Study Summary
The purpose of this study is to analyze nasal samples for the presence of biomarkers of allergic inflammation as well as cold and flu infections, and compare these samples both in and out of an individual's active allergy season. 40 subjects who suffer from seasonal allergies will be recruited and seen both in and out of allergy season, and 10 healthy controls. Nasal epithelial lining fluid (NELF,) collected by placing small filter papers into the nostrils, blood for analysis and a cold/flu swab will be collected at each study visit.
Primary Outcome
NELF will be collected from volunteers with a history of seasonal allergic rhinitis. ECP concentration in NELF (ng/mL) will be compared between samples obtained during symptomatic periods (during their relevant allergy season) vs those obtained during asymptomatic periods
