well, since you have cf you are carrying 2 mutations. If the babies father is a carrier you have a 50/50 chance of the baby having cf or just being a carrier and actually not having the disease. Since you carry your mutations and each parent passes one of those genes on... both of those are mutated in your case and your baby will be a carrier for sure. If the gene that the father passes is mutated, then you end up with a baby with cf. They will follow up with genetic testing for the baby and a sweat test. There are false postives on the newborn screening, but with yourself actually having cf, and cf on the fathers side...your chances are increased. I'm really surprised that your doctor did not refer you for genetic counseling so that you were aware of the odds ahead of time.
Best of luck to you with all of the future testing.. and congratulations on you baby!
* I wanted to add that if the father is not a carrier, then your baby will just be a carrier and there is no chance of cf. That might be one of the steps of your healthcare team ... to run genetics him to determine his carrier status.
