Patient's question:
Hello, my wife is now more than six months pregnant. During the prenatal check-ups, everything has been normal. However, I recently heard about two screening methods: non-invasive and amniocentesis. I would like to know what the differences are between non-invasive and amniocentesis.Doctor's answer:
If possible, you can directly choose non-invasive DNA testing, which provides more accurate results and greater peace of mind. Non-invasive DNA screening is a non-invasive fetal chromosome aneuploidy test (NIPT), which involves collecting the peripheral blood of the pregnant woman to extract free fetal DNA. Amniocentesis is performed through amniocentesis (amniocentesis) or chorionic villus sampling or umbilical cord blood sampling to obtain fetal cells for cell culture and karyotype analysis. Among these, amniocentesis is the most commonly used method, which is what is commonly referred to as amniocentesis.
