C Peptide is a molecule made in the pancreas along with insulin. Insulin is a hormone that regulates blood glucose levels, as glucose is the main source of energy. If insulin levels are low or absent, the body glucose consumption cannot be regulated and this leads to diabetes. During diabetes treatment, C peptide test is performed to differenciate the endogene insülin (produced by pancreatic cells) and the exogenous insulin given by injection. C Peptide test, gives the amount of insulin produced by the body. In Type 1 diabetes, the body makes almost no insulin parallel to C Peptide production. In type 2 diabetes, the body makes adequate insülin, but that insulin cannot lead glucose into the cells to be used for energy, because of the resistence of the cell membrane to insulin. Therefore C Peptide levels will increase in blood.
Interpretation: Low C peptide levels indicate Type 1 Diabetes High C Peptide levels indicate Type 2 Diabetes
