Validity of transcutaneous bilirubin measurements during and after phototherapy in term and late preterm infants.

Unlabelled: The purpose of the study was to investigate correlation and concordance between total serum bilirubin (TSB) and transcutaneous bilirubin measured at covered (TcBC) and uncovered (TcBU) skin during and after discontinuation of phototherapy. A cross-sectional study included ≥ 34 weeks gestation infants requiring phototherapy for neonatal hyperbilirubinemia. In-house, photo-opaque patches were placed on infants' sternums before phototherapy initiation.
