# Allergen Profile, Nut, IgE With Component Reflexes

> This test measures specific antibodies in your blood to see if your immune system reacts to various nuts, such as peanuts, cashews, or walnuts. It helps determine if symptoms like hives or swelling are caused by a nut allergy and uses component testing to pinpoint which specific proteins are triggering the response. This detailed breakdown helps distinguish between a risk for severe reactions and milder sensitivities often caused by cross-reactions with pollen. While these results provide important clues, the test alone cannot diagnose an allergy or predict exactly how severe a future reaction might be.
