What is serum gastrin levels?

The average normal level of fasting serum gastrin is about 50 pg per ml, and ranges from 20 to 100 pg. The upper limit of normal is 200 pg, and in the presence of gastrinoma (Zollinger-Ellison syndrome), fasting levels may rise to over 7,000 pg (70–80 percent, G 34).

What is high gastrin levels?

Abnormal gastrin production occurs in some clinical and diseased states, a condition known as hypergastrinemia and defined by a Gastrin level greater than 100–150 pg/ml [2].

What is a gastrin blood test used for?

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.

What causes high serum gastrin?

By far, the two most common causes of high gastrin levels are anti-acid medications you take for reflux or heartburn and a condition called chronic atrophic gastritis. These both can do damage to your stomach lining. They also cause your stomach to make less acid.
