Newborn screening is comprised of three different parts:
- Dried blood spot screening (identifies heritable disorders)
- Hearing screening
- Critical congenital heart disease screening.
Public health laboratories conduct screenings on dried blood spots.
Newborn screening programs are state- or territory-based, so variations exist between programs in the number of disorders screened and the number of routine specimens collected from each newborn.
While states determine which disorders to screen, federal guidance is provided by the US Department of Health and Human Services’ Advisory Committee on Heritable Disorders in Newborns and Children, and includes the Recommended Uniform Screening Panel (RUSP).
Occasionally, states may add disorders through legislative routes motivated by parents, disorder advocates and/or specialists, researchers and clinicians. These disorders can be unique to certain states’ screening panels and may not necessarily be screened nationally.
