Evaluation of a Smartphone-based Screening Tool (Picterus Jaundice Pro) for Neonatal Jaundice in Dark Skin Newborns

A cross-sectional study at the Södersjukehuset facility (Stockholm, Sweden) collect data of newborns from a population with Neomar scale type 4 to adjust the algorithm of Picterus JP

As a control, newborns with Neomar scale 1-3 will be included.
