The best possible health through screening

Our Mission

  • Ensure every newborn receives the highest quality screening and care for serious diseases.
  • Continuously develop and improve the integrated system of screening for the population we serve*.
  • Be global leaders in screening through research, development, education, and innovation.


*The integrated screening system includes:

  1. mechanisms for educating and enrolling the target population, including the consideration of consent,
  2. the screening test itself and its interpretative process,
  3. mechanisms for retrieving individuals identified to be at risk, conducting diagnostic evaluations, and initiating treatments or interventions as indicated,
  4. data management and performance measurement infrastructure to ensure high performance of all components, and
  5. a robust policy setting and governance structure.
