Sample

Blood draw or sample collection at a local center

A Nut and Seed Allergy Panel uses a single blood sample to screen for allergen-specific IgE antibodies against several tree nuts, peanut, and sesame. IgE is the antibody class the immune system may create after sensitization to a food protein. Nuts and seeds often appear together in foods, so a panel can help when reactions are hard to pin to one ingredient. The results are a screening tool, not a diagnosis, and a healthcare provider interprets them with your symptom history and any prior reactions.

• Almond-specific IgE Antibodies against almond proteins; assesses sensitization to this tree nut.
• Cashew-specific IgE Antibodies against cashew proteins; a tree nut marker on the panel.
• Coconut-specific IgE Antibodies against coconut proteins; included for suspected coconut reactions.
• Hazelnut-specific IgE Antibodies against hazelnut proteins; a common tree nut marker.
• Pecan-specific IgE Antibodies against pecan proteins; another tree nut screened on the panel.
• Peanut-specific IgE Antibodies against peanut proteins; peanut is a legume rather than a tree nut.
• Sesame seed-specific IgE Antibodies against sesame proteins; screens for seed sensitization.

• People who react with hives, itching, or swelling after eating nuts or seeds
• Individuals with mouth tingling or throat irritation after nut-containing foods
• Those with digestive symptoms following mixed nut or seed products
• People with eczema who suspect a nut or seed trigger
• Anyone who has had a reaction and needs several nut markers checked together

• No fasting is required for this IgE panel
• Collect the sample at any time of day
• Tell the provider about medications you are taking
• Hydration beforehand can ease the blood draw

Each nut and seed on the panel is reported with its own IgE level or class. A value above the reporting threshold may indicate sensitization to that allergen, but sensitization does not always cause symptoms. Low or undetectable levels make allergy to that specific nut or seed less likely without fully ruling it out. Because peanut is a legume and coconut is botanically a fruit, a provider interprets each marker separately. Discuss results with a healthcare provider before removing foods from your diet.
