Order C-Peptide, Blood TestC-peptide is a short chain of amino acids released when the pancreas converts proinsulin into insulin. Because it is secreted in equimolar amounts with insulin but clears more slowly, a blood measurement offers a stable view of endogenous insulin production. The test is used to evaluate how well the beta cells are functioning and to distinguish between sources of insulin in the circulation.
About C-Peptide, Blood Test in Davis
C-peptide testing provides a direct window into pancreatic beta-cell activity.
When the pancreas produces insulin, it first creates proinsulin and then splits it into insulin and C-peptide. The two are released together, but C-peptide has a longer half-life, so blood levels remain measurable even when insulin itself fluctuates or is cleared quickly. This makes C-peptide a useful marker of how much insulin the body is making on its own.
The test is commonly ordered when a clinician needs to evaluate hypoglycemia, assess beta-cell reserve, or determine whether insulin in the bloodstream comes from the pancreas or from an external source. Because many insulin assays cannot distinguish between endogenous and injected insulin, C-peptide can help clarify that picture.
Results are interpreted alongside glucose levels, clinical history, and other laboratory findings. A low C-peptide value may suggest reduced endogenous insulin production, while an elevated value may indicate increased beta-cell output. Reference ranges vary by laboratory, so results should always be reviewed in the context of the individual patient and the reporting lab's stated intervals.
