Pregnancy is very important for every woman. After pregnancy, most pregnant women choose to pay attention to the condition of their unborn fetus through prenatal check ups to ensure its health, so that timely treatment can be taken if there are any problems. So, how many weeks is appropriate for prenatal diagnosis?
Firstly, prenatal diagnosis can be conducted throughout the entire pregnancy. It refers to a series of detailed examinations conducted before the birth of the fetus, including the developmental status of the fetus, whether the fetus and pregnant woman have certain diseases, or whether the pregnancy is normal. This can detect diseases in advance and provide timely treatment, or it can also detect incurable diseases as early as possible, allowing parents to decide whether to continue the pregnancy. Prenatal diagnosis can be conducted for different purposes and reasons in different pregnancy cycles.
If abnormalities are found in the fetus during early or mid pregnancy, a chorionic villus biopsy can be performed around 12 weeks of pregnancy. If it is in mid pregnancy, amniocentesis can be performed to collect amniotic fluid for diagnosis. If it is in the middle and late stages of pregnancy, umbilical cord blood puncture can even be performed on the fetus, which can take the fetal umbilical cord blood for prenatal diagnosis. Through prenatal diagnosis, parents can confirm whether the fetus is normal and prepare and plan for the arrival of the baby in advance.
