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.
