Is a Paternity Test While Pregnant Safe? The Pros and Cons of DNA Testing

  • Chris Powell

Are you pregnant but don’t know who the father is? Are you filled with dread at the thought of navigating the next 9 months alone – dodging the endless questions regarding the baby’s paternity? Do you want to find out the answer now instead of waiting until birth?

You’re in luck. Thanks to advances in science and technology, you no longer have to wait until birth to find out the paternity of your baby. Nowadays, there are multiple prenatal paternity test options available.

There are many benefits to taking advantage of these prenatal tests and establishing paternity during pregnancy. This can help both you and your baby through your pregnancy and after delivery.

If you’re interested in getting a paternity test while pregnant, check out the pros and cons of different DNA testing below!

Types of Paternity Test While Pregnant

There are three main options for paternity testing while pregnant. Each of these options involves different methods of obtaining DNA and analyzing it. Check out more information on each test as well as its pros and cons.


Amniocentesis is a prenatal procedure that is typically done for genetic testing. While it can establish paternity, it is more commonly performed to determine if a baby has any birth defects.

In order to complete this, the doctor inserts a needle into the uterus through the pregnant woman’s stomach. Using that needle, the doctor collects amniotic fluid from the uterus. This sample is then sent to a lab for testing.

This invasive procedure can only be performed between 15 and 18 weeks of pregnancy. It must be performed by a doctor.


Amniocentesis is very accurate – with an over 99% accuracy rate. One of the benefits of amniocentesis is that you can also find out if your baby has any birth defects such as spina bifida.


Amniocentesis is risky. Because the doctor is penetrating the uterus with a needle, there is a small chance of miscarriage – about 0.2 to 0.3%

Amniocentesis also has other risks such as risk of infection, amniotic fluid leak, and even injury to the baby via needle. While these are rare, it is something you must consider before having an amniocentesis.

Most doctors will also not perform an amniocentesis for paternity reasons due to these risks.

Chorionic Villa Sampling (CVS)

Chorionic Villa Sampling – or CVS – is another procedure that is used to typically test the baby for potential genetic issues.

This procedure can be done one of two ways. The doctor can either insert a thin tube into the vagina and cervix to grab a sample of chorionic villus tissue from the placenta.

Like an amniocentesis, the doctor can also insert a needle through the woman’s stomach into the uterus. Unlike an amniocentesis, the doctor then uses the needle to remove some chorionic villus tissue from the placenta instead of amniotic fluid. The sample is then sent to a laboratory for analysis.

This procedure is done between weeks 10 and 12 of pregnancy and must be performed by a doctor.


Like the amniocentesis, this test can detect many genetic issues such as Down Syndrome. It can also be done earlier in pregnancy than the amniocentesis. This makes it a great option for someone that is looking for answers earlier in their pregnancy. CVS is also over 99% accurate.


This is an invasive procedure that has many risks. There is a risk of miscarriage with CVS. There are also risks of bleeding, infection, and premature labor.

Only doctors can perform a CVS and typically will not do one for the sole purpose of paternity testing.

Non-Invasive Prenatal Paternity Test

The Non-invasive Prenatal Paternity (NIPP) test is a recent development in paternity testing. No longer do you have to have either a risky amniocentesis or a CVS performed during pregnancy to find out your baby’s paternity. Now, all you need to do is a simple blood test.

NIPP tests are very simple. The pregnant mother will need to go to a laboratory for bloodwork. They’ll likely take 1 to 2 vials of blood from the mother. The alleged father will also need to provide either a blood sample or cheek swab at the same time.

After both samples are taken, they're sent to a lab for analysis. The lab will then analyze the pregnant woman’s blood and the alleged father’s DNA sample.

The lab can isolate the fetal DNA from the mother’s blood and then use this to compare it to the father’s DNA. This will establish whether or not the alleged father is truly the biological father.

This test can be performed as soon as 8-9 weeks in pregnancy. To learn more about what is involved in NIPP testing, check out this blog here


The NIPP test has many great pros. It can be performed earlier than both amniocentesis and CVS. You don’t need any doctor involvement for this test. You simply order a test online and get the bloodwork done at a local laboratory.

This is also non-invasive. You won't have any needles or tubes inserted into your uterus. There aren’t any risks of miscarriage or other issues that come with amniocentesis and CVS.

It is completely safe for both mother and baby. It is also extremely accurate with an over 99% accuracy rate.


The great thing about NIPP is that aren’t any risks with this procedure. It will not cause a miscarriage, vaginal bleeding, or infection. All you need to do is complete bloodwork which is a standard procedure in all pregnancies.

Since there are no cons with the NIPP, this is the perfect solution for anyone looking for prenatal paternity tests. This prenatal paternity DNA test is a great choice for anyone searching for one.

You’ll have results within 2 weeks with a 100% accuracy rate! You can also learn the sex of your baby. 

Safe Prenatal Paternity Test

If you’re looking for a safe prenatal DNA test, the non-invasive prenatal paternity test is the best option for you. There are no risks and so many benefits in establishing paternity early in pregnancy.

Knowing the paternity helps foster a bond between father and baby prior to birth. The father is also more likely to emotionally and financially support you if they know that they are the father.  On top of that, you can agree to child support and other arrangements ahead of delivery.
