Detection of Helicobacter pylori infection by examination of human breath odor using electronic nose Bloodhound‐214ST

Our aim was to examine the possibility of use e‐nose Bloodhound‐214ST to determine presence or absence of H. pylori infection using exhalation samples of patients. Breath samples were collected twice: at baseline and after oral administration of 500 mg of urea. H. pylori status of patients was confirmed by antral biopsy. Using two approaches for the data analysis we showed the possibility to distinguish H. pylori free and infected patients.
