The State of Maryland and the Office of Children and Youth with Special Health Care Needs are committed to identifying serious health conditions in newborns early—before symptoms appear. Newborn bloodspot screening began in 1965 with testing for Phenylketonuria (PKU), a rare metabolic disorder. Since then, the program has expanded to screen for over 60 conditions

All newborns in Maryland are screened twice:

  • 24–48 hours after birth in the hospital
  • Around 2 weeks of age at a follow-up pediatric visit

Early detection allows for timely treatment and can prevent serious illness, developmental delays, and even death.
