Abstract excerpt
BACKGROUND & AIMS: A new gene expression profile test may distinguish eosinophilic esophagitis (EoE) and gastroesophageal reflux disease (GERD), but the optimal tissue preparation and biopsy location are unknown. We aimed to determine if formalin-fixed paraffin-embedded (FFPE) and RNA-later (RNAL) preserved specimens from newly diagnosed EoE patients have equivalent gene expression scores and whether scores vary...
