If I'm pregnant, what can I do to check if my child has cystic fibrosis (CF)?

ANSWER

If you’re pregnant, a genetic test can show if the fetus has cystic fibrosis. There are two types of tests:

  • Chorionic villus sampling (CVS): This checks cells from the placenta. It’s done after 9 weeks of pregnancy, usually between the 10th and 12th weeks.
  • Amniocentesis : This test uses cells from the amniotic fluid. You can get it between the 15th and 20th weeks of pregnancy.
