Affordable and accurate paternity testing; answers for you.

Our “That DNA Company” brand is intended to be a value ‘no frills’ service which gives you a reasonable cost test, with the assurance that there is an accredited UK laboratory performing your work.

By using our own laboratories, we can offer you exceptional value for money and still with the same quality of processing and analysis that you should expect from such a sensitive purchase. You can rest assured that your samples will not be sent abroad.

Using DNA testing, we work out whether or not there is a possibility of an individual being the biological father of a particular child. This is also sometimes called a paternity test.

Each and every one of us is unique. This uniqueness comes from our genetic code, which we have inherited equally from our biological mother and biological father. The “That DNA Company” paternity test detects the presence of shared regions of this unique genetic code, which can in turn be used to determine if individuals are related.

We analyse your genetic code and the results are displayed as a series of coloured bands. We then look at these bands from both mother and alleged father to see if every band in the child is present in the parents. If so, there is a good chance that the child and parents are biologically related.

Please be aware that the “That DNA Company” DNA test is for personal information only. It cannot be used for legal purposes. If you wish to have a DNA test for use in court, to change a birth certificate or some other legal reason, then you will need an accredited (legal) DNA test. This is available from www.dadchecksilver.com, a service which is also part of Complement Genomics Ltd. For more information please call 0191 543 6434 or e-mail sales@dadchecksilver.com.

Please note that this service is for the general public only. Solicitors and social services should continue to use www.dadcheckgold.com and contact us on 0191 543 6334 or e-mail sales@dadcheckgold.com. Please note that we do not carry out forensic DNA testing (e.g. hair, semen) for the general public.

Our DNA testing services are not limited to paternity testing, we can also offer a wider range of other genetic testing services including, sibling (full, half or unrelated), avuncular (aunts/uncles) and grand-parentage tests. More information can be obtained by e-mailing sales@dadchecksilver.com or by calling us on 0191 543 6405 with your specific request. We are experts in DNA testing and genetic test design and can advise on any number of issues within this dynamic field.

There are no hidden costs and no hidden extras. The price includes the kit (swabs, consent forms, return postage paid envelope), all postage, the laboratory testing and the reporting.

We strongly recommend that the mother of the child is involved in the testing process and there is no reduction in the price if the mother is not tested.

If you lose, destroy or render the kit unusable, we will charge £12.50 for a replacement.

Some customers will require an extra kit or a report to be sent by post. There is a separate charge for either of these at £12.50 respectively and if you wish us to provide this, please call 0203 603 1189 after you have placed your order. Alternatively you may request we issue you a PayPal invoice.

Postage is included for extra kits and reports, except for overseas shipments, when we will discuss this with you.

Please carefully read our Terms and Conditions of sale, which indicate our refund policy.

Once you have placed your order, a personalised DNA testing kit will be sent to the address of your choosing. The kit will arrive in an opaque envelope and will include a consent form, one sterile mouth swab per donor, a pre-paid return postage envelope and a ‘Communicating with you’ sheet.

When you place your order you will be sent an e-mail with a login and a password. You may use this to track the progress of your case.

When your samples arrive at our laboratory, you will be sent another e-mail to confirm their receipt. When you log in, you will be able to see an estimated completion date, plus any messages we may have for you. If there is a delay for a re-test or some other issue, we will inform you by this route. For example, it may be that in the case of a test where the alleged father has given consent and the mother is not participating, that we ask to see evidence of Parental Responsibility. This may require you to show us an appropriate marriage or birth certificate.

The estimated completion date will also be found at this login and may be updated from time to time and is non-binding. It will generally be about 5 working days from receipt of all of the fully consented samples into our laboratory. Your results will generally be uploaded after 4pm on the designated completion day.

When your results have been uploaded, you will be sent an e-mail to inform you of the availability of the results and to remind you to log in.

Analysing your genetic code using a DNA test is the only accurate way of determining whether or not a biological relationship exists between individuals.

The “That DNA Company” paternity test proves with 100% certainty if a man is not the alleged father of a child.

Conversely, a “That DNA Company” paternity test proves that a tested man is the alleged father of a child with at least 99.99% certainty (if the mother is involved in the testing process).

Please note that this figure may be reduced if the mother of the tested child does not participate in the test.

All people providing a sample for a “That DNA Company” DNA test must give their consent for the test by signing the personalised consent form provided in the sampling kit.

We will not process samples for any paternity test unless we have the signed (written) consent of each of the adult participants and if a child under 16 is involved, a person with Parental Responsibility for the child (or children) taking part.

You should be aware that it is a serious offence, punishable by imprisonment, to personate another body for the purpose of providing a bodily sample (e.g. for a DNA test) or to proffer the wrong child for that purpose.

It is also a criminal offence to have in possession bodily material for which a DNA testing is intended, without appropriate (qualifying) consent. If the consent form has not be signed properly or appropriately, we will not proceed with the test.

If you wish to provide a sample for a That DNA Company paternity test you must be absolutely sure that it is your sample and that you have signed the consent form which gives us permission to carry out the test.

