Understanding the Role of Genetics and Prenatal Diagnostics

If you know genetic problems run in the family, we provide preconception counseling to help you understand any risks.

Once you are pregnant, we offer many types of prenatal diagnostics and testing to identify any genetically based issues and other potential problems:

  • Triple or quad screening, to test the fetus for chromosomal abnormalities (e.g., Down syndrome) and neural tube defects (e.g., spina bifida). Done at 16 weeks.
  • Nuchal translucency testing, an ultrasound test to help identify signs of Down syndrome and congenital heart defects. Done at 11-13 weeks.
  • PAPP-A, a genetic screening test often combined with the results of the nuchal translucency test to help identify markers for Down syndrome. Done at 11-13 weeks.
  • Amniocentesis, a sampling of the amniotic fluid that can be used to check for chromosomal abnormalities, fetal infections, Rh incompatibility, and other issues. Done between 15 and 20 weeks.

We encourage you to talk to our physicians if you have any questions or concerns about genetics issues and the prenatal diagnostics that can help to identify them.
