Newborn Screening (NBS) Data, Tennessee, 2015–2019
The Sickle Cell Data Collection (SCDC) program monitors and reports on the health of people with sickle cell disease (SCD) over time. Data from the state’s newborn screening (NBS) program are an important part of the SCDC program because they provide information about the SCD births that occur every year. Tennessee’s most recent NBS data, 2015–2019, are presented below.
The data provide the number of babies born with SCD in the state, their demographics, and their type of SCD. The people included in these data were born in Tennessee during 2015–2019 and reported by the state NBS program with a confirmed diagnosis of SCD.
The individuals in the NBS data are also included in the Tennessee SCDC program data for the years during which they were living in the state.
