Allergen Profile, Walnut, IgE With Component Reflex

This test measures specific IgE antibodies in your blood that react to different individual proteins found in walnuts. It helps identify whether a sensitivity is caused by proteins associated with severe reactions or by proteins that cross-react with pollen and typically cause milder symptoms. This distinction helps doctors differentiate between a primary food allergy and cross-reactivity from environmental triggers. However, this test cannot predict the exact severity of a future reaction or diagnose an allergy without a review of your medical history.
