Enzyme-linked immunosorbent assay (ELISA) is the most commonly used serologic test for Helicobacter pylori. This study aimed to investigate the effects of age and atrophic gastritis on the diagnostic accuracy of an immunoglobulin G (IgG) antibody test against H. pylori in adults. ⋯ The quantitative ELISA test is a good noninvasive test even in older age groups and is a suitable test in patients with atrophic gastritis due to its excellent sensitivity.
