Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? What does it mean for a pregnant woman to have a puncture?Doctor's answer:
The best time for amniocentesis is between 16 and 20 weeks. It is usually performed on pregnant women aged 35 or older. During the procedure, a needle is guided by ultrasound to extract a small amount of amniotic fluid. The sample is then sent to the laboratory, where it is cultured for approximately one and a half weeks to determine if the baby has any abnormalities, including cleft lip and congenital diseases. The gender can also be determined.
