Amniotic fluid aspiration is a method of examination. This type of examination method is mainly used during prenatal check ups, and of course, the examination has a certain time requirement. It is mainly conducted in the mid pregnancy stage and belongs to a prenatal diagnostic method. So, do amniocentesis pass through more often?
Amniotic fluid puncture is definitely successful, but there are also cases where it is not successful. The probability of passing amniocentesis mainly depends on the condition of the fetus. If amniocentesis is performed due to chromosomal abnormalities in the fetus, the accuracy of amniocentesis is relatively high, reaching 99%.
Of course, when performing amniocentesis, there are indeed other factors that can affect it. The main factors affecting the examination of these abnormalities are contamination of the pregnant woman's blood. However, these situations that affect amniotic fluid are relatively rare and require another extraction of amniotic fluid for examination. In most cases, amniocentesis rarely results in errors.
There is a certain time requirement for amniocentesis examination, and the best examination time is around 16 to 20 weeks of pregnancy. When pregnant women are older, that is to say, over the age of 35, they need to undergo amniocentesis examination. There is also a history of Down syndrome in the family, or individuals at higher risk of Down syndrome screening need to undergo amniocentesis.
