What is the c-peptide assay test in diabetic patient?

In brief: Endogenous insulin

The c-peptide assay is an indirect way of looking at how much Insulin a person's pancreas is producing.
If you measure a type 1 diabetic's c-peptide level, it should be negligible as their pancreas has lost the ability to produce insulin. In a type 2 diabetic, c-peptide levels are frequently elevated due to Insulin resistance (their pancreas must make extra Insulin to overcome their resistance).
