Pancreatitis is an inflammation of the pancreas, a large organ that sits behind the stomach and plays a role in digestion. It can cause a range of bothersome symptoms, including abdominal pain, nausea, and vomiting. In order to diagnose pancreatitis, blood tests are often performed to measure levels of certain enzymes and proteins that are released when the pancreas is inflamed. Here is a closer look at the lab tests that are typically used to diagnose pancreatitis and determine its severity.
Enzymes Elevated With Pancreatitis
The most common lab test used to diagnose pancreatitis is the measurement of amylase and lipase enzymes in the blood. These enzymes are released from the pancreas when it is inflamed and their levels in the blood can be measured to determine the severity of the inflammation. The normal range for amylase is between 25 U/L and 125 U/L, while lipase should be between 10 U/L and 60 U/L. If these levels are elevated, then pancreatitis is likely the cause.
Proteins Elevated With Pancreatitis
In addition to measuring amylase and lipase, blood tests can also be used to measure levels of certain proteins that are released when the pancreas is inflamed. These proteins include C-reactive protein (CRP) and pancreatic polypeptide (PP). Elevated levels of these proteins indicate that the pancreas is inflamed and can be used to help diagnose pancreatitis.
Other Tests
In addition to measuring blood levels of enzymes and proteins, other tests may be used to diagnose pancreatitis. These tests include imaging studies, such as an ultrasound or CT scan, to look for signs of inflammation in the pancreas. A biopsy may also be done to take a sample of pancreatic tissue to look for signs of inflammation.
In conclusion, pancreatitis is a condition that can cause a range of bothersome symptoms, including abdominal pain, nausea, and vomiting. To diagnose pancreatitis, blood tests are often performed to measure levels of certain enzymes and proteins that are released when the pancreas is inflamed. In addition, other tests, such as imaging studies and biopsies, may also be used to diagnose the condition.
