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.
