Order C-Peptide, Blood TestThe C-peptide blood test measures a fragment of proinsulin that is released in equimolar amounts with insulin. Because C-peptide is not extracted by the liver to the same degree as insulin, it offers a stable index of endogenous pancreatic beta-cell secretion. The test is used to distinguish between endogenous insulin production and exogenous insulin administration, and to evaluate the cause of hypoglycemia.
About C-Peptide, Blood Test in Queens
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 in the pancreatic beta cell, insulin and C-peptide are secreted together into the bloodstream.
Measurement of C-peptide is most often ordered when a clinician needs to assess whether the pancreas is still producing insulin. In a person receiving exogenous insulin, a low C-peptide result supports the presence of diminished endogenous secretion, whereas a normal or elevated result points to preserved beta-cell function.
The test is also used in the evaluation of spontaneous hypoglycemia. A high C-peptide level during a low blood glucose episode suggests that the body is producing too much insulin on its own, while a low level suggests that the hypoglycemia is not driven by endogenous insulin release.
C-peptide is cleared more slowly than insulin and is not substantially degraded by the liver, so its concentration in blood is less variable. Results are interpreted alongside glucose, insulin, and sometimes proinsulin or sulfonylurea screening, depending on the clinical question.
