Testing

Newborns

All 50 states and the District of Columbia screen newborns for cystic fibrosis withing three days after birth. Testing identifies babies who are at high risk of having CF. If a baby has a positive screening for CF, a painless sweat test usually follows to rule out or confirm a cf diagnosis. 

Adults

Adults may also seek genetic testing for CF to help identify carriers who could pass the disease onto their children. Genetic testing is also available to confirm a CF diagnosis in adults.
