Testing was done to see whether your pancreas is producing enough substances for digestion.

The pancreas is tucked behind the stomach in the upper abdomen. The pancreas produces messenger substances. The messenger substances control the sugar level in the blood. The pancreas also produces a fluid that is released into the intestines. This fluid contains substances that are important for the digestion of fats, proteins and sugars.

The test involves examining the fluid from the pancreas. To do this, a small tube is usually pushed through the nose, the esophagus and the stomach to the duodenum. The fluid can be extracted from the pancreas through this tube. Drugs can be given during the test to get the pancreas to produce more fluid. Then testing can determine what volume of substances for digestion the fluid contains. Moreover, measurements show how much fluid, in total, the pancreas has produced during the test.
