What does this test check?
When the pancreas makes insulin, it releases C-peptide in equal amounts. Insulin injections do not contain C-peptide, so this test shows how much insulin your own body is producing, even if you already take insulin.
Diabetologists use it to help tell type 1 from type 2 diabetes, to check whether tablets may still work, and to plan treatment when diabetes is hard to control. Post-meal and random C-peptide can also be done.
