The pH value is a measure of hydrogen ion concentration. A variety of disease processes can alter pH values. Determining the pH value of a body fluid may help characterize the nature of the fluid.
Gastric fluid pH can help determine if acid production in the stomach is normal.
Normal gastric fluid has a pH <3.5; any higher pH is abnormal.
