Newborn Screening

Newborn screening identifies conditions that can affect a child’s long-term health or survival. Early detection, diagnosis, and intervention can prevent death or disability and enable children to reach their full potential. There are three parts to newborn screening: blood test, hearing screening, heart screening.
