DSHS has implemented a two-screen system to maximize the effectiveness of testing for all disorders on the Texas Newborn Screening Panel.
Two screens are completed in Texas to detect some of the disorders at the earliest possible opportunity. The first screen should be collected between 24 to 48 hours of age and the second screen between 7-14 days of age.
In Texas, the second screen routinely detects babies at risk for severe medical complications. These babies sometimes have a normal first screen.
After a baby is born, their physiology changes rapidly and sometimes it takes a week or more for these changes to occur. In some cases, a disorder may only be detected on the second screen due to these physiological changes.
In addition, some disorders (like cystic fibrosis) rely upon both newborn screens to reduce the number of babies who would otherwise require additional testing with a specialist to determine whether they have the condition or not.
The goal of the Texas Newborn Screening Program is to identify babies who have these devastating diseases before symptoms arise so that they can receive appropriate treatment and lead productive and healthy lives. Having a second screen improves medical providers’ ability to identify children with disorders who would have otherwise gone undetected.
