Where do our pollen counts come from? Understanding the National Allergy Bureau (NAB)

Even many allergists do not know about the NAB and how it provides accurate pollen counts to patients and physicians across the country. Andrew Rorie, MD, FAAAAI, chair of the Aerobiology Committee, walks us through the NAB as well as how pollen levels are changing over time. He also discusses how you can get involved in monitoring pollen in your area. Visit the NAB.
