Test Background
Gastrin is a naturally occurring hormone whose major physiological role is the stimulation of gastric acid secretion. Abnormally high plasma levels of gastrin may indicate Zollinger-Ellison syndrome (along with proven excessive gastric acid secretion). This is of particular interest in patients with persistent ulcer symptoms and also those with suspected familial multiple endocrine neoplasia type 1.
