1. Pancreatic Function Tests
Pancreatic function tests are used to diagnose chronic pancreatitis and measure the severity of the condition. Common tests used to evaluate pancreatic function include:
a. Fecal Elastase Test: This test measures the amount of elastase, an enzyme made by the pancreas, in the stool. Low levels of elastase indicate that the pancreas is not able to produce enough of the enzyme.
b. Lipase Test: This test measures the amount of lipase, an enzyme made by the pancreas, in the blood. Low levels of lipase indicate that the pancreas is not able to produce enough of the enzyme.
c. Imaging Tests: Imaging tests such as CT scans and MRI scans can be used to look for signs of damage to the pancreas.
2. Endoscopic Tests
Endoscopic tests are used to evaluate the structure of the pancreas and look for signs of infection or inflammation. Common endoscopic tests used to diagnose chronic pancreatitis include:
a. Endoscopic Retrograde Cholangiopancreatography (ERCP): This test is used to look for blockages or narrowing in the ducts of the pancreas.
b. Endoscopic Ultrasound (EUS): This test is used to look for signs of inflammation or infection in the pancreas and surrounding tissues.
3. Blood Tests
Blood tests are used to measure levels of certain hormones and enzymes in the blood that can indicate pancreatic disease. Common blood tests used to diagnose chronic pancreatitis include:
a. Amylase and Lipase Tests: These tests measure the levels of amylase and lipase enzymes in the blood. High levels of these enzymes can indicate pancreatic disease.
b. Trypsin Test: This test measures the level of trypsin, an enzyme made by the pancreas, in the blood. High levels of trypsin can indicate pancreatic disease.
c. Fasting Glucose Test: This test measures the amount of glucose, a sugar, in the blood after a period of fasting. High levels of glucose can indicate pancreatic disease.
