100% safe, even in early pregnancy
Our prenatal paternity test carries no risk of miscarriage. It’s the UK’s most accurate non-invasive prenatal DNA test, and can be performed as early as seven weeks into pregnancy.
In-house prenatal DNA testing
We are the only UK laboratory to perform prenatal DNA testing in-house. We never send samples abroad. This allows us to test quickly, and helps to prevent blood samples from spoiling.
Our money-back guarantee
We can perform up to three DNA tests in order to determine paternity before a baby is born. If foetal DNA never reaches a sufficient level for testing, we promise to give you your money back.
AlphaBiolabs are the only testing laboratory in the UK to offer prenatal paternity testing in-house
We are accredited and regulated for testing in the UK, and therefore subject to UK data protection laws (GDPR). Other laboratories send their samples abroad, which can increase the likelihood of blood samples spoiling during transit.
When you perform your prenatal paternity test with AlphaBiolabs, your samples will be sent to our award-winning laboratory in Warrington. This allows us to get them to the laboratory quicker, and perform the test sooner.
How accurate is a prenatal paternity test?
Our prenatal paternity test results are 100% accurate based on the samples we receive. We test all of our exclusion results twice, so you can be confident that your result is completely accurate.
We also provide at least 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 isn’t always guaranteed. Although other testing companies may promise guaranteed results, this is not true. As a trusted and accredited UK laboratory, it is important for us to make you aware of this outcome.
In some cases, the mother’s blood sample may contain insufficient cell-free DNA (cfDNA) from the foetus. This can lead to an inconclusive result.
We are the only UK laboratory to offer a money-back guarantee
In the event of an inconclusive result, we offer an additional test free of charge 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 promise 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 payable due to the high cost of analysis.

Frequently Asked Questions
How does the prenatal paternity test work?
Our non-invasive prenatal DNA testing provides the most accurate way to determine paternity before birth. It uses a state-of-the-art process which combines the latest DNA technology and unique methods of preserving the baby’s DNA, which is naturally found in the mother’s bloodstream after 7 weeks into the pregnancy.
What exactly does non-invasive mean?
One of the best ways to explain non-invasive is to look at the opposite approach: an invasive DNA paternity test. The traditional invasive prenatal paternity tests require that cells be obtained from either the amniotic fluid or the placenta.
The non-invasive paternity test uses a simple blood sample from the mother and therefore does not require a needle to be inserted into the womb.
When is the earliest I can take the prenatal paternity test?
Non-invasive prenatal testing can be carried out as early as 7 weeks into the pregnancy. You can use our pregnancy calculator to work out how many weeks pregnant you are.
How safe is the test? What are the risks?
With our unique, non-invasive prenatal paternity test, there is no risk to the mother or baby.
How accurate is the DNA test?
This is the most advanced prenatal paternity test currently available. We provide at least 99% probability of paternity where the father is confirmed as being the biological father.
What are the chances of getting a conclusive result?
In the majority of cases, we provide at least 99% probability of paternity where the father is confirmed as being the biological father.
However, a conclusive result cannot always be guaranteed because of the scientific limitations of non-invasive prenatal paternity testing.
In the unlikely event of inconclusive results, we offer up to two additional tests free of charge (after the mother is at least at 9 weeks into the pregnancy) with newly collected samples. However, 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. This is considered an inconclusive result and we will therefore refund the cost of your prenatal paternity test.
What samples are required?
Two mouth swabs are needed from the alleged father and a blood sample from the mother.
Is a sample needed from the alleged father?
Yes. We need samples from both the mother and alleged father.
Can the samples be collected at different locations?
The samples do not need to be collected at the same location. However, the samples should be collected around the same time to avoid any delays and the risk of the blood samples haemolysing.
What are the options for sample collection?
The blood samples are time sensitive and need to be collected by a trained nurse, a phlebotomist, or an AlphaBiolabs fully trained sample collector. The mouth swabs also ideally need to be collected by an AlphaBiolabs sample collector. Both of these samples can be collected at the same time, or separately, at one of our nationwide Walk in Centres.
We can also arrange to have one of our trained sample collectors visit your home, or anywhere else convenient, to collect your samples. These two options ensure that the samples are collected correctly and are then safely returned to our laboratory for testing. Alternatively, you can choose to arrange your own blood sample and mouth swab collections. In this case, you will be responsible for returning the samples to the laboratory.
What if a re-collection is required?
If the blood or mouth swabs have insufficient DNA then an appointment can be arranged to recollect up to two additional samples. Please note that you will be responsible for the costs of these additional recollections. However, the additional tests themselves will be free of charge. If the testing is still unsuccessful after this time, results will not be possible and we will refund the cost of your prenatal paternity test.
When do I get my results?
Results can be made available in 4–7 working days depending on the level of service you choose.
Our express service can get your results back to you in just 4 working days (for an additional £200).
How much does the prenatal DNA test cost?
Results can be made available in 5-7 working days for £795. An express service to guarantee your results back in just 4 working days is also available for an additional £200.
A 6-month interest-free credit payment option is available, subject to status. Please call us on 0333 600 1300 to apply.
How do I order a prenatal DNA test?
You can order your test here and one of our Customer Services team will be in touch to arrange your sample collections.
Alternatively, you can email firstname.lastname@example.org or call Customer Services on 0333 600 1300. We can talk you through the process and outline the next steps.
What is included in the kit?
Our prenatal paternity testing kit includes full instructions, DNA swab packages, swab envelopes, blood tubes, a DNA test request form, and a return envelope.
Please note that needles are not included in the kit. If you book a sample collection appointment with us, we will provide the needles. Otherwise, needles should be provided by your chosen phlebotomist or other medical professional.
