Allergen, Individual – Food Hazelnut (Corylus avellana) Test, also known as the Hazelnut Allergy Test or Nut Allergy Test, is a blood test that helps determine if you are allergic to hazelnuts. Hazelnuts are a type of tree nut that are a common cause of food allergies. This test specifically measures the level of Immunoglobulin E (IgE) antibodies in your blood that react to hazelnut allergens. These antibodies trigger an immune response in people with nut allergies, potentially leading to various allergic reactions, ranging from mild symptoms like itching and hives to severe, life-threatening anaphylaxis.

What is the Allergen, Individual – Food Hazelnut Test?

This test involves a simple blood draw from a vein in your arm. The blood sample is then analyzed in a laboratory to measure the levels of IgE antibodies specific to hazelnut allergens.
