Gastrin Blood Test

  • Certified labs

  • Digital report

A certain type of tumor called gastrinoma can cause excess gastrin production.

What is this test?

This test measures levels of gastrin in the blood. Gastrin is a hormone that is produced by cells in the stomach. When a person eats, the stomach releases gastrin which in turn stimulates the production of gastric acid which helps to digest food. When this process is functioning normally, gastrin blood levels are low. A certain type of tumor called gastrinoma can cause excess gastrin production. The excess acid produced as a result can lead to the development of ulcers which are difficult to treat. Gastrin may also be elevated in cases of certain types of anemia which cause damage to the cells in the stomach that produce acid. A gastrin test is typically ordered when someone has recurrent ulcers which do not respond to treatment along with symptoms such as diarrhea and abdominal pain. It may also be ordered when someone is suspected of having pernicious anemia due to Vitamin B12 deficiency or a malabsorption disorder.
