Legal DNA Maternity Testing

In legal DNA testing the most common form of testing is to identify the potential father of a child - but that isn't always the case. There are occasions where the requirement is to question whether an individual is the biological mother of a child.

What is a DNA maternity test?

A maternity test can be used where a child has been adopted and as an adult has sought to find their birth mother – once re-united testing may be undertaken so that their true biological relationship can be confirmed.  Maternity testing is also sometimes used to confirm the biological links to a child conceived by in vitro fertilisation. 

How do I register for maternity testing?

You can complete your DNA testing registration using our online registration service or if you'd prefer 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. 

How accurate is a DNA maternity test?

In the laboratory our scientists test the DNA samples with 24 ‘markers’ (for more information see our FAQs) to analyse the relationship of the people being tested. This produces extremely accurate results which will either exclude the woman from maternity with 100% certainty, or will confirm a close biological relationship.  Maternity is usually indicated with a very high level of confidence in excess of 99.99%.   If it is possible, including a sample from the child’s biological father is recommended as this will ensure that we can report the most conclusive statistical result.

Next Day Maternity testing

As with all of our DNA relationship testing services we offer a Next Day DNA service, as standard at no extra cost. This means that if all the DNA samples for your test arrive at our UK laboratory before 10am, we aim to send the test result to you by the end of the next working day by email.
