When pregnant, in order to ensure that all physical indicators are normal, it is usually necessary to undergo many tests, which are also to understand the development of the baby in the fetus. Among numerous examination items, non-invasive DNA and amniocentesis are relatively common. So, does a low-risk non-invasive DNA still require amniocentesis?
Non invasive DNA is already in the low-risk range, so there is no need for amniocentesis after that. The success rate of non-invasive DNA testing is relatively high, and it is also low-risk. Pregnant women do not need to worry too much about the results, so as not to be nervous and affect the test results. Amniotic fluid aspiration is just a test, mainly to check whether the fetal chromosome condition is abnormal and whether there is a risk of Down syndrome.
During pregnancy, B-ultrasound examination is also essential. B-ultrasound can be used to understand the situation of other indicators. If there are any abnormal indicators, amniocentesis can be performed to confirm the details. If there are no issues with the indicators, pregnant women can continue to take care of their pregnancy with peace of mind.
The non-invasive DNA risk is low, so there is no need for amniocentesis. However, there are also some special situations that require amniocentesis, such as parents with chromosomal abnormalities or a family history of hereditary diseases. In this case, it is best to undergo amniocentesis, which is more secure and can also determine whether other examination items have abnormalities. In addition, if pregnant women have received blood transfusions or undergone surgery within one year, or if abnormal fetal development is detected by ultrasound examination, it is best to undergo amniocentesis.
