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

Not Applicable

Completed

• Conditions: Jaundice, Neonatal

• Registration Number: NCT05650463
• Lead Sponsor: Picterus AS

Brief Summary

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

Detailed Description

To adjust Picterus JP to work in newborns with more pigmented skin, the investigators will collect a data set at Sachsska barnsjukhuset Södersjukhuset, Stockholm Sweden from 150 newborns with dark skins using Picterus JP, TcB, skin measurements from a spectrometer, visual assessment, and total serum bilirubin (TSB) levels. As a control, newborns with Neomar scale 1-3 will be included.
