The secretin stimulation test measures the ability of the pancreas to respond to a hormone called secretin. The small intestine produces secretin when partially digested food into the area from the stomach.
Pancreatic function test
How the test is performed
The doctor inserts a tube through your nose and into your stomach. The tube is then moved into the first part of the small intestine (
How to prepare for the test
You will be asked to not eat or drink anything, including water, for 12 hours before the test.
How the test will feel
You may have a gagging feeling as the tube is inserted.
Why the test is performed
Secretin causes the pancreas to release a fluid that contains digestive enzymes. These enzymes break down food and help the body absorb nutrients.
The secretin stimulation test is done to check the digestive function of the pancreas. The following diseases may prevent the pancreas from working properly:
In these conditions, there may be a lack of digestive enzymes or other chemicals in the fluid that comes from the pancreas. This can reduce the body’s ability to digest food and absorb nutrients.
Normal value ranges may vary slightly depending on the lab doing the test. Talk to your doctor about the meaning of your specific test results.
What abnormal results mean
Abnormal values may mean that the pancreas is not working properly.
What the risks are
There is a slight risk of the tube being placed through the windpipe and into the lungs, instead of through the esophagus and into the stomach.
