Normal Values:

Normal values are generally less than 100 pg/mL (picograms per milliliter).

Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

What abnormal results mean:

Too much gastrin causes severe peptic ulcer disease. Greater than normal levels may also be due to:

• Chronic atrophic gastritis
• G-cell hyperplasia (overactivity of gastrin-producing cells in the stomach)
• Use of antacids or other acid-suppressive medications
• Zollinger-Ellison syndrome, a gastrin-producing tumor that may develop in the stomach or pancreas
