C-peptide Blood Test - More Information

The C-peptide test measures blood level of C-peptide, a molecule that consists of amino acids. The C-peptide test level is sometimes helpful to measure when used in conjunction with the blood Insulin test level as C-peptide and insulin are bound together when made by the pancreas.

Although C-peptide levels are related to insulin levels, C-peptide as measured by the C-peptide blood test typically does not affect the blood glucose (as measured by the blood Glucose test) or Hemoglobin A1c levels. However, C-peptide can be useful in determining if excessive medication use or tumors are causing low blood sugar levels. C-peptide levels are useful in determining if someone has Type I diabetes as the C-peptide levels are typically low in those instances.

Overall, along with diabetes markers measured in the Diabetes Management Panel, C-peptide levels are being used more regularly in assessing overall diabetic control.
