Silver birch (Betula pendula Roth.), also known as warty birch (Betula verrucosa Ehrh.), is a tree of the birch family (Betulaceae). The test determines sensitization to the Bet v2 profilin protein and Bet v4 polcalcin – the main allergenic components of birch pollen. These proteins have high cross-reactivity with other pollen allergens and plant-based foods, which is important for diagnosing polysensitization.

Bet v2 – profilin protein weighing 13–14.4 kDa, a minor allergenic component of birch pollen, causing allergic reactions in about 10% of patients. Profilin has high cross-reactivity with pollen allergens from grasses, trees, as well as plant-based foods (apple, celery, cherry, nuts, etc.).

Bet v4 – polcalcin protein weighing 9.3 kDa, a minor allergenic component causing reactions in about 20% of patients. Polcalcin also has high cross-reactivity with pollen from other plants, making it an important marker of polysensitization and aiding in the selection of immunotherapy.

  • Diagnosis of allergic reactions to birch pollen.
  • Assessment of sensitization level and risk of allergy development.
  • Monitoring the effectiveness of ongoing therapy.
  • Evaluation of sensitization level after allergen avoidance.
  • Assessment of immune system status.

FEIA (Fluorescence Enzyme Immunoassay, ImmunoCAP) – quantitative determination.

Please note that the research method and reference values may vary depending on the equipment and test systems used.

  • Blood should be drawn in the morning on an empty stomach or 4 hours after eating.
  • Drinking plain still water is allowed.
  • Do not smoke for 30 minutes before the test.
  • For children under 1 year – no food 30-40 minutes before the test; for children aged 1-5 years – 2-3 hours fasting.
