Pancreatic Endocrine Function Screening (Serum)

What This Test Measures

Your blood sample will be analyzed for several hormones produced by the pancreas’s endocrine cells. Commonly included tests may measure insulin, C-peptide, glucagon, somatostatin, pancreatic polypeptide, and other regulatory peptides. These hormones help control blood sugar, digestion, and growth processes.

Why It’s Ordered

Your healthcare provider may recommend this test if you have symptoms like unexplained weight changes, persistent fatigue, abnormal blood sugar levels, or a family history of pancreatic disorders. It can also be part of an evaluation for conditions like diabetes, pancreatic tumors, or hormonal imbalances.

Common Conditions Evaluated

This screening can help diagnose or monitor conditions such as insulinoma (a tumor producing excess insulin), Zollinger-Ellison syndrome (excess stomach acid), or other endocrine pancreatic disorders. It may also assist in assessing metabolic or digestive issues linked to pancreatic hormone dysfunction.

Sample Collection and Preparation

A blood sample will be drawn from a vein, typically in your arm. You may be asked to fast for a few hours before the test, depending on the specific hormones being measured. Store your sample according to lab instructions to ensure accurate results.
