Next Day results

If all of your DNA samples arrive at our UK laboratory before 10am we aim to send the paternity test result to you by the end of the next working day by email.

Important Information

A DNA paternity test is a scientific way to determine if a man is the true biological father of a child. A simple mouth swab is used to collect a small DNA sample from the alleged father and from the child and the samples are then sent to Cellmark’s specialist DNA laboratory for testing and analysis.

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 man from paternity with 100% certainty or will indicate a paternal relationship with a very high level of confidence - usually in excess of 99.99%. When carrying out a paternity test, including a sample from the mother (as well as from the child and alleged father) will always provide a more conclusive result.

Please note that DNA at Home’s paternity test is what is termed a ‘curiosity test’ - this means that the results will not be accepted in UK courts, nor by the Child Maintenance service. If you are disputing paternity and require a test for legal purposes then please visit our legal DNA paternity testing site -

As with all of our DNA relationship testing services we offer a Next Day DNA service 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.

DNA relationship testing can be a life changing event and we would urge that before ordering a test you think carefully about the potential outcomes and have considered if testing will be in the best interests of the child(ren) involved.
