Tests of gastric acidity are used to screen for the ability of the parietal cells in the stomach to produce hydrochloric acid. They are also used as an indicator of increased acid production by a patient with symptoms of peptic ulcer, to support a hypersecretory state characteristic of Zollinger-Ellison syndrome, to determine the completeness of vagotomy and to aid in the differential diagnosis of gastric ulcer from duodenal ulcer. The finding of achlorhydria (anacidity, pH > 7.0) is strong evidence of pernicious anemia.
