gastrin test

gastrin test

a blood test used to help identify patients with Zollinger-Ellison syndrome and G-cell hyperplasia who typically have high serum gastrin levels. Gastrin is a hormone that is secreted by cells of the stomach and causes secretion of hydrochloric acid. Test results can help the clinician institute appropriate, aggressive medical and surgical therapy for these patients.

Stimulated gastric acid secretion was measured, using an endoscopic gastrin test, in 89 patients (mean age, 56 years) with dyspeptic symptoms.
The cost of the serum gastrin test ($38) is reasonable, however, and the test is readily available.
Although a more rapid gastrin test has been reported recently (66), the greater length of time needed for resecting gastrinomas makes it less important to have as short of an analysis time.
