What Hormones Are Tested?

This screening typically includes measurements for several pancreatic hormones, such as insulin, glucagon, somatostatin, and pancreatic polypeptide. These hormones regulate blood sugar, digestion, and growth processes. The exact hormones tested may vary based on clinical needs.

Why Might You Need This Test?

Your doctor may order this test if you have symptoms like unexplained weight changes, diabetes, digestive issues, or signs of hormonal imbalances. It’s also used in diagnosing conditions like pancreatic tumors, Zollinger-Ellison syndrome, or other endocrine disorders.

Common Conditions Monitored

This test can help identify or track conditions such as insulinoma (a tumor producing excess insulin), glucagonoma (a tumor producing excess glucagon), or other pancreatic endocrine neoplasms. It may also be used in patients with suspected pancreatic dysfunction.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The sample is collected in a tube that separates serum or plasma from blood cells. This liquid portion is then sent to a lab for testing. You may be asked to fast before the test if instructed by your doctor.

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long does it take to get results?
Results are typically available within 1 to 3 business days, depending on your lab’s processing time. Your doctor will discuss the results with you during your follow-up visit.
What do abnormal results mean?
Abnormal results may indicate an overproduction or underproduction of pancreatic hormones, which could signal conditions like tumors, diabetes, or other endocrine disorders. Your doctor will interpret the results in the context of your symptoms and medical history.
Can I eat or drink before this test?
Follow your doctor’s instructions, but generally, you may drink clear fluids (like water) but avoid food for 8 to 12 hours before the test if fasting is required.
