C-peptide can be used to monitor insulin production in the body, blood sugar disorders, and the activity of tumors that secrete insulin.
It can also help determine if you have type 1 or type 2 diabetes (Type 1 = your body doesn’t make insulin. Type 2 = either your body doesn’t make enough insulin or your cells ignore it). If you have diabetes, the C-peptide test can show how well your treatment is working.
