When a baby is born, a small blood sample is taken. This sample is then screened for a number of genetic conditions. Starting in 2018, states began adding SMA to its list of conditions babies are screened for at birth. If a newborn screening result is positive for SMA, follow-up testing is required to confirm the diagnosis.
Newborn screening allows an infant to begin treatment before symptoms appear, when research suggests therapies may be most effective. For more information on what to do about a positive SMA screen, visit our Newborn Screening Q&A.
Once your child has been diagnosed with SMA, it’s important to quickly gain some understanding of the condition so that you can act quickly to seek treatment. With SMA, the earlier the treatment, the better. Cure SMA has support programs available to all SMA families who reside in the U.S. Most of these resources are provided at no cost.
