the mean amniotic fluid concentrations of proinsulin ( 0.07 nmole/l ) , insulin ( 0.08 nmole/l ) , c-peptide ( 1.17 nmoles/l ) , and glucose ( 2.09 mmoles/l ) were markedly elevated ( p less than 0.001 ) in diabetic patients , as compared to nondiabetic control patients , thus suggesting exaggerated fetal beta cell function .
