Order C-Peptide, Blood TestThe C-peptide blood test measures a byproduct released when the pancreas produces insulin. Because C-peptide is cleared from the bloodstream more slowly than insulin, it offers a stable view of how much insulin the body is making endogenously. Clinicians use this marker to distinguish between conditions that involve insulin production and those that do not, and to monitor pancreatic function over time.
About C-Peptide, Blood Test in Urbana
C-peptide is a short chain of amino acids that connects the two parts of proinsulin, the precursor molecule to insulin.
When the pancreas processes proinsulin into active insulin, it splits off C-peptide in equal amounts. This means C-peptide levels generally mirror the amount of insulin the pancreas is producing on its own, independent of any insulin that may have been taken as medication.
Because exogenous insulin preparations do not contain C-peptide, measuring this marker helps separate endogenous insulin production from injected insulin. This distinction is useful when evaluating hypoglycemia, suspected insulin resistance, or the progression of diabetes.
The test requires a blood sample, typically drawn from a vein in the arm. Results are usually reported in nanograms per milliliter or nanomoles per liter, and reference ranges vary by laboratory, so values are interpreted alongside the clinical picture rather than in isolation.
