DNA test results and reports

If you would like to know about DNA paternity testing, including the reasons for paternity testing and the types of DNA paternity tests that are available, the information in our DNA testing guide will interest you.

Your DNA test results

Once your samples have reached the laboratory the DNA testing process can begin. You should expect to receive a report on your DNA test results within 3-5 working days.


DNA test reports from ethical companies will include a covering letter which confirms their data protection policy :-


"Please note that unless you instruct us otherwise we will destroy the samples three months after the date of this report and any paper and computer records relating to the test will be destroyed after twelve months. It is important that you keep your copy of this report safe." 


The wording of the report needs to comply with the Family Law Reform Act 1969 so that DNA Paternity Test reports can be accepted and used in court proceedings. An ethical and accredited tester will supply reports to the appropriate standards.

The paternity test report will either exclude a man from paternity or will provide conclusive evidence that he is the father of the child.  If for example a child (Mary Jones*), her mother and her alleged father (James Smith) were tested, the report would be worded as follows:

A positive paternity result


Probability of paternity 99.9999%

Combined paternity index of 1,000,000 to 1

The putative father, James Smith is not excluded from the paternity of Mary Jones. The results obtained are consistent with James Smith being the biological father of Mary Jones and are one million times** more likely if James Smith is the father of Mary Jones than if they are unrelated.

The probability of paternity given the DNA evidence is at least 99.9999% compared to an untested random man of the UK population.

A negative paternity result


The DNA tests exclude paternity. James Smith cannot be the father of Mary Jones as he lacks the genetic markers that must have been inherited by the child from the biological father.
