C-Peptide Analysis in Diabetes

C-peptide is a crucial biomarker for assessing insulin secretion and pancreatic beta-cell function in diabetes. It is produced in equal amounts to insulin but is not used by the body, making it an ideal indicator of endogenous insulin production. In Type 1 diabetes, low or undetectable C-peptide levels indicate insufficient insulin production due to autoimmune destruction of beta cells. Conversely, in Type 2 diabetes, elevated C-peptide levels may reflect insulin resistance, where the body compensates by producing more insulin. Regular C-peptide analysis can help clinicians differentiate between diabetes types, monitor disease progression, and evaluate the effectiveness of therapeutic interventions. Understanding C-peptide dynamics can also inform personalized treatment strategies, enhancing patient outcomes.
