What is the pancreatic function test?
Pancreatic function tests are used to measure pancreatic secretion in humans. The tests are clinically useful to discriminate between pancreatic and nonpancreatic causes of malabsorption.
How do you test for pancreatic enzymes?
Enzyme secretion testing. The most accurate way to test for enzyme secretion is direct function testing. The method is to place a hose, tube or catheter at, on into the pancreatic duct, and measure pancreatic secretion for a about 90 minutes (depending on the test) after stimulating the pancreas with a hormone (e.g. CCK) or a test meal.
What is the normal range for pancreas function?
Pancreas function tests are used to assess the health of the exocrine pancreas. The pancreas function test normal values include amylase levels of 23-85 U/L and lipase levels of 0-160 U/L. Types include blood tests, MRCP, ERCP Skip to content Cancer Diabetes Ask a Doctor Children Heart Men Women General Tests & Procedures Home About us
What does a CT scan of the pancreas show?
This imaging test can help assess the health of the pancreas. A CT scan can identify complications of pancreatic disease such as fluid around the pancreas, an enclosed infection (abscess), or a collection of tissue, fluid, and pancreatic enzymes (pancreatic pseudocyst).
What blood tests are done to check pancreas function?
Lipase is the preferred laboratory test for diagnosing acute pancreatitis, as it is the most sensitive and specific marker for pancreatic cell damage. Additional laboratory testing, such as complete blood count (CBC) and lactate dehydrogenase (LDH) tests, are useful to obtain prognostic information.
What is the normal count for pancreas?
The normal range for adults younger than 60 is 10 to 140 U/L. Normal results for adults ages 60 and older is 24 to 151 U/L. Higher than normal levels of lipase mean that you have a problem with your pancreas. If your blood has 3 to 10 times the normal level of lipase, then it's likely that you have acute pancreatitis.
What is the best way to check your pancreas?
Magnetic resonance cholangiopancreatography (MRCP) The technician injects dye into the patient's veins, which helps show the pancreas, gallbladder, and pancreatic and bile ducts. This is another sensitive test for evaluating the gallbladder, bile ducts, and pancreas for causes of acute pancreatitis.
What is a healthy lipase level?
In general, normal results are 0 to 160 units per liter (U/L) or 0 to 2.67 microkat/L (µkat/L). Normal value ranges may vary slightly among different laboratories.
When should I be concerned about my pancreas?
Symptoms of chronic pancreatitis Constant pain in your upper belly that radiates to your back. This pain may be disabling. Diarrhea and weight loss because your pancreas isn't releasing enough enzymes to break down food. Upset stomach and vomiting.
What are the early signs of pancreas problems?
SymptomsUpper abdominal pain.Abdominal pain that radiates to your back.Tenderness when touching the abdomen.Fever.Rapid pulse.Nausea.Vomiting.
Do blood tests show pancreas problems?
Diagnosis Acute pancreatitis A doctor will ask you about your symptoms, family history and may feel your tummy – it will be very tender if you have acute pancreatitis. They'll also do a blood test, and sometimes a CT scan, to help confirm the diagnosis.
What test shows pancreas problems?
Blood tests to look for elevated levels of pancreatic enzymes, along with white blood cells, kidney function and liver enzymes. Abdominal ultrasound to look for gallstones and pancreas inflammation. Computerized tomography (CT) scan to look for gallstones and assess the extent of pancreas inflammation.
What level of lipase is fatal?
A fatal outcome may be predicted by simple laboratory parameters such as a high serum creatinine and blood glucose. An APACHE II score > or = 6 and a lipase level on admission > or = 1,000 U/l indicate severe pancreatitis.
What does a high lipase level mean?
Lipase helps your body digest fats. It's normal to have a small amount of lipase in your blood. But, a high level of lipase can mean you have pancreatitis, an inflammation of the pancreas, or another type of pancreas disease. Blood tests are the most common way of measuring lipase.
What is considered a high level of amylase?
The normal range for amylase in a blood sample for an adult is 30 to 110 units per liter (U/L). If your amylase levels are higher than normal, you may have 1 of many conditions. These include: Sudden swelling of the pancreas (acute pancreatitis)

What is bicarbonate secretion testing?
Bicarbonate secretion testing. Bicarbonate secretion testing is done to diagnose chronic pancreatitis. This must be done using a hose, tube or catheter that is placed at the location where the pancreas empties juice into the intestine. The pancreas is stimulated with secretin (e.g. ChiRhoStim) and the juice is collected for analysis.
Why is insulin secretion important?
Insulin secretion from the pancreatic islet cells is critical for maintaining normal blood sugar. In most clinical cases, insulin levels are not measures. Rather, the physician works on diet and medicines to keep the blood sugar in normal ranges.
What are the functions of the pancreas?
