The C-Peptide test measures the level of C-peptide in the blood, a substance released when the body produces insulin. Because C-peptide and insulin are produced in equal amounts, this test helps evaluate how much insulin the pancreas is making.
This test is commonly used to assess insulin production, distinguish between type 1 and type 2 diabetes, evaluate unexplained low blood sugar, and monitor pancreatic function. It may also be helpful in determining whether insulin in the body is produced naturally or comes from injected insulin.
