This test measures the level of C-peptide in your blood or urine. C-peptide is a substance made in the pancreas, along with insulin. Insulin is a hormone that controls the body's glucose (blood sugar) levels. Glucose is your body's main source of energy. If your body doesn't make the right amount of insulin, it may be a sign of diabetes.
In the beta cells of the islet of Langerhans of the pancreas, the chains of pros=insulin are separated during the conversion of proinsulin to insulin and C-peptide. C-peptide is released into the portal vein in nearly equal amounts. C-peptide (connecting peptide), a 31-amino-acid polypeptide, represents the midportion of the proinsulin molecule. Proinsulin resembles a hairpin structure, with an N-terminal and C-terminal, which correspond to the A and B chains of the mature insulin molecule, oriented parallel to each other and linked by disulfide bonds. Test results are given in nanograms per milliliter (ng/mL). Normal results are within the range of 0.5 to 2.7 ng/mL, but can vary depending upon the lab that is used for testing. A high level of C-peptide could mean a number of conditions.

2,3 In the process of biosynthesis of insulin, the C-peptide is formed as a byproduct together with insulin by the proteolytic cleavage of the precursor molecule proinsulin, stored in secretory granules in the Golgi complex of the pancreatic β-cells.

C-Peptide - C-Peptide is useful in the evaluation of pancreatic beta cell function (e.g., helping distinguish type 1 from type 2 diabetes mellitus, or monitoring patients who have received islet cell or pancreatic transplants) and for determining the source of insulin in patients with hyperinsulinemic hypoglycemia (e.g., distinguishing insulin-secreting tumors from exogenous insulin administration). C-peptide is a single chain 31-amino acid (AA 33-63) connecting (C) polypeptide with a molecular weight of approximately 3021 daltons. 2,3 In the process of biosynthesis of insulin, the C-peptide is formed as a byproduct together with insulin by the proteolytic cleavage of the precursor molecule proinsulin, stored in secretory granules in the Golgi complex of the pancreatic β-cells. C-peptide is a protein that connects the beta and alpha chains of proinsulin. In the beta cells of the islet of Langerhans of the pancreas, the chains of pros=insulin are separated during the conversion of proinsulin to insulin and C-peptide. C-peptide is released into the portal vein in nearly equal amounts.

A C-peptide test may be useful when evaluating hypoglycemia, metabolic syndrome, insulin resistance, hypertension and cholesterol imbalances.

The Role of C-Peptide If providers suspect a patient is taking exogenous insulin, whether cross-reactivity is noted or not, pay particular attention to the insulin/C-peptide ratio. Insulin and C-peptide are co-products of proinsulin, and therefore released in the bloodstream at equimolar amounts, with insulin metabolized in the liver, and C-peptide excreted by the kidneys.
