Court Approved DNA Testing

DNA testing is a scientific process which can positively identify relationships between people. Most commonly it is used to establish if a man is the true biological father of a child. DNA paternity testing is also often referred to simply as a DNA test, a paternity test or DNA testing. Cellmark has been providing a confidential, conclusive, court approved DNA testing service for more than three decades.

How do I register for testing?

You can complete your registration using our online service or by calling Cellmark's Customer Services team on 0800 036 2522 Cellmark will assist with arranging a convenient time for an appointment for the DNA samples to be taken using:

  1. Our dedicated sampling service
  2. Your own GP
  3. A GP from the list we supply

If you use a GP you should allow at least two days for Cellmark to deliver the DNA sampling kit to the chosen doctor(s). Each person being sampled will also need two passport-sized photographs or photo ID with them to confirm their identity. However, if you elect to use Cellmark's sampling service they will have kits and forms and no photographs are required as they will be taken digitally.

Next Day testing - as standard

If all your samples reach us by 10am we can get the test report to you by the end of the next working day at no extra cost.

Thanks to the advances in testing technology, Cellmark is able to deliver Next Day results using the most conclusive 24 marker genetic analysis system. Our 'Next Day DNA' service applies to all of the relationship types we test for, including paternity, maternity, sibling, grandparent and avuncular (Aunt/Uncle) tests.

Important Considerations

When you choose Cellmark you can be sure your test will be carried out with the care, accuracy and precision it deserves. Every test is carried out twice using the latest DNA profiling technology to provide certainty, with accurate, high quality and reliable relationship analysis.


 Accredited UK Laboratories

The Ministry of Justice maintains a short list of companies who are accredited to carry out parentage tests. Being accredited by the Ministry of Justice means that Cellmark abides by the standards originally set down by the Dept. of Health's voluntary code of Practice and the subsequent Human Genetics Commission's 'Common Framework of Principles' and the Human Tissue Act.

All reputable DNA testing services should abide by the Codes of Practice set out in these documents. Cellmark is also certified to International Quality Standards ISO 17025 (for laboratory testing services) and ISO 27001 (for the robustness of our information security).

 Independent Sampling

Samplers must not be related to the sample giver, nor have any financial or personal interest in the outcome of the test. This can be either a medically qualified practitioner or an individual trained by the testing organisation.

Cellmark offers a nationwide sampling service and provides all samplers with clear instructions. In addition to providing details of how the sample should be collected, these instructions cover the need to take into account the views of the child where appropriate, the wider welfare concerns of the child, and the need to ensure that proper measures have been taken to obtain legal consent.

 Legal Consent

Under the Human Tissue Act 2004, consent is legally required for a biological sample to be DNA tested to determine paternity or any other relationship. Written, informed consent must be provided for each adult sample and for each sample taken from a child. Failure to ensure this can open yourself up to the offence of "DNA theft" which is punishable by a prison sentence of up to 3 years and/or a fine of £3,000.

Someone with Parental Responsibility for a child must provide written consent. An unmarried father who is not registered on the birth certificate does not have parental responsibility and therefore cannot give consent for the child to be tested. Without the mother's consent to testing he would have to go to court to seek a Parental Responsibility Order to progress the issue further


 Chain of Custody

As a general guide, a court will seek assurances that a paternity test, the findings of which will be used as evidence, has been conducted properly with a clear audit trail.  This is required to show that the correct people provided the samples; that those samples reached the testing laboratory; that the testing laboratory was competent to carry out the tests; and that the results relating to the samples then reached the court.

Samples are sent to Cellmark’s Abingdon UK laboratory in tamper evident bags. On receipt, the bag is examined to ensure that the samples have arrived in tact and the details on both the documents and samples have been completed correctly. Once all the samples that are to be tested have been received and have passed our checks they are passed to the Laboratory for DNA testing.

How does a DNA test work?

A simple mouth swab is used to collect a sample from an individuals cheek. The samples are then sent to our laboratory where a small section is taken by a scientist carrying out your DNA test. DNA is extracted from the sample and a special enzyme is used to copy the genetic code at the relevant regions in the DNA. 

Testing works by detecting certain parts or ‘markers’ in the DNA molecule that are known to vary greatly between unrelated people. Our tests compare the DNA at a number of these markers to determine if people are related. The process is called Short Tandem Repeat (STR) profiling. STR profiling is a very sensitive DNA testing procedure. 

Each DNA profile is analysed using the latest specialised software. The software will assign a designation to the DNA markers at each test. The DNA profile will consist of a minimum of 22 autosomal DNA tests and 2 gender indicative tests. The DNA profiles are assessed for quality by our experienced reporting scientists. If a complete DNA profile is obtained i.e. a result is observed at each test, then the sample has passed. 

DNA profiles from the individuals in a case are compared with each other to identify any matching DNA markers between them. A statistical analysis is carried out to determine the likelihood of a biological relationship such as paternity. The analysis involves determining the number of matching DNA markers and their frequency in the population. The details of the individuals tested and the results of their DNA test are entered onto the final DNA report. 

How are my results reported?

Cellmark can provide the DNA report as either a paper copy which is prepared on embossed paper or an electronic copy which can be sent by e-mail.

Please consider that choosing to have a 'peace of mind' or 'curiosity' DNA test may not be the cheapest option - if you subsequently end up having to go to court to resolve the issue you will need to undergo another test - this time a court approved test - so careful consideration of your options is sensible. We recommend that you talk to a third party such as the Citizens Advice Bureau, your GP or a family friend.
