Chymotrypsin, Stool
Also known as: Fecal Chymotrypsin
Use
The diagnosis of chronic pancreatitis depends upon the demonstration of functional impairment of the pancreas. Impairment is determined by several means, two of which are: 1. Direct measurement of exocrine secretion into the duodenum after stimulation by a standard meal or after stimulation by intravenous secretin/pancreozymin. 2. The direct measurement of the activities of certain enzymes in feces. Chymotrypsin activity in stool, for example, has been shown to be lower than normal in patients with pancreatic exocrine insufficiency.
