Reference ranges for thyroid volumes in newborns of different gestational ages have not been previously determined. We assessed thyroid volume within the first week of life in a sufficient number of neonates of different gestational ages to establish normal ranges for babies born in Turkey.

blood thyroglobulin concentration 2–54 ng/ml.
We included neonates whose mothers did …
