How is Zollinger-Ellison syndrome (ZES) diagnosed?

ANSWER

Your doctor will do a blood test to look for high levels of gastrin, the hormone made by gastrinomas. They might also test how much acid your stomach makes.

Your doctor might do an endoscopy. This is done with a flexible, lighted tube that looks at your esophagus, stomach, and small intestine.

Other tests your doctor might perform include a CT scan to get detailed images of the inside of your body, a PET scan to locate tumors, and an octreotide scan to look for neuroendocrine tumor cells.
