GASTRIN
2,000.00
It’s a simple blood test that checks for excess gastrin production. Gastrin is a hormone that your stomach makes to fuel the release of gastric acid. Your body needs this to digest and absorb nutrients in your food, particularly proteins and amino acids. Your stomach makes 2 to 3 liters of acidic fluid a day.
Gastric acid is found inside cells called G cells. These are located in your stomach lining and in the lining of your upper small intestine.
