Abstract Aim Neonatal jaundice is an important cause of morbidity and mortality, identifying the condition remains a challenge. This study evaluated novel method estimating bilirubin levels from colour‐calibrated smartphone images. Methods A cross‐sectional prospective was undertaken at two hospitals in Norway February 2017 to March 2019, with standardised illumination one hospital non‐standardised other hospital. Healthy term‐born infants normal birthweight were recruited up 15 days age. The main outcome measures estimates digital images, plus total serum (TSB) transcutaneous (TcB). Results Bilirubin performed for 302 newborn infants, 76 had severe jaundice. correlation between TSB measured by Pearson's r .84 whole sample. image TcB 0.81. There no significant differences hospitals. Sensitivity 100%, specificity 69% more than 250 µmol/L. Conclusion smartphone‐based tool that estimated images identified high sensitivity could provide screening neonatal
