C Peptide

C Peptide


The C-Peptide test measures the level of C-peptide in your blood, a substance released when your body produces insulin. By checking C-peptide levels, doctors can determine whether your body is making enough insulin or if insulin production is reduced. This test is often used to distinguish between Type 1 and Type 2 diabetes, monitor insulin therapy, or investigate low blood sugar episodes. It can also help assess pancreatic function in certain medical conditions.
