Top 4 Things You Need to Know About Cell Free DNA Testing

Category : Business · by Jun 7th, 2019

When you’re an expecting mother, the only thing you really and truly worry about is whether or not the child growing inside of you is healthy and developing correctly. However, due to extreme advances in modern technology within the last decade, it’s now possible to learn if there are any chromosomal abnormalities with the fetus long before they are born.

A cell free dna test is a great way to determine if your future child will have to face serious issues, allowing you to prepare properly ahead of time. Here are the top four things you need to know about this testing before you agree to have it done or decide to pass it up today.

1. What Can You Test for?

When you agree to take part in a prenatal DNA testing, you can rest assured knowing that you’ll be able to determine whether or not your developing baby has Down syndrome, trisomy 18, or trisomy 13.

While these are the standard screenings, your doctor may also use the test to look for triploidy, sex chromosome aneuploidy, microdeletion syndrome, and other single gene disorders if he or she believes there is a reason to do so.

2. When Can You Get the Test Done

A cell free DNA test can be performed on any pregnant woman after the 10-week mark. This is to make sure that the fetus has reached an acceptable age where the blood sample will be more accurate, in addition to guaranteeing that the pregnancy has a better chance of reaching term.

Women are much more susceptible to miscarriages during their first trimester, and placing them in a situation where they feel mistrust or guilt over that loss can be devastating. The best thing is to let this time pass as naturally as possible, continuing with further testing later on down the line.

3. What Can Affect the Results?

While this prenatal testing is considered to be extremely accurate, there are certain factors that can have an impact on the results, including the number of fetuses being carried by the mother, the weight of the mother, the use of donor eggs, being less than 10 weeks pregnant, and even having taken certain blood thinners.

Your doctor will know if any of these issues are a concern when it comes to your results and will be able to steer you in the best direction regarding your particular situation and circumstance.

4. How Is the Test Performed?

This DNA test is actually incredibly easy, despite everything you can learn from it. Just like when you have any other standard blood work done, a blood sample will be taken from the mother which will then be analyzed by a lab who will separate the fetal blood and the maternal blood, allowing them to check for specific chromosomal abnormalities.

The more you know about the conditions your child has, the better you’ll be able to prepare for their future. These tests can help parents make the right decisions regarding their future family, making them a great benefit to anyone who feels it may be necessary.
