Implication

Validation study demonstrates accurate noninvasive transcutaneous bilirubin estimation in neonates, indicating potential to reduce invasive blood draws and hospital stay.

Key Points

To assess the clinical accuracy and utility of a handheld skin-reflectance device (Chromatics Colormate III) for noninvasive serum bilirubin estimation in newborns.
Monitored 2,441 term and premature neonates across two hospitals using transcutaneous reflectance measurements, with 900 infants receiving concurrent laboratory serum bilirubin tests.
Evaluated a subgroup of 61 infants undergoing phototherapy across 284 paired comparisons and determined device reproducibility using standardized color tiles and repeated testing over 30 minutes.
Transcutaneous measurements correlated strongly with laboratory serum bilirubin across concentrations from 3.22 to 338.1 micromol/L (0.2 to 21 mg/dL), achieving r = 0.956, with 95% of readings falling within 32.2 micromol/L (2.0 mg/dL).
Measurement accuracy was unaffected by race, birth weight, or phototherapy, demonstrating a repeated-measures coefficient of variation of 3.1% around a mean estimate of 135.32 micromol/L (8.4 mg/dL).
