Gastrin: What To Think About
Content provided by Healthwise
What To Think About
- The level of gastrin in the blood varies throughout the day, but it is usually lowest in the morning.
- Gastrin test results are most useful when they are evaluated along with medical information gathered from other examinations or tests.
- If you have normal or mildly elevated gastrin levels but continue to have problems with peptic ulcers, further blood testing may be done. An intravenous secretin test helps determine whether peptic ulcers are being caused by Zollinger-Ellison syndrome. Gastrin levels generally increase by more than 200 picograms per milliliter (pg/mL) in people who have Zollinger-Ellison syndrome, but they rise only slightly or decrease in people who do not have the syndrome.
