BiliCalc is a neonatal bilirubin calculator and clinical reference for healthcare professionals caring for newborn infants born at 35 or more weeks of gestation. Calculations are based on the 2022 American Academy of Pediatrics (AAP) Clinical Practice Guideline for the management of hyperbilirubinemia in newborn infants 35 or more weeks of gestation. Enter the infant's postnatal age, gestational age at birth, bilirubin value, measurement type, applicable neurotoxicity risk factors, and phototherapy status to view: • Patient-specific phototherapy, escalation-of-care, and exchange-transfusion thresholds • A graph displaying the bilirubin value and applicable treatment thresholds • Guideline-based treatment recommendations • Post-discharge follow-up guidance, when applicable No internet connection is required for calculations. BiliCalc performs calculations locally on the device and can be used without Wi-Fi or cellular data. BiliCalc is designed for quick clinical reference and does not measure bilirubin. Bilirubin values and other clinical information must be obtained independently and entered by the healthcare professional. Clinical references and links to source material are available within the app. BiliCalc is intended to support, not replace, professional clinical judgment. It is independently developed and is not affiliated with, sponsored by, or endorsed by the American Academy of Pediatrics.

This app helps healthcare professionals determine the need for phototherapy or exchange therapy in newborns based on their age, bilirubin levels, and risk factors. It utilizes the latest American Academy of Pediatrics guidelines and displays results on interactive nomograms. The app also tracks infant data and provides links to relevant research.

Use Quick Check to compare a total serum bilirubin reading with American Academy of Pediatrics (AAP) 2022 phototherapy, escalation-of-care, and exchange-transfusion thresholds. Enter age in hours, gestation, and additional neurotoxicity risk factors. View the result and threshold charts in mg/dL or µmol/L. Track infants locally to review reading history, plot trends, and calculate the rate of rise. A date-and-time calculator helps determine age at measurement. Share a text result summary using the device's share sheet. The 2022 guideline is selected by default. An optional legacy AAP 2004 pathway is available in Settings, with its supported chart range clearly identified. Reference material and links to source guidelines are included.
