C-peptide test

C-peptide test

a blood test used to evaluate levels of C-peptide, which correlate with insulin levels in the blood.

It is used to evaluate patients with suspected insulinoma, renal failure, pancreas transplant, factitious hypoglycemia, radical pancreatectomy, and diabetes mellitus.
