The aim of the study was to assess the correlation between plant pollen count and allergen-specific IgE concentration.
Specific IgE antibodies concentration was determined in 411 patients allergic to pollen. RAST/CAP Pharmacia system was used. The study was carried out in Children's Hospital in Gdansk from October 1993 till July 1995. Annual pollen fall in Gdansk was also analysed. The results obtained in Durham sampler study (1989-92) were taken into consideration.

In 1989-92 in Gdansk the conifers pollen was prevailing (32.37%). The concentration of allergen-specific IgE antibodies was the highest in the group of patients allergic to grass pollen (41.7%) and in patients allergic to late-pollinating trees (23.18%).
