Description

The C-Peptide blood test looks at how the body makes insulin and used to diagnose blood sugar disorders. Measuring C-Peptide can show whether you have type 1 or type 2 diabetes. In type 1 diabetes your body doesn't make any insulin. In type 2 diabetes, either your body doesn't make enough insulin, or your cells can't use it normally. The C-Peptide blood test may also be done to find the cause of low blod sugar levels.
