Determining if a baby will have Down syndrome involves specific prenatal tests. Early in pregnancy, screening tests like the combined test (blood test and ultrasound) can estimate the chance of Down syndrome. For more definitive answers, diagnostic tests such as amniocentesis or chorionic villus sampling (CVS) are available. These tests carry some risks but provide a high level of accuracy. It's important to consult with a healthcare professional to understand the best option for your specific situation.

FAQs & Answers

  1. What prenatal tests can detect Down syndrome? Prenatal tests for detecting Down syndrome include screening tests like the combined test (blood test and ultrasound) early in pregnancy, and diagnostic tests such as amniocentesis and chorionic villus sampling (CVS) which provide more definitive results.
  2. Are amniocentesis and CVS risky for the pregnancy? Both amniocentesis and CVS carry some risks, including a small chance of miscarriage. It is important to discuss these risks and benefits with your healthcare provider to choose the best option.
  3. When is the best time to do Down syndrome screening tests? Screening tests like the combined test are typically done in the first trimester, around 11 to 14 weeks of pregnancy, to estimate the likelihood of Down syndrome.
