In other words, the DNA test is performed while the mother is still pregnant.
In this guide, we provide a full breakdown of everything you need to know about prenatal DNA paternity testing, how it works and when you should consider taking a test.
How does a prenatal paternity test work?
The testing process for prenatal DNA paternity testing is based on the same principle as a standard DNA paternity test.
By examining the baby’s DNA together with the parents’ DNA, it is possible to identify which half of the DNA is inherited from the mother and which half is from the father.
If the tested man in indeed the biological father of the baby, both will share DNA. When the tested man is not the biological father, there will be differences in the DNA of the man and the baby.
Can I get a paternity test while pregnant and is it safe?
The first question that many people ask about prenatal paternity testing is ‘can I get a test while pregnant?’
The simple answer is, yes.
AlphaBiolabs’ prenatal paternity testing is non-invasive and uses cheek (buccal) swabs from the alleged father and the mother (pregnant woman), along with a blood sample from the mother to determine whether the man is the biological father of the child.
A blood sample is only needed from the mother, which is taken from her arm, and no needles need to be inserted into the womb. As a result, there is no risk to the mother or the unborn child when taking this test.
What is a non-invasive prenatal paternity test (NIPP)?
A non-invasive prenatal paternity test is the safest and most accurate way to establish paternity during pregnancy.
Unlike other tests which involve taking cells from the placenta (chorionic villus sampling or CVS test) or extracting a sample of amniotic fluid (amniocentesis), all that is required for a NIPP test is a blood sample from the mother, and cheek (buccal) swabs from the mother and alleged father.
A NIPP test is the only prenatal paternity test that poses zero risk to mum or the unborn baby.
How early can I do a paternity test?
A prenatal DNA paternity test can be performed as early as seven weeks into the pregnancy, or nine weeks since the mother’s last period.
How is a prenatal paternity test done and what samples are required?
To perform a non-invasive prenatal paternity test, we need to look at three samples:
- The man’s DNA (alleged father) – collected using cheek swabs
- The pregnant woman’s DNA – collected using cheek swabs and a blood sample and
- The unborn baby’s DNA – identified via the mother’s blood sample
The baby’s DNA is passed into the mother’s bloodstream via the placenta during pregnancy. The test is performed by analysing the baby’s DNA and comparing DNA markers to that of the parents.
How are the samples collected?
Once you have ordered your test, we will contact you to arrange collection of the mother’s blood and cheek swab samples and the father’s cheek swab samples FREE OF CHARGE at our Dublin walk-in centre.
The mother and alleged father do not have to attend the same appointment at the Dublin walk-in centre. However, we do recommend that both the mother and alleged father’s samples are collected around the same time.
This is because blood samples are time-sensitive and must be returned to the laboratory as soon as possible after collection, along with all cheek swab samples.
It’s important to note that a prenatal paternity test cannot be performed without the consent of all parties involved in the testing (the woman and the alleged father(s)).
How do we know if the man is the biological father of the baby from a prenatal paternity test?
Once both the mother and alleged father’s samples have been received, the samples are sent to AlphaBiolabs’ laboratory where DNA is extracted from both parents’ samples.
DNA from the alleged father’s sample is extracted from the cheek cells collected via the mouth swabs. The isolated DNA samples are then amplified, and state-of-the-art equipment is used to carry out Massively Parallel Sequencing (MPS) – also known as Next Generation Sequencing (NGS) – to analyse up to 153 DNA markers.
By comparing DNA markers in the baby’s DNA profile with the alleged father’s profile, it is possible to identify DNA that has been inherited from the biological father of the child.
If the man tested is indeed the biological father of the baby, both will share DNA in common. When the tested man is not the biological father there will be differences between the DNA of the man and the baby.
How much does a prenatal paternity test cost?
AlphaBiolabs’ prenatal DNA paternity testing starts at €995 with results in five to seven days.
For an additional €200 we can provide results in four days.
We are the only company to offer guaranteed results, or your money back. You can also spread the cost of the test with interest-free credit if needed.
How conclusive are the results of the test?
We can provide a 99.99% probability of paternity where the father is confirmed as the biological father.
However, the scientific limitations of prenatal paternity testing mean that in a very small number of tests, a conclusive result is not always guaranteed.
Although other testing companies may promise guaranteed results, this is not true.
As a trusted and accredited laboratory, it is important for us to make you aware of this outcome.
In a small number of cases, the mother’s blood sample may contain insufficient cell-free DNA (cfDNA) from the foetus, which can lead to an inconclusive result.
How accurate are prenatal DNA paternity tests?
Our prenatal paternity test results are extremely accurate based on the samples we receive. We also test all our exclusion results twice, so you can be sure your result is highly accurate.
What happens if my prenatal paternity test result is inconclusive?
In the event of an inconclusive result, we offer an additional free of charge test with a newly collected sample, two weeks after the first test.
If this test is also inconclusive, we will perform a third and final test, also free of charge, after another two weeks. Please note that you are responsible for the cost of all blood sample collections.
In approximately 3-5% of cases, foetal DNA never reaches a sufficient level for successful testing. If this happens, AlphaBiolabs promises to refund the cost of your prenatal paternity test.
We are the only testing company that offers this money-back guarantee.
Please note that if you decide to cancel your test before we have had time to analyse all three samples, no refund will be paid due to the high cost of analysis.
Is a prenatal paternity test right for me?
A prenatal paternity test can provide peace of mind in circumstances where you are unsure of who is the biological father of your baby.
We know the sensitivities involved with a prenatal paternity test which is why your test is performed in complete confidence.

Types of prenatal paternity test
At AlphaBiolabs, we offer non-invasive prenatal paternity testing only, using cheek (buccal) swabs from both the mother and alleged father, and a blood sample from the mother.
However, there are other options available for people seeking a prenatal paternity test.
These include a chorionic villus sampling (CVS) test or an amniocentesis test.
What is a CVS (chorionic villus sampling) test and how is it performed?
For a CVS test, a small sample of cells is taken from the placenta and tested against cheek swabs from both the mother and the alleged father.
The cells are obtained from the placenta by guiding a thin tube through the cervix or using a needle inserted into the uterus to remove a sample of chorionic villus cells.
The test can be taken from as early as 10 weeks into pregnancy. However, unlike a non-invasive test, it is not without risk.
In fact, a CVS test poses a 1% risk of miscarriage. In about 5% of patients, a CVS test is not possible, meaning a non-invasive test – such as that offered at AlphaBiolabs – or an amniocentesis test would be required.
What is an amniocentesis test and how is it performed?
An amniocentesis test can be done between 14 and 20 weeks of pregnancy and is more commonly used to detect chromosome abnormalities or genetic disorders in the unborn foetus.
For an amniocentesis paternity test, your doctor will use a long, thin needle, which is inserted into the abdomen to extract a sample of amniotic fluid from the uterus.
This fluid is then used to retrieve foetal DNA, which is compared to the DNA collected from cheek swabs from the mother and alleged father.
As with a CVS test, amniocentesis poses a small risk of miscarriage (0.5%).
What are the main reasons for taking a prenatal paternity test?
For peace of mind prenatal paternity tests, finding out whether the man is the biological father of the child can have a profound impact on families, especially if the man is found not to be the child’s biological father.
In these cases, knowing early as to whether the man is the child’s biological father can help people make important decisions about the pregnancy.
For legal proceedings, knowing the biological father of the child in early pregnancy can help local authorities and social workers to put plans in place to safeguard a child who might be at risk.
It allows local authorities to perform assessments early in the process, as well as providing time to develop a good working relationship with both the mother and father, especially where there are concerns.
In these cases, a legal prenatal DNA test would be required.
