Overview
An elevated concentration of fasting serum gastrin level and secretin stimulation test may be helpful in the diagnosis of Zollinger-Ellison syndrome.
Laboratory Findings
- Serum gastrin measurements with calcium and especially with secretin challenge is the most important method of diagnosis. [1]
- Patients, with acid hypersecretion, who have high serum gastrin levels that remain high or further elevate on secretin infusion, should be suspected to have Zollinger-Ellison syndrome. [1]
- Laboratory findings consistent with the diagnosis of Zollinger-Ellison syndrome include:[2][3][4][5]
- Fasting serum gastrin level:
- Gastrin level ≥ 120 pg/mL
- For accurate results, gastric antisecretory medications should be stopped
- Serum calcium:
- Increased levels of serum calcium may be suggestive of multiple endocrine neoplasia type 1 (MEN1)
- Gastric acid secretion tests:
- Basal acid output
- Basal gastric secretory volume
- Gastric pH ≤ 2 is highly suggestive of Zollinger-Ellison syndrome
- Provocative tests:
