Hazel Pollen Allergy Test (IgE) — Detect Winter and Early Spring Allergy
Hazel pollen is a common cause of seasonal allergies in winter and early spring in Sweden. Hazel usually flowers between January and April, depending on where you live. Because it blooms so early, hazel pollen allergy is often confused with a common cold. This IgE blood test helps confirm whether your symptoms are truly allergic in nature.
Why Test Hazel Pollen Allergy?
The test is recommended if you experience a runny or blocked nose, sneezing, itchy eyes or nose, or asthma-like symptoms early in the year. Testing helps confirm the cause and guide appropriate treatment or allergy management.
What Do High Hazel Pollen Allergy Levels Mean?
High IgE levels suggest an allergic reaction to hazel pollen. A positive result supports the diagnosis and helps guide treatment with antihistamines or allergy immunotherapy.
What Do Low Hazel Pollen Allergy Levels Mean?
Low IgE levels speak against hazel allergy, but results must be interpreted alongside symptoms. A clinical allergy may still exist even if IgE levels are low.
Symptoms to Watch For
- Runny or blocked nose in winter or early spring
- Frequent sneezing
- Itchy eyes or nose