Please note however that an individual may withdraw their consent at any time during the testing process but not after the Test Report has been issued.

Consideration must also be given to older children e.g. 10+years and under the age of 16 years as they are likely to be able to understand the nature and possible consequences of a DNA test. We strongly recommend that the person with parental responsibility discusses the DNA test with the child and takes their views into account.

From the time we receive the samples, the test will take approximately 4 working days if you have ordered the standard test and approximately 2 working days if you have ordered the accelerated test. We will not give progress reports until the Paternity Report is ready. This Paternity Report will only be sent to the person ordering the DNA test and we will not discuss the case with any other person unless we have written permission to do so.

You will receive an e-mail when the Paternity Report has been uploaded and this will generally be after 4pm on the expected day of delivery. Please do not call for results before this time, as staff will not be able to update you until the report has been signed off by the Quality Manager.

If we have any issues with the data (such as the need to repeat the sampling), you will receive an e-mail to keep you updated.

Parental Responsibility (PR) means that the person concerned has all of the rights, duties, powers, responsibilities and authority that a parent of a child has by law (as defined in the Children Act 1989).

Where a child’s parents were married to each other at the time of the child’s birth, each parent will have Parental Responsibility for the child.

However, if a child’s parents are not married to each other, the mother shall automatically have Parental Responsibility over the child. Where the parents are not married to each other, the alleged father will acquire Parental Responsibility if he acts with the mother to have his name recorded on the child’s birth registration after 1st December 2003.

An unmarried alleged father will not be able to claim Parental Responsibility unless he acquires it by:

  • Obtaining a court order.
  • Registering a legally written agreement subject to the mother’s consent.
  • Marriage to the child’s mother.
  • Being granted a residence order.
  • Having his name on the child’s birth certificate (for births registered after December 2003).

People other than parents may acquire Parental Responsibility by appointment as a guardian or by an order of the court.

The “That DNA Company” paternity test is conclusive if we can test all three of the child, mother and alleged father.A test without a sample from the mother will not provide the same degree of certainty as a test with samples from both parents.

No. Our samples are taken by gently rubbing a soft cotton swab around the inside of the mouth. Full instructions of how to take the samples are included in the “That DNA Company” sample collection kit and on our website.

The procedure is simple and painless and can be used on young children and newborn babies.

If you are unsure and would like some guidance on the DNA sampling process then please watch our video.

As this is a home testing kit, you must be sure of the identity of the persons participating and we expect you to warrant those identities. You should be aware that it is a serious offence, punishable by imprisonment, to personate another body for the purpose of providing a bodily sample (e.g. for a DNA test) or to proffer the wrong child for that purpose.

Please note that it is NOT necessary for all individuals who are giving a sample to all be present together at the same sampling venue at the same time or indeed to be in the same place for sampling. However, at the time of sampling, a child who is under sixteen MUST be accompanied by the person with Parental Responsibility, as indicated on the consent form.

On rare occasions we are unable to obtain any DNA profile, a complete DNA profile, or there may be issues with contamination/mixed profiles. The actions we will take are as follows:

1) Discoloured (e.g. due to food/nicotine) swabs or mouldy swabs (due to the long time taken to return them to us) will not be used. We will inform you of this point via e-mail and offer you a replacement kit for a charge of £12.50.

2) If we have started the laboratory work and find an issue such as no DNA on the swab, mixed profiles or adulteration, then we will inform you of this point and offer re-sampling for a charge of £44. If we do not gain enough DNA from one swab to complete the test, we will conduct the work once more, then process the second swab before taking the decision to re-sample. This can cause a delay to your expected completion date.

The original report is uploaded as a .pdf to a secure web-link which is provided to the person who ordered the test. The reports are in a standardised format, which complies with relevant legislation* and either excludes the alleged father or provides evidence that he is indeed the tested child’s biological parent.

If the “That DNA Company” paternity test is negative (that is, the tested man is not the child’s biological alleged father), the report will say:

‘Based on the analysis of 23 independent autosomal DNA markers, Mr John Smith has been excluded as the biological alleged father of Teresa Green because greater than two of Mr John Smith’s DNA components are absent from the DNA profile of Teresa Green. In summary, Mr John Smith is not the biological alleged father of the child, Teresa Green’.

If the “That DNA Company” paternity test is positive (that is, the tested man is likely to be the alleged father), the report will say:

‘The probability of paternity is 99.99xxx% (assuming equal prior odds) based on the analysis of 23 independent DNA markers. Hence the alleged father, Mr John Smith, cannot be excluded as the biological alleged father of Teresa Green.
The DNA results are ‘X’** times more likely if Mr John Smith rather than an unrelated male is the biological father of Teresa Green. In summary it is more than 99% likely that the alleged father Mr John Smith, is the biological father of Teresa Green’.

We do not issue the original data (DNA profiles), since interpretation of these data is highly complex and requires a trained operative.

* The Family Law Reform Act 1969 as amended by The Family Law Reform Act 1987 and The Family Law Reform Act 1987 (commencement No.3) order 2001 and The Children Act 1989.

