Newborn Screening

If your child has a positive NBS (newborn screen) result for Cystic Fibrosis, a sweat test is recommended for further diagnostics. Please have your Pediatrician send an order to our Sweat laboratory for an appointment.

Dell Children’s Medical Center has one of the few Texas certified Sweat Testing laboratories. The Laboratory is open M-F and testing can be scheduled by appointment and physician order only.

Sweat Testing is a non-invasive procedure that normally lasts 30 minutes to 1 hour. Test results are usually reported within 24 hours to your pediatrician and the Cystic Fibrosis Clinic.
