Order C-Peptide, Blood TestThe C-peptide blood test measures a fragment of proinsulin that is released in equal amounts to insulin. Because C-peptide is not extracted by the liver to the same degree as insulin, it offers a stable indicator of how much insulin the pancreas is producing. This makes it useful when the goal is to assess endogenous insulin secretion rather than circulating insulin levels alone.
About C-Peptide, Blood Test in Orange
C-peptide is a short chain of amino acids that connects the A and B chains of insulin within the proinsulin molecule. When proinsulin is cleaved, insulin and C-peptide enter the bloodstream in a 1:1 ratio.
Laboratories measure C-peptide in blood, most often by immunoassay. Because the peptide is cleared more slowly than insulin, concentrations remain relatively steady and can be interpreted alongside glucose and insulin results.
The test is typically ordered when a clinician needs to distinguish between endogenous insulin production and externally administered insulin. It can also be used to evaluate the function of pancreatic beta cells in conditions that affect insulin secretion.
Results are usually reported in nanograms per milliliter or picomoles per liter. Reference intervals vary by laboratory and by the assay method used, so values should be interpreted against the range provided on the report.
