If you were a carrier of cystic fibrosis, how do you test to see if your unborn child has inherited it?

In brief: CF

First you need to determine if the father of the baby is also a carrier of the disease as CF is a recessive disease.
Therefore both parents need to be carriers and even then there is only a 25% chance the baby is affected. Doing either cvs or amnio can determine if the fetus is affected by cf. If only one parent is a carrier. Screening post natal is recommended.