**The value of ‘X’ will vary between cases but will usually exceed 50,000.

We shall only correspond with the person who has ordered the DNA test (the nominated person), unless we receive their permission to enter into correspondence with those other parties involved in the paternity testing case. We will only discuss the case if we are confident we are talking to the nominated person. Please expect that we will ask you for your case number and certain other details of the case.

Your results will be uploaded as a .pdf onto our secure server and you may access this with the login and password you will have been given at the time of ordering. Any further copies of the report such as by first class mail will incur a charge of £12.50.

After we have sent out your DNA test reports, we will store your DNA samples for three months and after this period, they are incinerated.

All associated paternity test paperwork and records are kept for one year and then destroyed. We are registered under the 1998 Data Protection Act. You can find more information about how we protect your privacy by reading our privacy policy.

“That DNA Company” uses all reasonable precautions to make sure that samples received for testing cannot be mixed up. Our team of highly skilled and qualified scientists adhere to strict laboratory requirements of internationally recognised quality standard, ISO 17025 (an accreditation for testing and calibration laboratories).

Included in this is the requirement for all work to be witnessed and double-checked by a second competent member of scientific staff. We have every confidence in our team and supporting Quality Management System .

Shortly after you have completed your online order, we start to produce a DNA sampling kit which is tailored specifically for your case, with named and numbered swabs being issued to the contracting party. This is the point of Commencement of our Service to you. If you order a kit and immediately wish to cancel (i.e. before we have started to produce a sampling kit), then we will issue a refund. We do not generally issue refunds after the kit has been produced and sent to you, as our service to you has started. However, we may grant a partial refund (which is solely at the discretion of the Management) if we have not yet started the laboratory work. Please note that before ordering, we expect you to ensure that all participants of the test have agreed to it and have expressed their willingness to consent to it.

If you are from the general public and have more complex DNA testing needs, then we would like to direct you to our sister service which can accommodate complex requests. This might be a private accredited (legal) DNA test, immigration (Home Office) DNA test, a maternity DNA test (generally required for immigration applications), DNA tests on deceased persons (forensic DNA testing), surrogacy DNA tests, sibling (full, half or not related) DNA tests, sperm donor testing (alleged father and child) or grand parentage DNA testing. Also if one of the participants lives far away from you/you don’t want contact or overseas, that is a separate DNA testing kit is required, then please contact us on 0191 543 6434, e-mail sales@dadchecksilver.com or go to www.dadchecksilver.com.

If you have any questions, we will be happy to help.

If you have a solicitor (or social services are involved) and they are dealing with your DNA testing case, then please direct them to our service for professionals, which is: www.dadcheckgold.com. You can ask them to call 0191 543 6334 or e-mail sales@dadcheckgold.com.

Our laboratories are recognised by the Ministry of Justice for legal DNA testing and we hold the international accreditation standard, BS EN ISO 17025 for testing laboratories.

Sibling DNA testing is definitely possible and we do conduct quite a lot of this type of work. Essentially, we are asking if two individuals are related as full siblings, as half siblings or are not related at all. Twins are essentially a special type of sibling DNA test and we can certainly test the DNA of twins to determine if they are identical or non identical. However, please go to our sister service, dadchecksilver.com which offers DNA tests for more complex needs, such as this. Please contact us on 0191 543 6434, e-mail sales@dadchecksilver.com or go to dadchecksilver.com

It will not. A DNA test for human identity testing is completely different from the COVID-19 test and one does not affect the other.

The sampling process for a DNA test is the same as before the crisis – we would just ask you to take a few extra precautions. With thatdnacompany.com we send out one kit per case. If the participants of the DNA test do not live in the same household and you will not be in physical contact with them, we suggest you call us to order a second kit which will be sent to their address. There is a modest charge of £12.50 for this, but it does mean we can still conduct the DNA test with minimal risk.

The government’s advice is updated regularly and please follow these recommendations, especially with regard to social distancing and shielding. You can spread the virus even if you don’t have symptoms.

We have a solution for all your DNA testing needs

If you would like a sibling, grandparentage or aunt/uncle DNA test, then we can do that too!

Please call to discuss your case with one of our experienced and helpful case managers.

DNA Testing Services

Our standard DNA test takes around 4 days or you can pay a little bit extra for a 2 day turnaround (from the time we receive all of the properly consented DNA test samples into our laboratory). Your DNA test results will be uploaded to our secure website (and we will provide you with a password).

That DNA Company: Extended Services


Do you require a DNA test for legal purposes? (An accredited test)

This is for changing the name on a birth certificate at the Registrars office, family court proceedings, inheritance disputes, liaison with either the Child Support Agency (CSA) or the immigration authorities. As this is a different level of service, please click here to contact the laboratory by e-mail.


Do you require a DNA test to determine other relationships?

As well as testing for paternity (proof of fatherhood), we can also test for other biological relationships such as sibship (full, half or unrelated), grandparentage and avuncular (aunts/uncles). Again, this is a different service and you will need to discuss your case with a member of our team. Please click here to e-mail our laboratory.
