Screenings—Newborns and Infants (Birth–12 Months)
Most newborns are born healthy and normal. However, there are some
health problems that may not be detected on a routine exam by your
baby's physician. This is why blood tests, or screenings, are used to screen newborns for certain genetic disorders. A filter paper blood spot sample is required by state law to be submitted to the Tennessee State Laboratory for every baby born in Tennessee.
A newborn baby may look perfectly healthy, but still have an inherited disease. To prevent the effects of disease, the sample needs to be drawn during the infant's first two to three days of life. Early diagnosis and treatment can make the difference between a child leading a relatively normal life or having more serious developmental delays, having long-term healthcare needs or even dying.
How and where is your baby tested?
Before your baby leaves the hospital nursery, his or her heel will be pricked and a few drops of blood will be collected. This blood specimen will be sent to the State Laboratory in Nashville for testing. The hospital will also provide you with a Parent Pamphlet giving you more details about newborn screening.
What is the parents' role?
After you get home from the hospital, you may be contacted by your baby's doctor or the local health department to bring your baby in for a repeat blood sample. It is important that you follow up quickly. If you have any concerns about the results of the screening tests, please contact your baby's healthcare provider.

In addition to the screening for genetic disorders, your baby’s hearing will also be checked soon after birth. Hearing screening is not a blood test. The test is very safe and painless (many babies sleep through the screening). Your baby may pass the hearing test or may need to be referred for further testing. Babies identified with a hearing loss will be encouraged to be evaluated at a genetic center. If your baby does not pass the hearing test, contact your baby’s medical provider or a hearing provider right away to schedule a follow-up appointment.
