Hazelnut Allergy Test

This test measures hazelnut-specific IgE antibodies as a percentage of total IgE in blood, providing both sensitization detection and relative severity assessment. Hazelnut is a tree nut allergen that can trigger allergic reactions ranging from oral allergy syndrome to anaphylaxis. The percentage indicates what proportion of your immune response is directed at hazelnut allergen. Higher percentages suggest stronger allergic sensitization and greater risk of significant reactions upon exposure.

This test detects IgE antibodies against hazelnut pollen (Corylus avellana) in your blood. Hazelnut is a tree that releases allergenic pollen in early spring. A positive result suggests your immune system reacts to hazelnut pollen, causing seasonal allergic symptoms like sneezing, nasal congestion, and itchy eyes. Hazelnut pollen allergy often occurs alongside birch pollen allergy due to cross-reactivity. This test helps identify spring pollen allergies and guides allergy management strategies.

This test detects IgE antibodies against hazelnut proteins, indicating a potential tree nut allergy. Hazelnut allergies can range from mild oral itching (oral allergy syndrome) to severe systemic reactions. People with birch pollen allergies often have cross-reactivity with hazelnuts and other tree nuts. A positive result confirms hazelnut allergy and may indicate sensitivities to related nuts. Given that nut allergies can be severe and potentially life-threatening, positive results require careful label reading, dietary avoidance, and possibly carrying an epinephrine auto-injector.
