ABSTRACT

Neonatal jaundice remains a preventable cause of neurological damage in low- and middle-income countries, where limitations in infrastructure and staffing make timely screening difficult. Mobile technologies, such as the Picterus Jaundice Pro (JP) app, offer a promising alternative by enabling bilirubin estimation from digital images using algorithms and calibration cards. In this viewpoint, we explore the feasibility, clinical validation, and barriers to adopting this tool in resource-limited settings, particularly in Latin America. The Mexican experience is presented as a reference for the gradual integration of mHealth technologies into public systems, highlighting both opportunities and regulatory, operational, and cultural challenges. Available evidence supports its utility; however, scaling will depend on political will, sustained financing, and clear regulatory frameworks. Picterus JP may represent a strategic step toward equity in neonatal health.
