A C-peptide blood test is a test used to measure the level of C-peptide in a person's blood. C-peptide is a protein produced by the pancreas along with insulin. The test is used to diagnose and monitor conditions that affect insulin production, such as diabetes. It is also used to monitor the effectiveness of insulin replacement therapy in people with diabetes. The test is performed on a small sample of blood taken from a vein in the arm.
