Birch Pollen Allergy Test (IgE) — Confirm Spring Allergy Triggers

Birch pollen is one of the most common causes of seasonal allergies in Sweden, with the main pollen season running from April to June. The allergen Bet v 1 is responsible for most birch pollen reactions and is also linked to cross-reactions with certain foods such as apples, carrots, and nuts (oral allergy syndrome). This IgE blood test helps confirm whether your immune system reacts to birch pollen.

Why Test Birch Pollen Allergy Test?

This test is relevant if you experience sneezing, watery or itchy eyes, nasal congestion, or a runny nose during spring. It can confirm a birch pollen allergy, guide treatment decisions such as antihistamines or nasal sprays, and evaluate the need for allergy immunotherapy (allergen-specific vaccination).

What Do High Birch Pollen Allergy Test Levels Mean?

High IgE levels suggest a birch pollen allergy. This may also be linked to cross-reactions with foods such as apples, carrots, hazelnuts, or celery (oral allergy syndrome), where the immune system mistakes similar food proteins for birch pollen.

What Do Low Birch Pollen Allergy Test Levels Mean?

Low IgE levels make birch pollen allergy less likely. However, other tree pollens such as alder, hazel, or oak may still be causing your spring symptoms and should be tested separately.

Symptoms to Watch For

  • Frequent sneezing during spring
  • Watery, itchy, or red eyes
  • Nasal congestion or runny nose
  • Itchy throat or mouth
  • Tingling or itching when eating raw apples, carrots, or nuts
  • Worsening of asthma symptoms in spring

Who Should Get Tested?

  • People with recurring spring allergy symptoms
  • Individuals who suspect oral allergy syndrome
  • Those considering allergy immunotherapy (vaccination)
  • Anyone who wants to identify specific pollen triggers

Frequently Asked Questions

What is oral allergy syndrome?
Oral allergy syndrome (OAS) is a cross-reaction where birch pollen-allergic individuals experience tingling, itching, or swelling when eating certain raw fruits, vegetables, or nuts — such as apples, carrots, or hazelnuts — because these foods contain proteins similar to Bet v 1.
When is birch pollen season in Sweden?
Birch pollen season typically runs from mid-April to early June, with peak levels in late April to May depending on the region.
Can allergy immunotherapy help with birch allergy?
Yes. Allergen-specific immunotherapy (ASIT) can desensitise the immune system to birch pollen over time and may also reduce oral allergy syndrome symptoms.
