Chymotrypsin in Stool
This test measures the amount of chymotrypsin in a stool (poop) sample. Chymotrypsin is an enzyme, a protein that speeds up certain chemical reactions in your body. It is released by your pancreas (an organ behind your stomach) to help break down the protein in your food during digestion. If your pancreas is working as it should, there will be some chymotrypsin in your stool sample.
What it is for
A chymotrypsin in stool test is used to check for pancreatic insufficiency. Knowing whether or not you have pancreatic insufficiency can help your health care provider diagnose certain conditions that can cause it, such as pancreatitis and cystic fibrosis. It can also help in diagnosing the cause of malnutrition , a condition in which your body does not get the calories, vitamins , and/or minerals needed for good health.
