Comparing Different DNA Testing Procedures
Comparing Different DNA Testing Procedures

Many people may choose to undergo a DNA test while pregnant for a variety of reasons. If you do your research online, you’ll find that there are a few known ways to go about that. While you can have the test done after you give birth, there are plenty of reasons that you may prefer it done sooner.

 

In today’s blog, we will discuss the three main types of DNA testing that can be done before the birth of a child.

 

 

Amniocentesis

 

 

This option is possible at around 14 - 20 weeks pregnant. There’s some risk involved because the doctor has to insert a needle into your womb to get through the amniotic sac where a sample fluid will be drawn. While it can also be used for DNA testing, it is chiefly recommended for those faced with the probability of premature birth and other genetic abnormalities. 

 

 

Chorionic Villus Sampling or CVS

 

 

Same as amniocentesis, CVS is also an invasive procedure. It can be performed as early as 10 weeks. It uses a needle which is inserted through your cervix to get a chorionic villi sample from the uterine wall. The sample drawn should contain the genetic code of your child which can then be compared to the DNA of the probable father. While this is one of the options of a DNA test while pregnant, your doctor must consent to it as it involves a small risk of miscarriage.

 

 

Non-invasive Prenatal Paternity Testing or NIPP

 

 

If you are looking for the most non-invasive DNA test while pregnant, this is the option for you. It can be done as early as the 7th week of your pregnancy. Unlike the invasive procedures identified above, NIPP only requires a blood sample from you and the probable father. Your blood sample will contain fragments of your unborn child’s DNA, which is what allows for the test to determine paternity. This DNA test while pregnant is the safest.

Thanks, I was having difficulty understanding the different types of DNA tests.
