I do believe this is the test she is talking about ...am I correct Mom2Sophia?? After a period of fasting, fluid is all that remains in the stomach. This fluid can be removed via a tube inserted through the esophagus (food pipe). To test the ability of cells in the stomach to secrete acid, gastrin may be injected just under the skin, into a muscle, or into a vein. The stomach contents are then removed and analyzed. Another test involves insulin-induced hypoglycemia . Enough insulin is given under the skin or through a vein to cause the blood sugar to decrease. This causes the vagus nerve to stimulate the release of gastrin. After a short time, the stomach contents are removed and analyzed.
