgE antibodies directed at walnut proteins.
The test requires a blood sample, which is analyzed for IgE antibodies that bind to walnut allergens. Antibodies are part of the immune system, and in allergic individuals, IgE can recognize otherwise harmless proteins from foods such as walnuts.
Results are reported as a quantitative or semi-quantitative value, often alongside a reference range. Higher values generally indicate a greater likelihood of sensitization, but the result must be interpreted with the person's symptoms, exposure history, and other clinical findings.
Walnuts are tree nuts, and reactions to one tree nut do not automatically mean reactions to all others. A clinician can use this result, together with other tests and history, to guide diagnosis and management.
