Loyola Medicine Allergy Count: Pollen Forecast & Allergy Info

Loyola Medicine Allergy Count

The most recent count for pollen and spores are listed beneath the table below.

The Loyola Medicine Allergy Count, under the direction of Rachna Shah, MD, reports pollen counts each weekday morning in Melrose Park. Pollen samples are gathered every weekday morning (during allergy season, March to October) from the roof of the Gottlieb Professional Building. Pollen grains and spores are collected from a cubic meter sample of air and counted under a microscope.

Besides appearing on our website, the counts are also available each morning by 7:30 am on a telephone hotline: 1-866-4-POLLEN (1-866-476-5536).
