Understanding Lab Tests for Acute Pancreatitis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Acute pancreatitis is a sudden inflammation of the pancreas that can cause severe abdominal pain and serious complications. Blood tests play a crucial role in diagnosing this condition by measuring specific enzymes and markers that are released when pancreatic cells are damaged.
Top Recommended Test
Lipase, Serum
This is the primary diagnostic test for acute pancreatitis. Lipase is an enzyme produced by the pancreas, and when pancreatic cells are damaged due to inflammation, lipase leaks into the bloodstream causing significantly elevated blood levels. This test is highly specific for pancreatic injury.

How Blood Tests Diagnose Acute Pancreatitis
When the pancreas becomes inflamed, damaged cells release enzymes and other substances into the bloodstream. These elevated levels can be detected through blood tests, providing healthcare providers with essential information to confirm the diagnosis and assess the severity of the condition.
Other Relevant Tests
Amylase, Serum
Amylase levels typically rise 4 to 6 hours after the onset of acute pancreatitis and remain elevated for several days. High levels of amylase in the blood serve as an important indicator of pancreatic inflammation, though this enzyme can also be elevated in other conditions.

Lactic Acid Dehydrogenase (LD) (LDH)
LDH levels become elevated in acute pancreatitis as this enzyme is released from damaged pancreatic cells into the bloodstream. This test helps assess the extent of cellular damage and can indicate the severity of the condition.

Aspartate Aminotransferase (AST/SGOT)
AST levels can be elevated in acute pancreatitis due to the sudden inflammation of the pancreas. This test provides additional information about the body's response to pancreatic injury and helps healthcare providers assess overall organ function.

Understanding Your Test Results
Elevated levels of these enzymes, particularly lipase and amylase, are key indicators of acute pancreatitis. Your healthcare provider will interpret these results alongside your symptoms and medical history to confirm the diagnosis and determine the appropriate treatment plan.
