Paternity DNA Testing

DNA Testing During Pregnancy

A DNA Paternity Test is all about determining the probability of a biological relationship between a parent and their child, comparing the genetic profile of both. A series of highly variable DNA regions are characterized in the genetic profile.

What they do is identify and differentiate a person from any other, just like their fingerprint. There are two copies in these regions of DNA or genetic markers. One of maternal origin and the other of paternal origin, since our DNA’s genetic information comes in equal parts from each of our parents.

Therefore, a parent and their child undergoing a paternity study must share half of the markers that make up the genetic profile.

This same process to recognize paternity can also be applied to know any kinship, for example, between grandparents and grandchildren. Relationship tests are requested, especially when there is doubt about the family relationship in inheritance and immigration cases.

Paternity testing during pregnancy raises many questions. How do they work? What does the law say on this subject, and what are paternity tests carried out via the Internet worth? Here is what you should know about a pregnancy DNA test.


Why Does One Need a Paternity Test? How to Protect Yourself from Child Support Payment

You may request a paternity test if you doubt you are the biological parent of the unborn child. It can also be essential during child support tussles because one can confirm the other party is a biological parent to the unborn child and why they should take full responsibility.

Parents can also agree personally to opt for this kind of test to erase any doubts that may arise in the future.

To protect yourself from child support payments, you should first ensure that the child is indeed yours by taking a paternity test. You can take a pregnancy DNA test if your partner is still pregnant. If you are not the biological parent, you have a right not to take any responsibility.

You can also explain your financial situation to the court if you think you will experience any challenge. The other way to avoid paying child support fees is by obtaining full custody of the baby. You have to convince the court why you deserve full custody.  

Legal DNA Tests VS Personal DNA Tests

Anybody who wants a pregnancy DNA test can opt for a legal or personal test. A legal pregnancy DNA test needs a neutral third-party to collect your DNA samples. Professionals like doctors and nurses are the right persons in such a situation. A legal paternity test is usually admissible in court and can be used in child support or child custody cases.

A personal test, or what many refer to as home testing, is for personal information only. If you wish to know your personal paternity status where there are no legal implications, this kind of test is for you.

For personal tests, you can take the samples yourself anytime you wish. The legal paternity test requires the use of a certified lab and for the test to be conducted with proper chain of custody documentation for the samples taken and the testing procedures by laboratories specially approved for this purpose.  

What Is the Procedure?

It is possible to perform a paternity test during pregnancy to remove any doubt about an unborn child; this prenatal paternity test can be performed with a simple blood sample from the mother, which contains fetal DNA.

The other methods, called invasive (sampling villi through the cervix or amniocentesis), are heavier. As with classic paternity tests, the future baby’s DNA will be compared with the genetic markers of the presumed father. To be legal, these paternity tests must be part of legal proceedings.

The pregnancy DNA test can be carried out according to 2 methods: either a comparative examination of the blood or identification by genetic fingerprints (DNA test), generally using a saliva sample.

The genetic markers specific to each individual are analyzed—the objective is to find common characteristics between the supposed father and the child’s genetic imprint. The results are 99.99% reliable.  

Paternity Test During Pregnancy in Amniocentesis

This test is usually performed from a blood or saliva sample obtained from an adult or child. It can also be carried out during pregnancy to determine the paternity of the baby or fetus. In this case, the mother must undergo a procedure called amniocentesis between weeks 15 and 18.

Amniocentesis consists of obtaining a small part of the amniotic fluid surrounding the fetus by introducing a needle into the amniotic cavity through the mother’s abdominal and uterine walls. This liquid contains fetal cells from which we will obtain the DNA of the future baby and compare it with the presumed father’s DNA to confirm his paternity.  

Paternity Test During Pregnancy in Chorion Biopsy

An alternative to amniocentesis is a chorionic biopsy. Its main advantage over the previous one is that it can be performed earlier, between weeks 11 and 12 of gestation. This technique consists of obtaining placental tissue, abdominally or transcervically, from which the fetal DNA will be extracted.

Taking advantage of obtaining fetal material by either of these two procedures, some patients also decide to have a prenatal study to rule out possible chromosomal abnormalities in the fetus.  


The costs of a pregnancy DNA test may vary. The actual range is between $195 to $250 for most personal tests. You will be required to pay more for a legal pregnancy DNA test. This is because of the chain of custody protocols and increase in costs associated with certified lab testings. You are likely to spend $1500 to $1800 for a legal DNA test.  

Why It’s Good to Have a Paternity Test Done

One of the key benefits of undergoing a pregnancy paternity test is that it will help erase doubts between parents on whether the child is theirs. The kind of results you get will help you identify if you are the child’s biological parent.

It is also beneficial for parents who need child support. During child support cases, the court may require proof if one is the biological parent of a specific child.

This may also happen if one has part ways with their partner when they are yet to deliver. A pregnancy DNA test can help erase all the doubts and confirm that one is a biological parent to the unborn child.

They will be required to take full responsibility. A pregnancy paternity test offers couples the conformity and peace of mind needed. They will live peacefully, knowing they are the biological parents to the child.
