Plasma C peptide in hyperinsulinaemic hypoglycaemia.
We describe two children with hypoglycaemia due to pancreatic beta cell hyperactivity. Both had low serum insulin but raised plasma C peptide concentrations when hypoglycaemic. Measurement of C peptide is valuable in the diagnosis of hyperinsulinaemic hypoglycaemia in children.
