The National Allergy Bureau™ (NAB™) is the section of the AAAAI’s
Aeroallergen Network responsible for reporting current pollen and mold
spore levels. The Aeroallergen Network is comprised of pollen and spore
counting stations staffed primarily by AAAAI member volunteers who
generously donate their time and expertise. The NAB currently provides
the most accurate and reliable pollen and mold levels from approximately
85 counting stations throughout the United States, two counting
stations in Canada, and two counting stations in Argentina. The stations
use air sampling equipment to collect airborne pollen and spores which
are then examined microscopically. This information is also used for
research to aid in the diagnosis, treatment and management of allergic
diseases. Pollen counts from the NAB stations are based on actual
counts, which reflect the real day to day weather events. Predicted
counts reported on many websites may be based on pollen data from
previous years and general weather forecasts.
