When a woman learns that she is going to be a mother a lot of information starts flowing towards her regarding pregnancy, diet, health, family support, exercise, and an early decision of whether to have the unborn baby checked for any kind of genetic disease or not.
Although there are many parents who choose to get an early DNA test to find out about any kind of complication that might make the pregnancy difficult or cause any kind of disorder in the offspring very few of them know about the procedures and risks related to some kind of prenatal testing.
And to clear the fog it is better to get as much information about the tests as possible. There are many screening and diagnostic testing options to choose from at your convenience.
Screening is done in the first trimester of pregnancy where the mother’s blood and ultrasound are used to detect the back of the neck of the unborn baby to check any signs of down syndrome in the child.
Cell-free DNA screening is done by using the mother’s blood to find the fragments of DNA of the child to determine any kind of genetic defect in the child. The risk related to pregnancy caused by screening tests is very low and it is often considered safe for both the baby and the mother.
In the diagnostic test, tests like CVS and amniocentesis are used to collect the sample directly from the fetus and can cause several risks.
