Non invasive DNA is a very important test in prenatal examination, mainly to check the chromosomal condition of the fetus, and determine whether the fetus is healthy and whether there are any abnormalities based on the chromosomal condition of the fetus. Pregnant women have different prenatal check ups every month, so they need to undergo them under the guidance of a doctor. So, how many months can non-invasive DNA be done?
The optimal time for non-invasive DNA testing is between 15-20 weeks of pregnancy. Non invasive DNA testing involves collecting blood from pregnant women to detect the chromosomal status of the fetus. Non invasive DNA testing can provide insights into fetal development and determine if the fetus has chromosomal abnormalities, making it an important examination that needs to be performed at the optimal time.
In addition to non-invasive DNA testing, there are many testing items for pregnant women throughout the entire pregnancy, such as the need for prenatal ultrasound screening. Pregnant women need to have blood sugar and blood pressure checks every month, as well as check the fetal heart rate and fetal movement. In the later stages of pregnancy, pregnant women need to count fetal movements themselves.
In general, non-invasive DNA testing can be done at 15-20 weeks of pregnancy in women. In the later stages of pregnancy, pregnant women need to count fetal movements themselves because the frequency of fetal movements can reflect the health of the fetus. If fetal movements are too frequent in the short term, it may indicate a possibility of hypoxia in the fetus, and it is necessary to go to the hospital for examination in a timely manner. If necessary, oxygen therapy may also be needed.
