Does umbilical cord blood glucose extraction discriminate the risk of early neonatal hypoglycaemia in at-risk newborns?

Umbilical cord blood glucose extraction discriminates the risk of early hypoglycaemia at 1 or 4 h of age. However, the clinical utility of this test is limited due to the low sensitivity and specificity. Its predictive value may be greater in specific subsets of at-risk newborns and warrants further investigation.
