Conducting the DNA test of an unborn child will provide the family with almost all the information about how the child will be born. This is done through a DNA test during the pregnancy period. With such advancement of technology, a DNA test can now be conducted even before the birth of a child.
One of the main reasons why a DNA test is required during pregnancy is to find out the paternity of the child. Other various reasons is to find out whether the child is healthy and whether the child will be suffering from any kind of deformity or carry any genetically inherited disease.
The test is conducted during 10 weeks to 24 weeks after conception. The sample collection method varies according to the stages of the child’s growth. Like for example, in case the pregnancy is within 10 weeks to 13 weeks after conception, the DNA testing method is carried out by inserting a fine tube or a thin needle which is supported by ultrasound in the womb through the vagina in order to get a sample of the chorionic villi.
Similarly, when the pregnant mother is in the pregnancy stage from 14 weeks to 24 weeks, the DNA test conducted is known as Amniocentesis. Here too a needle or tube is inserted inside the womb with the help of ultrasound to collect a sample of amniotic fluid.
If the pregnant mother is more than 24 weeks after conception, there is significant risk of the unborn baby getting affected is more likely to take place. So during this period, doctors mostly advise not to go for a DNA test and infact advise to get a DNA test conducted once the baby is born.
Incase parents wish to take a paternity DNA test conducted on an unborn child, doctors most likely will not go for the test as it can be risky. Rather, they advise the parents to go for the test after the baby is born.
