Understanding Lab Tests for Pancreatic Beta Cell Hyperplasia
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Pancreatic beta cell hyperplasia is a rare condition characterized by an abnormal increase in the number of insulin-producing beta cells in the pancreas. This condition can lead to excessive insulin production, potentially causing hypoglycemia (low blood sugar). While imaging studies are typically used for definitive diagnosis, blood testing plays a crucial role in evaluating insulin production and metabolic function.
Recommended Test
C-Peptide, Serum
C-peptide is released in equal amounts with insulin from pancreatic beta cells. In pancreatic beta cell hyperplasia, the increased number of insulin-producing cells results in elevated C-peptide levels. This test provides a reliable measure of endogenous insulin production and helps assess the functional impact of increased beta cell mass.

The Role of Blood Testing in Beta Cell Hyperplasia
Blood tests cannot directly diagnose pancreatic beta cell hyperplasia itself, but they are fundamental for assessing the functional consequences of increased beta cell mass. These tests help measure insulin production capacity and evaluate the metabolic impact of the condition, providing essential information for diagnosis and monitoring.
Understanding C-Peptide Testing
C-peptide testing is particularly valuable because it reflects the body's natural insulin production. Unlike insulin itself, C-peptide is not affected by external insulin administration and has a longer half-life, making it an excellent marker for evaluating pancreatic beta cell function. Elevated levels may indicate hyperactivity of beta cells, which can occur in conditions like beta cell hyperplasia.
