Chymotrypsin in Stool

Chymotrypsin in Stool

Chymotrypsin is an enzyme that is present in the digestive system. It is created by the pancreas and is essential for the breakdown of proteins. It is also found in trace amounts in the stool of humans. A chymotrypsin stool test is used to detect elevated levels of the enzyme in the stool, which could indicate issues with the pancreas.


Before getting a stool sample for the test, your doctor might ask you to change your diet. This means that you can’t eat certain things such as caffeine and foods high in fat, sugar, or proteins. Your doctor will also ask you to stop taking any medications that could affect the results of the test.


During the procedure, your doctor will collect a sample of your stool. You may also be asked to put on a gown before the sample is taken. The sample will be tested in the lab to measure the levels of chymotrypsin in your stool. The results should be available in a few days.


  • Chymotrypsin Test – measures the amount of chymotrypsin present in the stool to help diagnose abdominal issues.
  • Chymotrypsin Assay – used to measure enzyme activity levels in order to diagnose pancreatitis.
  • Chymotrypsin Inhibition Test – measures the amount of enzyme activity in the body to help diagnose pancreatic issues.


Stool tests are generally very safe and have no known risks or side effects. However, it is important to follow the instructions provided by your doctor carefully. If you don’t, it could lead to errors in the results or a false diagnosis.

Why Is It Done?

A chymotrypsin stool test is typically done to help diagnose abdominal problems such as pancreatitis or irritable bowel syndrome (IBS). It can also be used to monitor existing conditions. It can also be used to detect discrepancies in the digestive system that might be caused by certain medications.

When Is It Done?

A chymotrypsin stool test should only be done when recommended by your doctor. It is typically done when other tests don’t provide a clear diagnosis. It is also done when existing conditions need to be monitored or treated.
