How to get a precise diagnosis of your diabetes type? the c-peptide test show the insulin production but how to test your insulin resistance(can a diabetic make the insulin resistance test??

If you are an adult and C-peptide level confirms the insulin production, type 2 diabetes is confirmed. The insulin resistance can be from insulin antibodies (abs) or because the insulin receptors on the cell surface are less sensitive to insulin. The former can be detected by blood test but not the latter. Insulin abs do not have clinical significance but the fx of insulin receptors are important.
