Risk Factors for the Development of Delayed TSH Elevation in Neonatal Intensive Care Unit Newborns

摘要

AbstractContextDelayed thyrotropin (TSH) elevation (dTSH) is defined as elevated TSH at the second neonatal screening (after normal TSH levels at the initial screening) in premature, low-birth-weight, and ill newborns, mostly in the neonatal intensive care unit (NICU) setting. The pathogenesis of dTSH is elusive.
