Tough question.: Pt's with frequent, severe or refractory ulcers are all suspects. First tests are done to prove that the high gastrin levels are due to gastrinoma, like the secretin stimulation test. Next the tumor is localized with spect scanning and other imaging tests.

Imaging ; Labs: Gastrinoma is diagnosed by laboratory and imaging tests. Octreotide scan is often helpful for localization.
