A deficient plasma C-Peptide response to a defined protein/carbohydrate meal is seen in diabetes mellitus. For most clinical purposes the 24-hr urinary C-Peptide excretion gives an adequate and more convenient index of endogenous pancreatic function. Excessive urinary C-Peptide excretion is seen in insulinoma. Deficient C-Peptide excretion is seen in diabetes mellitus and in hypoglycaemia due to the administration of exogenous insulin.
