Can you do paternity testing while pregnant?

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 is 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 DNA 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.

Why is it important to establish paternity during pregnancy?

Establishing paternity during pregnancy can be important for many reasons, both emotional and practical.

Knowing who the biological father is can help provide peace of mind for everyone involved and allow both parents to begin planning for the future with confidence. It also lays the foundation for a stronger relationship between the child and both parents from the very beginning.

Confirming paternity early on also establishes legal and social benefits for the child. These can include financial support, inheritance rights, and access to the father’s medical history, which may be helpful for healthcare decisions.

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.

Can my doctor/midwife do a paternity test while I’m pregnant?

No, your doctor or midwife cannot carry out a paternity test during pregnancy. Paternity testing is not part of routine NHS care and is not offered by healthcare professionals as a standard service.

If you are considering a paternity test while pregnant, you will need to arrange this privately through an accredited testing laboratory, such as AlphaBiolabs.

At AlphaBiolabs, we offer non-invasive prenatal paternity testing that can be performed from as early as 7 weeks into pregnancy. This test is 100% safe for both mother and baby, as it only requires a blood sample and cheek swabs from the mother and a cheek swab from the alleged father.

All testing is performed at our UKAS 17025-accredited laboratory, and we are the first UK laboratory to achieve accreditation for prenatal paternity testing.

If you’re unsure about the process or would like more information, our friendly team is here to help guide you every step of the way.

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?

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)).

Testing mum

With an AlphaBiolabs prenatal paternity test, there are three options for collection of the mother’s blood sample:

• The collection can be performed by a nurse or phlebotomist at a local medical practice
• AlphaBiolabs can arrange for one of its highly trained sample collectors to take the sample from any convenient location (your home or workplace, for example)
• You can choose to visit one of AlphaBiolabs’ nationwide Walk-in Centres. Here, both blood and mouth swab samples can be collected at the same time, which could save you money on collection fees

Blood samples are time sensitive and need to be returned to AlphaBiolabs’ testing laboratory as soon as possible after being collected.

This is to avoid degradation of the sample which can render a blood sample unusable. For this reason, the use of a trained sample collector is highly advised.

Testing the alleged father(s)

As in a standard DNA paternity test, the alleged father or alleged fathers’ sample(s) involve a mouth swab to collect DNA.

The mouth swab simply needs to be rubbed firmly on the inside of both cheeks for at least 20 seconds to collect cheek (buccal) cells. The man’s sample does not need to be collected at the same location as the mother’s blood sample; a sample collector can visit any convenient location.

However, the samples should be collected around the same time to avoid any delays to the results.

In both instances (testing the mother and alleged father), you can choose to visit one of our Walk-in Centres where our team will be able to perform the collection for you.

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?

Our peace of mind Prenatal Paternity test costs £695 for results in 3-5 business days*.

The cost of the test includes all fees for laboratory testing and analysis, as well as FREE sample collection at any of our nationwide walk-in centres.

You can also spread the cost of your test with a choice of finance options including:

• Pay in 3 interest-free payments using PayPal
• Pay in 3 interest-free payments using Klarna
• Various other flexible finance options – call 0333 600 1300 for more information

Please note: If you require a NIPP test for legal or official matters, you will need a legal prenatal DNA test.

Why are prenatal paternity tests so expensive?

Prenatal paternity tests are more expensive than standard paternity tests because of the advanced scientific techniques required to analyse foetal DNA while the baby is still in the womb.

Unlike postnatal paternity testing, which simply involves collecting cheek swabs from the individuals involved, a prenatal paternity test must carefully detect and isolate the baby’s DNA from a small blood sample taken from the mother. This is possible because, during pregnancy, tiny fragments of foetal DNA circulate in the mother’s bloodstream.

Highly specialised equipment and expert laboratory analysis are needed to separate and examine the foetal DNA from the mother’s own DNA.

At AlphaBiolabs, we have worked hard to make sure our Prenatal Paternity Testing remains extremely competitive, without compromising on quality. We also offer a variety of finance options to help you spread the cost of your test, including PayPal (pay in 3 interest-free payments), Klarna (pay in 3 interest-free payments), as well as other flexible finance options.

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.

In an extremely 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.

As a trusted and accredited UK laboratory, it is important for us to make you aware of this potential but very rare outcome.

How accurate are prenatal DNA paternity tests?

Our prenatal paternity test results are accurate based on the samples we receive.

Can I do a prenatal paternity test at home?

Yes, you can. For a prenatal DNA test to be performed at home, we can arrange for one of our specially trained sample collectors to visit your house at an agreed time.

This ensures that your samples are collected correctly (cheek swabs and blood sample for mum) and safely returned to our laboratory for testing.

Alternatively, we can send you a testing kit and you can arrange your own collections through your GP or another medical professional such as a trained nurse or phlebotomist.

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 miscarriage risk of between 0.5% and 1%. 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%).

Can I get a prenatal paternity test on the NHS?

The simple answer is no, you cannot receive any form of paternity test (standard or prenatal) on the NHS. However, as costs come down, companies like AlphaBiolabs making DNA paternity testing more affordable.

Before deciding to take a prenatal paternity test, it is a good idea to discuss it with your GP, who may be able to provide guidance on the options available to you.

Counselling can also help you work through your decision to take a test and the potential implications on yourself and your family.

If you choose to undergo a non-invasive prenatal paternity test, you can also arrange for your blood sample collection to be performed by a nurse or phlebotomist at your local medical practice.

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.
