What is a pancreatic elastase stool test for?
A stool elastase test is used to find out if there is pancreatic insufficiency. This test is better at finding severe pancreatic insufficiency, rather than mild or moderate cases. Pancreatic insufficiency can sometimes be a sign of pancreatic cancer, but this test is not used to screen for or diagnose cancer.

What does pancreatic insufficiency poop look like?
Symptoms of Pancreatic Exocrine Insufficiency The stools tend to be oily, large, pale, very foul-smelling, and often float in toilet water and stay in the toilet bowl, even after flushing. Individuals with steatorrhea sometimes experience fecal incontinence or oily leakage.
Can stool elastase be too high?
A level that’s too high is a sign of a problem. Fecal elastase test. You’ll give your doctor a solid stool sample.
How do you interpret faecal elastase?
Interpretation: Faecal elastase is reduced in pancreatic exocrine failure. Malabsorption is not usually obvious until > 95% of the pancreas has been destroyed. Values of 100-200 µg/g indicate moderate, and < 100 µg/g severe, pancreatic insufficiency.
Is fecal elastase accurate?
Diagnostic accuracy was 92% for fecal EL-1 and 82% for FCT. Steatocrit values were over the normal limit in 11 patients with small intestine diseases; in 7/11 of these patients at least one of the pancreatic test results was below the normal limit.

Can a stool sample detect pancreatitis?
Measuring pancreatic elastase to diagnose pancreatic disease has become a more common practice by clinicians. Stool pancreatic elastase levels can help determine exocrine pancreatic function. The Pancreatic Elastase ELISA is a tool to confidently measure levels of pancreatic elastase in human stool samples.
What does 500 mean for pancreatic elastase?
PE1 levels greater than 200 mcg/g and less than 500 mcg/g suggest a deviation from optimal pancreatic function, values between 100 and 200 mcg/g suggest moderate pancreatic insufficiency, and values less than 100 mcg/g are considered to be consistent with severe pancreatic insufficiency. 53,54.
How accurate is pancreatic elastase?
The test assesses the pancreatic status with 92.8% sensitivity and 96.6% specificity in comparison to classical ELISA fecal elastase-1 test for all subjects studied.
What color is stool with pancreatitis?
Chronic pancreatitis, pancreatic cancer, a blockage in the pancreatic duct, or cystic fibrosis can also turn your stool yellow. These conditions prevent your pancreas from providing enough of the enzymes your intestines need to digest food.
What does a pancreatic elastase test show?
The test measures the levels of elastase, an enzyme found in fluids produced by the pancreas. Elastase digests (breaks down) proteins. In this test, a patient’s stool sample is analyzed for the presence of elastase. This imaging test can help assess the health of the pancreas.
What does low pancreatic elastase mean?
Elastase is an enzyme that breaks down protein. Low levels of elastase or high levels of fat in your stool mean that you may have a problem with your pancreas. Pancreatic function. Your provider will stimulate your pancreas to make fluid. He or she will then collect it from your small intestine.
What lab test is used for pancreatitis?

However, blood tests are not typically used to make the diagnosis of chronic pancreatitis.
What does pancreatic elastase do?
Pancreatic elastase is a protein produced by the pancreas to help break down food remains. A pancreas that is not performing correctly may cause bloating and watery stools. The pancreas gland produces pancreatic elastase, a protein that aids in digestion. Elastases are members of a family of serine proteases.
