Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? Did the baby stop growing after the NT test?Doctor's answer:
It is a nuchal translucency scan, commonly used for prenatal screening, which can help diagnose chromosomal diseases and early detect various causes of fetal abnormalities. If it exceeds 3mm, it often suggests adverse fetal outcomes. It is performed using BC (B-mode ultrasound). The Down syndrome screening generally detects 60%-80% of Down syndrome cases and 85%-90% of neural tube defects. A risk factor below 1/270 only indicates a lower risk and does not guarantee complete exclusion. However, from the detection rate perspective, the significance of the Down syndrome screening is still very high. The optimal time for the test is between weeks 14-20 of pregnancy. Since you are now 19 weeks, you should proceed with it as soon as possible.
