Order C-Peptide, Blood TestThe C-Peptide, Blood Test measures the amount of C-peptide circulating in the bloodstream. C-peptide is a short chain of amino acids released when the pancreas converts proinsulin into insulin, making it a useful indirect marker of the body's own insulin production. Because it is cleared more slowly than insulin, it can offer a steadier view of pancreatic beta-cell activity.
About C-Peptide, Blood Test in Phoenix
This test is typically ordered when a clinician needs to distinguish between endogenous insulin production and insulin that has been administered externally.
When the pancreas produces insulin, it also releases C-peptide in roughly equal amounts. Exogenous insulin preparations do not contain C-peptide, so a low C-peptide level alongside high insulin can suggest that insulin is coming from outside the body rather than from the pancreas.
C-peptide testing is also used to evaluate beta-cell function in people with diabetes or hypoglycemia of unclear cause. It can help characterize whether a person still produces meaningful amounts of insulin, which has implications for how a case is managed.
The test requires a blood sample, usually collected from a vein in the arm. Results are generally reported within a few business days. Preparation instructions vary by laboratory, so following the collecting lab's guidance is important for accurate interpretation.
