Populus fremontii Ab.IgE

This test detects IgE antibodies to western cottonwood tree pollen, a major environmental allergen in western North America. Cottonwood pollen triggers seasonal allergic rhinitis and asthma in sensitive individuals, causing sneezing, congestion, and respiratory symptoms during spring. A positive test confirms cottonwood sensitivity and helps explain seasonal allergy patterns. Results guide timing of allergy medications, use of air filters, and consideration of immunotherapy during high pollen seasons.
