Patient's question:
Hello doctor. I've always been confused whether the Down syndrome screening involves an ultrasound. Could you explain it to me?Doctor's answer:
Down syndrome screening mainly involves blood tests for detailed examination. If it is within 11 to 13 weeks and 6 days of pregnancy, an NT test needs to be performed. This test requires a color Doppler ultrasound, which is an early Down syndrome screening. Generally, the Down syndrome screening we usually refer to is done between 15 to 20 weeks of pregnancy through blood tests. It is recommended to regularly visit the hospital for prenatal check-ups, drink more water, get adequate rest, maintain a balanced diet, and can take calcium supplements.
