Normal C-peptide levels range from 0.5 to 2.0 nanograms per milliliter. A value higher than 2.0 means you may have type 2 diabetes. How do C-peptide levels differentiate between type 1 and 2 diabetes?

Dear Dr. Roach: I was recently diagnosed with Type 1 diabetes at the age of 62 ... U/mL and was confirmed twice by the lab. My C-peptide level is below 1 ng/mL. My blood sugar level was 542 ...

Whether improved glucose control with hybrid closed-loop therapy can preserve C-peptide secretion as compared with standard insulin therapy in persons with new-onset type 1 diabetes is unclear.

Considering the rate of misdiagnosis, it may be prudent to rule out type 1 diabetes regardless of your weight or age by testing your c-peptide level or checking for autoantibodies. The Treatment ...
