gamma-Glutamyltransferase in the newborn.
gamma-Glutamyltransferase activity was measured serially in newborn infants. Median activity was 94 units/l, with the 95th centile at 243 units/l. It was unrelated to gestation. Significant increases occurred after treatment with phenobarbitone and with the introduction of oral feeding after parenteral nutrition. It was a poor indicator of total parenteral nutrition (TPN) liver damage.
