Patient's question:
When are the Down syndrome screening and 4D ultrasound done? I'm pregnant now, but my parents are not around and my husband is training overseas. I don't know how to do the prenatal examinations.Doctor's answer:
Down syndrome screening in early pregnancy is usually performed around the 12th week of pregnancy, involving an NT scan, which may include an MRI examination. In the second trimester, it is done 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). The 4D ultrasound does not require an empty stomach and should be accompanied by one person.Patients undergoing 4D ultrasound can receive professional treatment while also using folk remedies as supplementary therapy. They should maintain a proper diet in daily life and avoid stimulating foods.
