Serum and nasal lavage fluid eosinophil-derived neurotoxin levels and their determinants in adults
Background: Eosinophil-derived neurotoxin (EDN), an eosinophil granule protein, is a candidate biomarker in asthma to reflect eosinophilic activation. Objective: We sought to characterize the distribution of serum and nasal lavage fluid (NLF) EDN levels in different adult population subgroups and assess the determinants of high EDN levels. Methods: Serum and NLF samples were collected from a popul
