Clinical Utilities
Diagnose Zollinger-Ellison (Z-E) syndrome; diagnose gastrinoma. Gastrin >1000 pg/mL with gastric acid hypersecretion (basal acid secretion >15 mmol/hour in a patient with peptic ulcer who has not had surgery) establishes unequivocally the diagnosis of the Zollinger-Ellison syndrome.4 Antral G-cell hyperplasia may relate to high gastrin levels and duodenal ulcer.
