Gastrin Stimulation Test by Secretin

Gastrin Stimulation Test by Secretin

The gastrin stimulation test by secretin is a diagnostic procedure designed to measure the level of gastrin in your blood after an injection of secretin, a hormone that naturally stimulates the pancreas to release bicarbonate. The test is primarily used to diagnose certain medical conditions, such as gastrinomas and Zollinger-Ellison syndrome, both of which can lead to high gastrin levels.


  • Test Name Gastrin Stimulation Test by Secretin
  • Sample Type Blood
  • Preparations Required Fasting is typically required for this test. You should not eat or drink anything other than water for 8-12 hours prior to the test. Certain medications may affect gastrin levels, so it is crucial to inform your doctor about any medications you are currently taking.

Gastrinomas are tumors that produce gastrin and can be found in the pancreas or the small intestine. Zollinger-Ellison syndrome is a condition caused by gastrinomas and can lead to stomach ulcers due to the excessive production of stomach acid.

This is a blood test that measures the level of the hormone gastrin before and after an injection of secretin. It helps diagnose conditions that cause excessive stomach acid production.

This test is performed when a patient has symptoms suggestive of gastrinomas or Zollinger-Ellison syndrome. Symptoms may include recurrent peptic ulcers, diarrhea, and gastroesophageal reflux disease (GERD).

Blood samples are collected before and after an injection of secretin. The secretin causes the pancreas to produce bicarbonate, and in response, gastrin levels should remain the same or decrease. If gastrin levels increase significantly, this may indicate a problem such as a gastrinoma.

High levels of gastrin following secretin injection may indicate the presence of a gastrinoma or Zollinger-Ellison syndrome. Normal or decreased levels of gastrin suggest that the pancreas and stomach are functioning correctly.

Risks associated with the gastrin stimulation test by secretin are minimal but may include slight discomfort or bruising at the site of blood draw. Side effects from the secretin injection are rare but can include nausea, flushing, or lightheadedness.

Your doctor will discuss the test results with you. If the results are abnormal, further testing may be required to confirm the diagnosis and determine the most appropriate treatment.
