“…Catheter or capsule based intragastric pH monitoring rely solely on spatially selective pH measurements and therefore provide only limited or no data on the dynamics, distribution and volume of gastric secretion. Aspiration and in vivo intragastric titration (7)(8)(9) , the two most common methods used to quantify gastric acid secretion are both invasive and may themselves influence the rate and dynamics of secretion (6). Also, catheter migration is an additional problem potentially leading to inaccuracies (6).…”

“…Actually, in 4 subjects who repeated the Ca 13 CO 3 breath test three times without gastric stimulants, the test results considerably varied with the CV of 0.25 (data not shown). To enhance the reproducibility, usage of a gastric acid stimulant such as test meals or drugs have been reported (Kay 1953;Ward et al 1963;Lawrie and Forrest 1965). In particular, pentagastrin has frequently been used as a gastric acid stimulant in gastric secretory testing.…”

“…After aspiration, the acidity of the gastric acid can be derived by titration to a pH 7 using an alkaline solution and chemical indicators or pH meters. 16 The position of the gastric tube in the most dependent part of the stomach can be confirmed either radiologically or by a water recovery test. In the water recovery test, the subject drinks 20 mL of water and if 16-20 mL of it can be aspirated via the gastric tube, it can be taken as a marker that the tube is in a satisfactory position.…”

“…21 Initial methods of stimulating gastric acid involved the administration of test meals to subjects, following which stomach contents were aspirated and acid content was calculated by titration. 16 However, partial neutralisation of the acid by the test meal, the practical difficulties of trying to titrate food-filled gastric fluid and the fact that these tests were neither precise nor reproducible led to the development of newer techniques for measuring stimulated gastric acid secretion.…”
