C-Peptide test

C-Peptide test measures the amount of C-Peptide in the blood or urine. It is a chemical produced by the pancrease in almost the same proportion as insulin. Hence, it can be used as an indicator of the amount of insulin produced in the body. This test is mainly used to distinguish between Type I and Type II diabetes. Type I diabetes is characterized by negligible amounts of insulin and C-peptide. However, in type II diabetes, insulin and C-Peptide levels are beyond normal.This test is also recommended by doctors to check the treatment of diabetes.
