Prenatal DNA testing can be done by 2 types such as screening and diagnostic. In screening tests, doctors check the risks of genetic disorders in your baby and a diagnostic test includes detection of any certain genetic disorder present in the fetus.
There are 3 main prenatal DNA testing as follows:
This testing is also called cell-free DNA screening and is a blood test in which a doctor checks the DNA from the placenta that is found in the mother’s blood. This screening test is preferred for Down syndrome and Trisomy 18 chromosomal abnormalities.
Chorionic Villus Sampling (CVS)
This test is done in the first trimester of the pregnancy period. In this case, the tissue is taken from the placenta with the help of a thin tube that is inserted into the vagina. This CVS technique is very helpful in detecting various genetic disorders. Apart from this, the CVS DNA paternity test is also very much in use.
In Amniocentesis, doctors remove amniotic fluid from the uterus. In this second trimester diagnostic test, a needle is inserted through the abdomen and then into the vagina. This needle withdraws some fluid from the womb.
