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 endogenous insulin production. Because it is cleared more slowly than insulin and is not present in most exogenous insulin preparations, C-peptide can help distinguish insulin made by the body from insulin administered as a medication.
About C-Peptide, Blood Test in Long Beach
What the C-Peptide, Blood Test evaluates
C-peptide is produced in the pancreatic beta cells as part of the normal processing of proinsulin. When proinsulin is cleaved, insulin and C-peptide are released in equimolar amounts into the portal circulation. A blood test for C-peptide therefore reflects how much insulin the pancreas is secreting, rather than how much insulin is present from an external source.
The test is typically used to assess beta-cell function in the context of hypoglycemia, diabetes, or suspected insulin misuse. In a spontaneous hypoglycemic episode, a low C-peptide level alongside low blood glucose points toward an exogenous source of insulin, while an elevated C-peptide level suggests the body is producing excess insulin on its own. It can also be ordered when evaluating residual beta-cell activity in diabetes or after pancreatic surgery.
Sample collection involves a standard blood draw, usually from a vein in the arm. The specimen is processed in the laboratory, and results are reported as a concentration, often in nanograms per milliliter or picomoles per liter. Reference ranges vary by laboratory and by the clinical context, so results should be interpreted by a qualified healthcare professional alongside glucose, insulin, and other relevant findings.
