Patient's question:
When is the time for the Down syndrome screening and the 4D ultrasound? Now that I'm pregnant, my parents are not around, and my husband is training overseas. I don't know how to do the prenatal check-ups.Doctor's answer:
Down syndrome screening in early pregnancy is usually done around the 12th week, involving an NT scan, which may include an MRI examination. In the second trimester, it is between the 15th and 20th weeks, requiring a blood test for Down syndrome screening, which must be done on an empty stomach. A 4D ultrasound examination is generally performed around the sixth month of pregnancy (between the 22nd and 28th weeks). For the 4D ultrasound, fasting is not required, but a companion is needed. Patients undergoing 4D ultrasound can receive professional treatment while also using folk remedies as supplementary therapy. It is important to maintain a balanced diet and avoid foods in daily life.