The three functions of the pancreas are to produce enzymes for digestion, to produce bicarbonate to neutralize gastric acid, and to produce insulin to signal cells in the body to begin taking nutrients out of the blood in anticipation of digestion and absorption of food. The major test include:
How to test for enzyme secretion?
Enzyme secretion testing. The most accurate way to test for enzyme secretion is direct function testing. The method is to place a hose, tube or catheter at, on into the pancreatic duct, and measure pancreatic secretion for a about 90 minutes (depending on the test) after stimulating the pancreas with a hormone (e.g. CCK) or a test meal.
How long does it take for a fecal fat test to be done?
The 72 hour fecal fat test measures the body’s ability to digest fat during three days of a high-fat diet and stool collection for measurement of fat. The difference between the amount that goes in the mouth and that comes out the bottom is called the coefficient of fat absorption (CFA).
What is the most common test for elastase?
The most popular test in clinical practice is the human fecal elastase-1 test on stool samples. This test measures one of the digestive enzymes that is normally secreted by the pancreas.
Is Pert good for pancreatic dysfunction?
This test is not so good for diagnosing pancreatic dysfunction, but is useful in proving that pancreatic enzyme replacement therapy (PERT) is effective in helping to digest fat in time for absorption, and therefore improve the CFA.
Overview
The pancreas is an organ in the back of your abdomen (belly). It is part of your digestive system.
Function
An exocrine gland runs the length of your pancreas. It produces enzymes that help to break down food (digestion). Your pancreas releases the following enzymes:
Anatomy
Your pancreas sits behind your stomach and in front of your spine. Your gallbladder, liver and spleen surround your pancreas.
Care
Maintaining a healthy weight. Regular exercise and avoiding weight gain can help prevent Type 2 diabetes and gallstones that can cause pancreatitis.
Frequently Asked Questions
If you have symptoms that don’t go away or keep coming back, you should talk to a healthcare provider. Signs of pancreas problems may include:
What test can determine if a pancreas function test is needed?
Based on the results of an amylase test, a lipase test , and your medical history, your doctor can decide if additional pancreas function tests are needed or determine what type of treatment is needed. Medically Reviewed By.
What is the purpose of a pancreatic test?
This test may be performed to determine the activity of the pancreas in people with diseases that affect the pancreas (for example, cystic fibrosis or pancreatic cancer).
What is the blood test for gallbladder?
Blood Tests. Blood tests can evaluate the function of the gallbladder, liver, and pancreas. Levels of the pancreatic enzymes amylase and lipase can be measured. Blood tests can also check for signs of related conditions, including infection, anemia ( low blood count ), and dehydration. A tumor marker called CA 19-9 may be checked ...
What is the purpose of secretin stimulation test?
The secretin stimulation test measures the ability of the pancreas to respond to secretin.
What is the purpose of a CT scan of the pancreas?
This imaging test can help assess the health of the pancreas. A CT scan can identify complications of pancreatic disease such as fluid around the pancreas , an enclosed infection (abscess), or a collection of tissue, fluid, and pancreatic enzymes (pancreatic pseudocyst).
What does an abdominal ultrasound show?
An abdominal ultrasoundcan detect gallstones that might block the outflow of fluid from the pancreas. It also can show an abscess or a pancreatic pseudocyst.
Where is lipase released?
The pancreas makes lipase to digest fats into fatty acids. Sugars and fatty acids can then be absorbed by the small intestine. Some amylase and lipase can be found in saliva and in the stomach. However, most of the enzymes made in the pancreas are released into the small intestine. The values of pancreas function test include normal amylase levels ...
Assessment
- The fecal elastase test measures elastase, an enzyme found in fluids produced by the pancreas. Elastase digests and degrades various kinds of proteins. During this test, a patient's stool sample is analyzed for the presence of elastase.

Example
- Pancreas function tests are most commonly used to diagnose chronic pancreatitis. These include tests which document exocrine or endocrine gland insufficiency and tests which instead measure gradations of decreased secretory capacity. Blood tests can evaluate the function of the gallbladder, liver, and pancreas. Levels of the pancreatic enzymes amyl...
Mechanism
- Secretin is a hormone made by the small intestine and It stimulates the pancreas to release a fluid that neutralizes stomach acid and aids in digestion. The secretin stimulation test measures the ability of the pancreas to respond to secretin.
Clinical significance
- This test may be performed to determine the activity of the pancreas in people with diseases that affect the pancreas (for example, cystic fibrosis or pancreatic cancer).
Symptoms
- During the test, a health care professional places a tube down the throat, into the stomach, then into the upper part of the small intestine. Secretin is administered by vein and the contents of the duodenal secretions are aspirated (removed with suction) and analyzed over a period of about two hours.
Causes
- In an ERCP, a health care professional places a tube down the throat, into the stomach, then into the small intestine. Dye is used to help the doctor see the structure of the common bile duct, other bile ducts, and the pancreatic duct on an X-ray. If gallstones are blocking the bile duct, they may also be removed during an ERCP.
