Using 283 gastrobiopsy specimens obtained from 113 patients with chronic gastroduodenitis, Helicobacter pylori infection was diagnosed using invasive (histology, histobacterioscopy, urease helpil test) and non-invasive (breathing helix test, enzyme-linked immunosorbent test system "GastroPanel") methods. Damage to the antrum of the stomach was detected by histological method in 59.7% of patients, and by the GastroPanel method - in 36.6%. Changes in the fundus were diagnosed by histological method in 20.5% of the observed patients, and by the GastroPanel method - in 17.6%.
