Newborn Screening Program

The Newborn Screening Area Service Center (NBS ASC) at Valley Children’s Hospital works to protect and improve the health of all babies born in California. Under the auspices of the Genetic Disease Branch (GDB) of the California Department of Health Services, The California Newborn Screening Program provides cost effective testing and follow-up, permitting early diagnosis of four congenital disorders, thereby minimizing or preventing adverse outcomes or other serious long term disabilities.

Newborn Screening is recognized nationally as an essential preventive public health measure. All states in the nation and the District of Columbia have established newborn screening programs. The State of California began its Newborn Screening Program in 1966 with the testing for phenylketonuria (PKU). In October 1980, the program was expanded to include galactosemia, primary congenital hypothyroidism, and a more comprehensive follow-up system. In 1990, screening for sickle cell disease was added to the State’s existing program. This also allowed for the identification of some of the related non-sickling hemoglobin disorders, including beta thalassemia major, and Hb E-Beta Thalassemia. In 1999, the Program implemented screening for hemoglobin H and hemoglobin H - Constant Spring disease.

About Newborn Screening

  • Fewer than 10% of babies born in the US currently get comprehensive screening for all metabolic, endocrine and hematologic disorders already detectable through existing routine newborn screening programs.
  • Six babies are born every day in the US alone that have disorders detectable through newborn screening, but go undetected because they aren't screened.
  • Newborn screening can detect more than 35 disorders.
  • Most disorders detectable through newborn screening are treated by diet restrictions.
  • Over 99% of the babies born in California are screened. The actual sample of newborn blood is obtained before the sixth day of life by a heel-stick. To decrease the chances of a false positive (requiring additional testing) or false negative (resulting in a missed case), the NBS Program requires that babies be screened when they are at least 12 hours of age.

Newborn Screening Team

Our staff consists of the RN project director, RN coordinators, a community liaison, and administrative support. Our medical director is Susan Winter, M.D., a Pediatric Medicine and Metabolic Geneticist.

Newborn Screening Services

The seven NBS ASCs across the state are designated and funded by the California Department of Health Services to provide:

  • Reporting to primary care providers and assuring follow-up of all screening referrals: inadequate specimens, positive results, untested newborns, and those who are screened too early.
  • Consultation and technical assistance to all Program participants (i.e., hospitals, physicians, public health departments, etc)
  • Training and educational activities to all participants and the community.
  • Monitoring NBS providers for compliance with state newborn screening regulations and guidelines.
  • The California Newborn Screening Program screens for several diseases, including Classical PKU, Galactosemia, Primary Congenital Hypothyroidism, and Sickle Cell Disease and other Hemoglobinopathies.

Newborn Screening Innovations

Very early detection permits the metabolic disorders PKU and galactosemia to be treated with a diet, and hypothyroidism with thyroid hormones, thus preventing the development of mental retardation and other severe health problems. Detection of sickle cell disease in newborns makes possible early entry into comprehensive care, which includes the initiation penicillin prophylaxis and parent education, factors which have been shown to reduce morbidity and mortality. Early detection of thalassemia disorders allows for close monitoring for infections and anemia. Ongoing health care and close monitoring help children with hemoglobin disorders stay as healthy as possible.
