Cystic Fibrosis Carrier Screening - What If I Am a Carrier?

If tests show that you are a carrier of cystic fibrosis (CF), your partner should also be tested. Both parents must be carriers of CF for a child to have the disease. If tests show that your partner is not a carrier of the CF gene, there is a very small chance that you will have a child with CF.

If you and your partner are both carriers of CF, there is a 1-in-4 (25%) chance that your child will have CF.

  • If you are not already pregnant, you may wish to have genetic counseling to understand your risks and options if you decide to have children.
  • If you are already pregnant, you may wish to have further testing (amniocentesis or chorionic villus sampling) to determine whether your baby has CF.
