[Modern evaluation of the accuracy of determination of the acid-forming function of the stomach by the method of intragastric pH-metry].
Described are the results of research of how the standard location (antral region-stomach body-cardium) of the comparison electrode in the 3-electrode probe affects the clinical evaluation of the acid-forming function of the stomach (AFC) in patients with gastric and duodenal ulcer. It was found that a sufficient accuracy (+/-0.2) in measurements of basal pH of the stomach body and, consequently, in clinical evaluation of AFC for the main standard locations is ensured by pH-probes with the chlorosilver skin comparison electrode.
