DNA Relationship Testing


If your samples reach us by 10am we can get the test report to you by the end of the next working day!

DNA testing is a complex 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. Thanks to the advances in DNA testing technology Cellmark delivers Next Day results as standard using the most conclusive 24 marker genetic analysis system across our range of DNA relationship testing services.  This includes DNA tests for Paternity, Maternity, Sibling, Avuncular (uncle or aunt), Grandparentage and relationship tests for Immigration applications.

  Court approved DNA testing


The Ministry of Justice maintains a short list of companies who are accredited by the Ministry of Justice to carry out parentage tests as directed by the civil courts in England and Wales under section 20 of the Family Law Reform Act 1969.

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 ISO17025 (for laboratory testing services) and ISO27001 (for the robustness of our information security).


I have been using a variety of different firms for DNA and drug and alcohol testing for years as a solicitor for the local authority.  Before I found you, none of the others have the approach with all staff members that I was seeking, or the speed at which you respond to queries, issues etc.. before I came across Cellmark. Thank you.

Independent advice and guidance

The decision to have a paternity test is one faced by thousands of people every year, often in complicated emotional circumstances. Cellmark is committed to ensuring that all parties have access to independent advice and guidance and the following links may help you in making your decision to proceed (or not to proceed) with testing.

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 (or see list below).
