Gastrin details
What Gastrin shows
Gastrin is a hormone produced mainly in the stomach that stimulates the release of stomach acid to aid digestion. Elevated gastrin can occur with conditions that block normal acid-related feedback, most notably Zollinger-Ellison syndrome, a rare condition caused by a gastrin-producing tumor that leads to severe acid overproduction and recurrent ulcers, and is also commonly elevated simply from taking acid-suppressing medications (like proton pump inhibitors), which remove the normal feedback signal that would otherwise keep gastrin in check. Because of this medication effect, gastrin testing sometimes requires stopping certain acid-reducing drugs beforehand for an accurate result.
Tests that include Gastrin
This test measures the level of gastrin in the blood. It is primarily used for diagnosing and monitoring gastrin-secreting tumors, such as gastrinomas, which are associated with Zollinger-Ellison syndrome. Elevated gastrin levels can also indicate conditions like gastric ulcers or pernicious anemia. It is a valuable tool in the differential diagnosis of hypergastrinemia-related disorders.
- Gastrin A hormone that stimulates stomach acid production. Elevated levels can indicate conditions like Zollinger-Ellison syndrome or chronic acid-suppressing medication use.
