Celiac disease lateral-flow immunochromatographic assay (CD-LFIA) result compared to diagnosis of celiac disease based on elevated titers of immunoglobulin A-tissue transglutaminase (IgA-tTG) in a population including gluten-free diet (GFD), first-degree relatives (FDR) and patients with celiac disease (CD)-related symptoms and FDR and patients with CD-related symptoms only. ELISA: Enzyme-linked immunosorbent assay.
