Answer :

DefinitionGastrin is the major hormone that regulates acid secretion in the stomach. It is produced by special cells in the stomach. Small amounts of gastrin may also be produced by the pancreas and possibly the intestines. When there is food in the stomach, gastrin is released into the blood. As stomach and intestinal acidity rises, gastrin production normally decreases.A laboratory test can be done to measure the amount of gastrin in the blood.How the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider
