I present a free open source webapp for calculating neonatal jaundice treatment thresholds (bilirubin ‘nomograms’) based on UK National Institute for Health and Care Excellence (NICE) guidelines. The calculator can be accessed at https://yingtongli.me/bili/.

Please note that the calculator is based on the 2010 NICE treatment thresholds, which differ to alternative treatment threshold graphs such as those in the 2022 American Academy of Paediatrics guidelines or Queensland Health guidelines.
