Patient's question:
I am a 40-year-old pregnant woman. During the screening test, it was found that the risk of Down syndrome was high at a ratio of 1:12.Doctor's answer:
Analysis of the condition: Hello, high-risk results from the Down syndrome screening are all recommended for prenatal diagnosis. The current standard is fetal chromosome testing through amniotic fluid or umbilical cord blood. Amniocentesis indeed carries risks, but the risk is much lower than that of cord blood.Recommendations: For the sake of your health and the baby's well-being, we recommend you undergo amniocentesis. There is also a method of testing fetal chromosomes by drawing blood from the mother, which has no adverse effects on the baby and has a very high accuracy rate, but it is not part of the diagnostic standard. You can learn more about this test on the BGI website, as some hospitals offer this service.
