The non-invasive prenatal test method has come a long way and has proven 
its advantages over invasive methods again and again. It has the potential of 
detecting whether a baby is at any risk of genetic disorders like Down 
syndrome and Patau syndrome.
All this test needs to get that information is a simple blood test. It  greatly 
reduces the risk and pressure on the fetus just by being non-invasive.
How does scientist tap into fetal DNA using maternal 
blood?
This is the feature that makes this test so 
successful and efficient. The thing is 
during pregnancy about 10% of the total 
DNA of the mother contains fetal DNA. This 
fetal DNA circulating inside the mother’s 
body is what the scientist use to detect 
any genetic defect in the fetus. Scientists 
separate maternal DNA from fetal DNA to 
use as a sample.
NIPT has spread as a great alternative to 
invasive prenatal tests which include 
dangerous methods like amniocentesis 
and CVS.
NIPT produces very accurate results and looks out for any kind of chromosomal 
unbalance. Some of the reasons why the NIPT test took off was because:
This test can be done at the very early stages of the pregnancy and hence provides 
the family time to plan everything.
The risk of miscarriage is zero. So it is a pretty safe test and can be done easily.
No specialist is required to take the sample for the test, unlike prenatal test.
