Diagnosis & Tests
How is the condition diagnosed?
A person's history and physical exam may make a healthcare provider suspect Zollinger-Ellison syndrome. The most important test to help diagnose this condition is a blood test. This blood test measures the level of the hormone gastrin, which is extremely high in someone with ZES. A person with ZES also has abnormally increased amounts of stomach acid. Other special tests may also be needed when ZES is suspected.
Also, special types of x-ray tests and scans can help locate the tumor. Locating the tumor may be difficult.
