Summary
Newborn screening has evolved from a single-disorder test to a comprehensive public health system over 40 years. Understanding its history is crucial for addressing current challenges in predictive medicine.
Area of Science:
- Public Health
- Genetics
- Pediatrics
Background:
- Newborn screening has a 40-year history.
- Initial screening focused on single disorders like phenylketonuria (PKU).
- It has evolved into a complex public health system.
Purpose of the Study:
- To review the history of newborn screening.
- To understand the evolution of newborn screening practices.
- To provide context for current challenges in the field.
Main Methods:
- Historical review of newborn screening.
- Analysis of the conceptual evolution of screening programs.
- Examination of the components of modern newborn screening systems.
Main Results:
- Newborn screening has transformed significantly over four decades.
- The scope has expanded from single-disorder testing to a multi-faceted public health approach.
- Current screening encompasses education, diagnostics, treatment, and evaluation.
Conclusions:
- Newborn screening is a model for predictive medicine.
- The program faces critical challenges impacting its future.
- Historical context is essential for navigating these challenges and ensuring continued viability.
