Trypsinogen is a substance that is normally produced in the pancreas and released into the small intestine. Trypsinogen is converted to trypsin. Then it starts the process needed to break down proteins into their building blocks (called amino acids).
A test can be done to measure the amount of trypsinogen in your blood.
How is the Test Performed?
A blood sample is taken from a vein. The blood sample is sent to a lab for testing.
Preparation for the Test
There are no special preparations.
How the Test will Feel
You may feel slight pain or a sting when the needle is inserted to draw blood. Afterward, there may be some throbbing.
Why is the Test Performed?
This test is done to detect diseases of the pancreas.
The test is also used to screen newborn babies for cystic fibrosis.
Normal Results for Trypsinogen test
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What Abnormal Results Mean
Increased levels of trypsinogen may be due to:
- Abnormal production of pancreatic enzymes
- Acute pancreatitis
- Cystic fibrosis
- Pancreatic cancer
Low or normal levels may be seen in chronic pancreatitis.
Trypsinogen test Risks
Veins and arteries vary in size so it may be harder to get a blood sample from one person than another. Other slight risks from having blood drawn may include:
Other risks associated with having blood drawn are slight but may include:
- Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
Other tests used to detect pancreas diseases may include:
- Serum amylase
- Serum lipase
