Newborn screening detects genetic disorders early, but effective treatments are limited. Improving pre- and post-analytical phases and considering prenatal screening are crucial for better outcomes.

Area of Science:

  • Medical Genetics
  • Public Health
  • Neonatal Care

Background:

  • Newborn screening facilitates early detection of genetic disorders to enable timely intervention and prevent severe health consequences.
  • While screening programs exist globally, effective therapies are available for only a fraction of the thousands of known genetic conditions.
  • Phenylketonuria (PKU) was the first disorder targeted by newborn screening, which is now implemented in 26 countries for various diseases.

Purpose of the Study:

  • To evaluate the current state and challenges of newborn screening programs.
  • To identify critical areas for improvement in the screening process.
  • To explore the potential benefits of prenatal genetic screening and diagnostics.

Main Methods:

  • Review of existing newborn screening protocols and their implementation status.
Keywords:

  • Analysis of error rates in different phases of the screening process (pre-analytical, analytical, post-analytical).
  • Discussion of challenges including quality assessment, technical competence, and ethical considerations.

    • Main Results:

    • Significant challenges in newborn screening implementation include quality assurance, professional competence, and ethical concerns.
    • The majority of errors in the screening process occur during the pre- and post-analytical phases.
    • Current screening occurs post-birth, potentially delaying crucial interventions.

    Conclusions:

    • Enhancing pre- and post-analytical processes is vital for improving the accuracy and efficiency of newborn screening.
    • Ethical considerations and technical competence require ongoing attention in program development.
    • Shifting genetic screening and diagnostics to earlier in pregnancy could offer greater benefits for fetal health.
