About Newborn Screening
About Us

The Texas Newborn Screening (NBS) Laboratory tests nearly 800,000 specimens each year. Texas law (Health and Safety Code, Chapter 33) requires these laboratory tests to help find infants who may have one of 53 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 one to two days after birth. A second sample is collected when the baby is one to two weeks of age. If the result for one of the laboratory tests is outside of the expected range, the NBS Program's Clinical Care Coordination Group will immediately begin follow-up with a healthcare provider. Two point of care screens are also conducted at the birthing facility.
