Information for Midwives and Community Birth Providers

Newborn screening is a critical preventative measure. It allows for the early identification and treatment of health issues to prevent serious illness, disability, or death. Early identification and treatment promote healthy child development and overall quality of life for newborns and their families. 

Midwives play a key role in promoting the health and well-being of babies and families. By educating parents about evidence-based newborn screening benefits and options, midwives can engage families in informed choice discussions. This web page contains information specifically directed for midwives and community birth providers.

In California, newborn screening blood collection needs to be done from 12 to 48 hours after birth, with 24 hours being the optimal time for collection. The specimen needs to be shipped to the processing laboratory using the preferred California Newborn Screening (NBS) Program vendor so that it is received within 48 hours of collection.

Additional information, including a list of disorders tested for on the NBS Program screening panel and how to get results, can be found through the NBS Program landing page

Please visit the California Prenatal Screening Program landing page for more information on the options available to all pregnant people in California to check fetuses for genetic conditions and birth defects.
