Question
We have a child with Down syndrome at home, and I am currently 24 weeks pregnant. I have undergone NT, early Down screening, and mid-trimester Down screening, all with low risk. The 4D ultrasound has also been completed. The fetus’s nasal bridge seems lower, and I am worried whether it is a child with Down syndrome. Should I undergo non-invasive DNA testing or amniocentesis?
Answer
Although there is a child with Down syndrome in the family, the early and mid-trimester Down screening results show low risk, indicating that the baby should be fine. Since all detailed examination results are normal, the baby should not have any abnormalities. If any abnormalities are found in the 4D ultrasound, the doctor will inform you and suggest further examination. Since no abnormalities have been reported by the doctor, you should feel reassured.
