Fetal DNA in maternal blood

During the pregnancy, your baby’s DNA circulates freely in your bloodstream. This allows the mother to perform prenatal tests to rule out the possibility of trisomies.


Trisomies occur when during the formation of the baby, some pair of her chromosomes instead of being two are three. This gives way to syndromes such as Down, Edwards, Patau, etc. This test is 0% risky for your baby, unlike amniocentesis.
