Beginning in the 1960s, mandatory newborn screening (NBS) of essentially all infants has been a major public health success story. NBS is not just a blood test, rather, it is a complex, integrated system that begins with timely testing, scrupulous follow up of patients, tracking of outcomes, quality improvement of all aspects of the process, and education of providers, staff, and parents. In the past, expansion of NBS programs has been driven by new testing technology, but now is increasingly driven by the development of novel therapeutics and political advocacy. Each state determines how the NBS system will be structured in that state, but there is increasing oversight and support for harmonization at a federal level. Several recent initiatives, together with the increased number of conditions screened and the concomitant increase in burdensome false-positive tests, are creating new scrutiny of NBS systems, and potentially pose an existential risk to the public acceptance of mandatory NBS. The history, current state and challenges for NBS are explored in this issue, with some suggestions as to how to address them.
