Allergen, Individual-Tree pollen Hazel Corylus Avellana T4

The Allergen, Individual-Tree pollen Hazel (Corylus avellana) T4 is an at‑home blood test that detects sensitization to hazel pollen by measuring specific IgE antibodies directed against Corylus avellana. Collected via a capillary finger‑prick or home phlebotomy and analysed in a certified laboratory, the assay provides quantitative sIgE levels and a sensitization class to help identify whether hazel pollen is a likely trigger for seasonal allergic rhinitis, conjunctivitis, or asthma.

This test is useful for people who experience recurrent seasonal allergy symptoms, unexplained respiratory or ocular allergy signs during the hazel pollen season, or for patients and clinicians considering allergen immunotherapy. Results support personalised management in Dubai by guiding avoidance measures, selection of pharmacotherapy, and decisions about starting or tailoring allergen immunotherapy under a UAE‑licensed allergist’s supervision.

Sample collection requires minimal preparation (no fasting) and is compatible with home collection services in Dubai; antihistamines do not affect sIgE measurements, but inform the collection team about recent biological therapies or ongoing allergen immunotherapy which may influence interpretation. Laboratory reports typically provide numeric sIgE values (kU/L) and an interpretation band (sensitization class); remember that a positive sensitization does not always equal clinical allergy, so results should be reviewed with a healthcare professional for diagnosis and treatment planning.

• Hazel (Corylus avellana) pollen-specific IgE (sIgE)
• sIgE concentration (kU/L)
• Sensitization class / Allergen interpretation (Class 0–6)

• Recurrent seasonal sneezing, nasal congestion, or itchy/watery eyes during tree pollen season
• Seasonal asthma exacerbations or wheeze with suspected pollen trigger
• Before initiating allergen-specific immunotherapy for tree pollen allergies
• Persistent allergy symptoms despite over-the-counter treatments
• To differentiate hazel pollen sensitization from other tree or pollen allergens

• Accurate laboratory-based detection of sensitization to hazel pollen from a home-collected sample
• Quantitative results to guide clinical decisions and monitoring
• Supports personalised avoidance strategies and medication planning
• Helps determine eligibility and target for allergen immunotherapy
• Convenient at-home collection with reporting suitable for follow-up with Dubai allergists

• At‑home blood sample collection (finger‑prick capillary or venous draw by trained collector)
• No fasting required prior to sample collection
• Inform the collector about current immunotherapy, biologic treatments, or recent transfusions
