C-Peptide

Unveil insulin production insights with C-Peptide, aiding precise diabetes care. C-Peptide is a connecting-protein related to insulin, and its levels can be useful in predicting susceptibility to the development of type II diabetes. It can also be measured to estimate a patient's capacity for insulin secretion or in the evaluation of insulin sensitivity. The adequacy of pancreatic insulin synthesis is frequently assessed via the determination of C-peptide. Fasting-insulin is also measured to assess insulin resistance. C-peptide can also be used in the evaluation of hypoglycemia. Patients with insulin-secreting neoplasms (cancers) have high levels of both C-peptide and endogenous insulin; in contrast, patients with factitious hypoglycemia will have low C-peptide levels in the presence of elevated (exogenous) serum insulin. C-peptide is also useful in evaluating residual beta-cell function in insulin-dependent diabetics, many of whom have antibodies that interfere with insulin assays.
