# Hazelnut (Filbert)

> This test measures the amount of IgE antibodies in your blood that react specifically to hazelnuts. It helps show whether your immune system identifies this nut as a threat, which is useful for investigating symptoms like hives, swelling, or digestive issues after eating. This analysis helps determine if hazelnuts are a likely cause of your symptoms compared to other potential triggers. However, a positive result indicates sensitization and cannot alone confirm a food allergy or predict the severity of a future reaction.
