If you or your partner has close relatives with cystic fibrosis, you both might want to undergo genetic testing before having children. The test, which is performed in a lab on a sample of blood or saliva, can help determine your risk of having a child with cystic fibrosis.
If you're already pregnant and the genetic test shows that your baby may be at risk of cystic fibrosis, your doctor can conduct additional tests on your developing child.
Genetic testing isn't for everyone. Before you decide to be tested, you should talk to a genetic counselor about the psychological impact the test results might carry.
