Stool testing for fat and pancreatic elastase assesses which of the following?

Stool testing for fat and pancreatic elastase assesses which of the following?

• A. Fat malabsorption and pancreatic exocrine insufficiency.
• B. Steatorrhea indicates malabsorption but elastase is unrelated.
• C. Stool tests are not useful in suspected malabsorption.
• D. Stool testing only assesses liver function.

Answer: (D)

The main idea here is that stool testing for fat and pancreatic elastase is used to evaluate fat malabsorption and pancreatic exocrine function. When fat isn’t absorbed properly, it appears in stool as steatorrhea, which fecal fat testing quantifies. Pancreatic elastase in stool reflects the amount of enzyme the pancreas is delivering to the gut; low levels indicate pancreatic exocrine insufficiency, meaning the pancreas isn’t producing enough enzymes to digest fats effectively. So, together, these tests point to fat malabsorption caused by pancreatic insufficiency. If elastase is normal while fat is malabsorbed, the issue may lie elsewhere (such as bile salt deficiency or mucosal disease), not in the pancreas. Liver-function tests, by contrast, assess hepatobiliary health (like bilirubin and liver enzymes), not pancreatic exocrine output in stool.
