Patient's question:
Now I am 22 weeks pregnant and want to go to the hospital for the Down syndrome screening. I don't know if I can still do it now?Doctor's answer:
Tang screen is a mandatory prenatal test during prenatal care, mainly by examining the comprehensive evaluation of the pregnant woman's blood to determine the probability of fetal Tang screen based on factors such as the pregnant woman's age, weight, gestational age, etc. Generally, Tang screen can be done between 16-20 weeks, and it cannot be performed after 20 weeks. You can now undergo non-invasive DNA screening, which is acceptable. Additionally, you can also have a 4D color ultrasound, which is also acceptable. During pregnancy, it is essential to regularly undergo prenatal care to ensure the health of the fetus. Pay attention to rest more during the day. For specific examinations, it is still recommended to go to a formal hospital and follow the guidance of a doctor to ensure the health of the fetus.
