Allergen, Individual-Food Hazelnut Corylus avellana F17

The Allergen, Individual-Food Hazelnut (Corylus avellana) F17 test is a targeted laboratory assay that measures specific IgE antibodies to hazelnut proteins in a blood sample. Performed through at‑home sample collection and analysed at a UAE‑certified laboratory, the test provides quantitative, clinician‑ready results to help identify sensitisation to hazelnut and inform allergy management in Dubai and across the UAE.

This test is useful for anyone with suspected allergic reactions after eating hazelnuts, for assessment of nut sensitisation in people with eczema or other atopic conditions, and to guide dietary advice or specialist referral. Results indicate sensitisation (specific IgE levels) but must be interpreted alongside clinical history — a positive result does not always predict the severity of reactions and may require supervised oral food challenge or specialist consultation for definitive diagnosis. In case of current or recent anaphylaxis or severe reactions, seek emergency care rather than waiting for test results.

• Hazelnut (Corylus avellana) specific IgE (kU/L)
• Quantitative specific IgE value
• Result interpretation (sensitisation class / qualitative report)

• After immediate allergic symptoms (hives, swelling, wheeze) following hazelnut ingestion
• Oral allergy symptoms such as mouth or throat itching after eating hazelnut
• Persistent or worsening eczema where nut sensitisation is suspected
• History of reactions to mixed nuts and need to identify the specific trigger
• Before reintroducing hazelnut into the diet after a period of avoidance (under clinician guidance)

• Convenient at‑home blood collection with Dubai delivery to a UAE‑certified lab
• Quantitative, clinician‑ready specific IgE report to support diagnosis and management
• Helpful for personalized dietary guidance and specialist referral planning
• Reduces need for immediate clinic visits for initial screening

• At‑home capillary blood collection (finger‑prick) or booked phlebotomy visit for sample
• No fasting required; antihistamines do not affect blood specific IgE testing
• Do not perform during an acute severe allergic reaction—seek emergency care first
