Understanding Lab Tests for Autoimmune Pancreatitis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Autoimmune pancreatitis (AIP) is a rare form of chronic pancreatitis where the body's immune system mistakenly attacks the pancreas, causing inflammation and potential organ dysfunction. This condition can be challenging to diagnose, but specific blood tests can help identify the autoimmune nature of the pancreatic inflammation.
Recommended Test
Pancreatic Exocrine Cell Antibody
This specialized blood test detects antibodies that specifically target pancreatic exocrine cells. In autoimmune pancreatitis, the immune system produces these antibodies as it attacks pancreatic tissue, causing chronic inflammation. The presence of these antibodies in the bloodstream serves as a key indicator of autoimmune pancreatitis and helps healthcare providers distinguish this condition from other pancreatic disorders.

Diagnosing Autoimmune Pancreatitis
Unlike typical pancreatitis caused by gallstones or alcohol, autoimmune pancreatitis involves the immune system producing antibodies that target pancreatic tissue. Blood testing plays a crucial role in detecting these specific antibodies, which can confirm the autoimmune component of the condition and help distinguish it from other forms of pancreatitis or pancreatic cancer.
Understanding Your Results
A positive result for pancreatic exocrine cell antibodies, combined with clinical symptoms and imaging findings, can support a diagnosis of autoimmune pancreatitis. This information is essential for guiding appropriate treatment, which often includes immunosuppressive therapy rather than the standard treatments used for other forms of pancreatitis.
