Kids in America: Newborn Screening for Cystic Fibrosis

Within the last year, all 50 states in the United States have adopted newborn screening (NBS) protocols for cystic fibrosis (CF), the most common fatal autosomal recessive disease among Caucasian populations. In this overview, we discuss the rationale for implementing NBS for CF and discuss the different testing algorithms states have adopted. Based on studies in the United States, Australia, and the United Kingdom, these measures will likely lead to less severe disease, prolonged life, and more cost-effective management of CF in the long run.
