In brief: After
Generlly, it is diagnosed afterwards brought standard genetic screening tests, or a sweat chloride kin test if it is an unusual type.

In brief: Genetic testing
A baby can only have cystic fibrosis (CF) if both parents are carriers of a CF mutation; even then the chances are 1 in 4 with each pregnancy.
If both parents test positive for a CF mutation then the fetal status can be measured via amniocentesis with genetic testing of the baby's cells. This testing is readily available in the United States.
