Order Walnut Allergy Test | Nut AllergiesA walnut allergy screen measures the amount of allergen-specific IgE antibody in the blood. IgE is the class of antibody the immune system produces when it identifies a substance as a threat, and it is the same antibody involved in immediate allergic reactions. This test focuses on walnut proteins specifically, so it can help clarify whether a person's symptoms are consistent with a walnut sensitization.
About Walnut Allergy Test | Nut Allergies in Calexico
Allergy testing works by looking for the immune system's response to particular allergens.
When a person is sensitized to walnut, immune cells produce IgE antibodies that recognize walnut proteins. Those antibodies bind to mast cells, and when walnut is encountered again, the cells release histamine and other mediators that cause symptoms such as hives, itching, swelling, or breathing changes.
A blood test detects the presence of walnut-specific IgE without exposing the person to the food itself. The result is reported as a numeric level, which is often grouped into categories ranging from negative to strongly positive. The size of the number does not, by itself, predict how severe a reaction will be.
Because sensitization and clinical allergy are not identical, a positive result is interpreted alongside the person's history. Some individuals have IgE to walnut yet tolerate it, while others react at low levels. A clinician uses the result together with symptom details to decide what it means for the individual.
