What is a one-sentence summary of the following article?
Your doctor may recommend that you do a prenatal screening for cystic fibrosis if the disorder runs in your family or if you are a carrier of the defective gene that causes it. The test is usually very accurate and can tell you if your baby's genes are normal or if they are at risk of developing cystic fibrosis. However, taking this test is a very personal decision that you should discuss carefully with your doctor and your significant other, if they're involved. Talk about the pros and cons with your doctor and educate yourself before you decide to have a test done. Your doctor will put a needle into your abdominal wall and then into your uterus. They will extract a small amount of fluid from the amniotic sac, which is the sac that is around your baby. This test can be done at your doctor's office and should not be painful for you. Another prenatal test involves the doctor threading a thin tube into your vagina and cervix until it reaches the placenta. They will then suck out a sample of the placenta for testing. The suction used will be gentle and should not be painful or uncomfortable for you.
Consider a prenatal test if you are pregnant and genetically prone to cystic fibrosis. Consider allowing your doctor to remove fluid from your amniotic sac. Talk with your doctor about taking a sample of your placenta.
