Pollen Information: Pollen Counts
Pollen and mold counts measure the amount of airborne allergens present in the air. Counts are compiled by a variety of methods. Pollen and mold spore counts can be determined daily, and are reported as grains per cubic meter of air. Certified aeroallergen counters at many universities, medical centers and clinics provide these counts on a volunteer basis.
The National Allergy Bureau� (NAB�) is the nation's only pollen and mold counting network certified by the AAAAI. As a free service to the public, the NAB compiles pollen and mold counts from certified stations across the nation and reports them to the media three times each week. These counts are also available on the NAB page of the AAAAI's Web site, www.aaaai.org.
Interpretation of pollen and mold counts and their relationship to symptoms is complex. Sampling techniques such as the type of device used and its location within the community can affect counts. While many patients develop symptoms when pollen counts are 20-100 grains per cubic meter, one's symptoms may also be affected by recent exposure to other allergens, the intensity of pollen exposure, and individual sensitivity. Pollen counts reported to the public are generally taken the preceding one to three days, and may vary widely from day to day during a season. Overall, the use of pollen counts in predicting symptom severity in a given individual is somewhat limited.
