The gastrin test is primarily used to help detect excess production of gastrin and gastric acid. It is used to help diagnose gastrin-producing tumors called gastrinomas, Zollinger-Ellison (ZE) syndrome, and hyperplasia of G-cells. G-cells are specialized cells in the stomach that produce gastrin, which in turn increases the production of gastric acid.A gastrin test may also be used to monitor for recurrence following the surgical removal of a gastrinoma.A gastrin stimulation test therefore may be used to provide additional information if the initial gastrin test result is moderately but not significantly elevated and the healthcare practitioner suspects that a person's symptoms are due to a gastrinoma. This procedure involves collecting a baseline gastrin sample, giving the patient a chemical (typically the hormone secretin) to stimulate gastrin production, and then collecting additional blood samples at timed intervals for gastrin testing. The other (benign) causes of elevated gastrin will not show an increase after secretin administration.A measurement of gastric acid pH level may sometimes be ordered along with or following a gastrin test to help diagnose ZE syndrome.
