Pregnant women need to undergo various tests from the beginning of pregnancy, first to check their progesterone and then HCG. They need to undergo a pregnancy test once a month based on the fetal development time. Non invasive DNA testing is a type of prenatal examination that belongs to screening for abnormalities. So, how many weeks is the most accurate for non-invasive DNA testing?
Every pregnancy test should be conducted according to the time. If the fetal development is not good and some special items are checked at an inappropriate time, the effect will not be very good and the results will also deviate. If there are any abnormalities, they cannot be detected at this time.
Non invasive DNA testing should be performed between 22-24 weeks of pregnancy. At this point, the fetus has matured and all organs have fully developed, making the screening examination more thorough. Fetuses that are too small cannot undergo non-invasive DNA testing because the insufficient concentration of DNA in such fetuses can lead to inaccurate test results.
Non invasive DNA testing should not be done too early, nor too late. If it is too late, it can easily lead to inaccurate data results. It is not safe to have a check-up too late. If there are any problems with the fetus that cannot be resolved in a timely manner, it will be even more difficult to solve them later. Therefore, it is reminded that pregnant women should actively follow the doctor's advice and undergo relevant examinations at the correct time to accurately understand the development status of the fetus and ensure its healthy growth.
