About the Newborn Screening (NBS) Laboratory

The Tennessee Newborn Screening (NBS) Laboratory tests over 80,000 specimens each year. Tennessee Code Annotated Title 68, Chapter 5, Part 4 requires that all infants born in Tennessee receive screening for certain conditions. Laboratory tests are done to help find infants who may have one of the disorders or medical conditions.

Finding and treating these disorders early can prevent serious complications such as growth problems, developmental delays, deafness, blindness, intellectual disabilities, seizures, and sudden or early death.

 The newborn screening tests require a simple heel stick blood sample collected from newborns between 24-36 hours after birth. If the screening result for one of the laboratory tests is outside of the expected range, the program's Newborn Screening Follow-up nurses will immediately begin follow-up. This often includes contacting the infant’s physician to initiate a repeat screen, confirmation of a diagnosis, and treatment from a specialist if necessary.   

Newborn Screening Follow-up, housed in the Division of Family Health and Wellness, also provides parent resources and educational and training resources for providers
