DNA Testing

We have been providing DNA Testing in the UK since 2005. Our DNA Clinics brand is one of the most trusted in the country, with kits such as the Paternity Test sold through Boots. As a result, our combination of DNA Clinics and test kits provides you with unrivalled choice for your DNA test.

The DNA testing process is simple. First, we will help you choose the right test for your situation, for example, a Paternity Test. Then, we will advise you on whether an appointment or self-collection kit is the most suitable. Next, once we have your samples, testing is undertaken by a UKAS 17025 accredited laboratory. Finally, we will send you your results in full compliance with GDPR requirements.

How does DNA Testing work?

This short video provides information on how DNA testing works. Also, you can read how it works here:

DNA stands for deoxyribonucleic acid. It is the genetic material found inside a cell. Also, DNA is very fine and tightly coiled into structures called Chromosomes. Each cell contains 46 chromosomes.

22 of these are pairs which are almost identical. The remaining two are the X and Y chromosomes which determine the sex of an individual. Women have two X chromosomes and men have one X and one Y.

If the DNA was taken from a single cell and unwound, it would stretch to a whole meter in length. It is estimated, that if this was done for all the DNA, in all the cells of one body, there would be enough DNA to stretch all the way to the moon and back – TWICE! Amazing if you consider this molecule is too small to be seen by the naked eye.

Your DNA is unique

Your DNA is unique to you, just like a fingerprint. The only people in the world who share identical DNA are identical twins, because they began life as a single egg that split in their mother’s womb. The fact that they share identical DNA is the reason they look identical.

Small portions of the DNA are called Alleles. When a scientist looks at a piece of DNA, they can analyse the alleles they find. We identify the alleles and give them a unique number. These numbers represent a person’s DNA profile.

At each location on the DNA molecule, a person has two alleles. Therefore, when looking at a person’s DNA profile, you will see two numbers for each part of the DNA analysed.


How do we analyse DNA for relationship tests?

At the point of conception, a child’s DNA is formed. Half of the DNA comes from the mother (in the egg) and half comes from the father (in the sperm). Therefore, when we look at a child’s DNA profile, one of the numbers at each of the locations, will match one of the numbers at the same location for each biological parent.

In other words, half the alleles (the numbers) will match exactly to the DNA of the biological mother and the other half will match exactly to the biological father.

When testing other relationships such as potential siblings, we would not expect a match at all locations. This test works on the fact that biologically related individuals will have more DNA in common than those that are unrelated.

When you get your DNA test results, we explain all of this in your report package. Our team is also on hand to answer any questions you might have.


How is DNA Collected?

An identical copy of a person’s DNA is kept inside all the cells of that person’s body. Therefore, the DNA inside a blood sample is identical to the DNA inside a cheek cell. By rubbing a mouth swab on the inside of the cheek, we obtain cells without the need for painful blood samples being taken. This is much easier for the clients and especially for any young children involved.

The DNA from these cheek cells is easily isolated and is then ready for testing. This process is just as accurate as using blood samples. We can use forensic samples as a source of DNA, but only in certain circumstances.

Check out this short video that demonstrates how DNA mouth swabs should be collected.


What DNA Tests are available?

  • A Paternity DNA Test is used to establish the biological father of a child. Also, Paternity tests are available for both legal and peace of mind purposes.
  • A Maternity DNA Test is used to establish the biological mother of a child. Also, legal and peace of mind options are available for this test.
  • The Sibling DNA Test establishes a biological relationship between potential siblings. Also, this includes whether they could be full or half siblings, or unrelated.
  • The Grandparent DNA Test can determine the biological grandparents of a child. Also, we can perform single or duo grandparent testing to improve accuracy.
  • Twin DNA Testing, or Zygosity testing, is a type of DNA test to determine if twins are identical or not.
  • Uncle DNA Relationship Testing establishes a biological relationship between a potential uncle and niece/nephew.
  • Aunt Relationship DNA Testing can determine a possible biological relationship between an aunt and a niece/nephew.


Why choose DNA Clinics for your DNA Test?

Since 2005, DNA Clinics have been providing clinical services in the UK. During this time, the service has evolved to meet the precise needs of the test participants. As a result, we provide one of the most trusted genetic relationship services in the country. So much so that we are the only company to sell three test kits with Boots. This includes the Paternity test, Sibling and Grandparent Tests.


A dedicated Case Manager throughout the process

We will help you choose the right DNA test that will provide the answers you need. Your Case Manager is on hand to provide support and advice during and after your test. Also, our Case Managers all have a medical science background. As a result, we can assure you of the best possible advice and answer any technical questions you may have.


Choice of legal or personal information DNA Tests

Our accredited *Legal DNA Testing service is available for a range of purposes. This includes immigration, child custody / maintenance and disputed Wills. Or we can offer peace of mind DNA tests for personal use only. This is a convenient and inexpensive option if a test is not required for legal purposes.

*Except section 20 court directed cases.


Wide range of collection options including DNA Clinics and self-collection kits

We are the only company providing clinic-based appointments for peace of mind DNA tests. This provides a clinical and professional environment. As a result, you can feel confident about the collection of your DNA samples. Alternatively, our home DNA kits are a quick and convenient way for you to collect your own samples. They are easy to use and require only painless mouth swabs. Home DNA testing kits can be ordered on-line here. Also, you can buy the official DNA Clinics Boots Tests on-line from Boots.com


Local DNA Clinics and mobile sample collectors throughout the UK

For your convenience, we have a vast network of local DNA Clinics throughout the UK. As a result, we can provide appointments for you within easy travelling distance. Or, we can arrange for a mobile sample collector to visit you at home or another convenient location. Search here for your nearest DNA Clinic or mobile collection service.


Transparent DNA Test prices

All prices include the following as standard:

  • Appointment co-ordination
  • Case management and administration
  • Sample collection
  • ISO 17025 Laboratory analysis
  • Secure results package by email

Please visit our dedicated DNA Clinics website for an example of the costs.


The most accurate DNA tests available

We analyse 24 DNA locations as standard for paternity DNA tests. Other testing companies will only analyse 16 as standard. This makes their tests less accurate and vulnerable to inconclusive results. As an example, we provide non-legal paternity testing, analysing 24 DNA locations. The Paternity Test costs from only £99 for 3 test participants – alleged father, mother and child.


ISO 17025 Accredited Laboratories

DNA testing is undertaken by a UKAS ISO/IEC 17015 accredited laboratory. This ensures that all testing follows strict chain of custody and laboratory standards. Importantly, all testing takes place in a UK laboratory.


Fast DNA test results

We provide all results within 3-4 working days from receipt of your samples at the laboratory. Only the more complex DNA tests can take longer due to the nature of the analysis.


Easy to understand results package

Our comprehensive test results package is easy to understand. We explain your results in simple terms. Also, we include information about the science behind the tests.

For Legal DNA testing, we provide photographic evidence with every results package. We are one of the only providers to do this. So, you do not have to request the photographic identification incurring extra cost.


Ongoing support

We commit to provide ethical testing services. As a result, post-test counselling services are available at selected DNA Clinics. We understand the anxiety and emotion involved in the process. In certain circumstances, there may be a need for support depending on the results. This extra service will incur other charges on top of the prices advertised.
