Paternity tests can be performed without the Mothers DNA when it is not possible for her to be included or involved in the test. As long as the appropriate consent can be obtained, then the Paternity test can be performed with the alleged fathers DNA sample and the DNA samples of the children involved.
However, by involving the biological mother of the children, the paternity test result is increased in accuracy.
This is not just true for DNA paternity testing. Including the biological mothers DNA in any form of DNA test strengthens DNA test results. Whenever it is possible, the biological mother should provide a DNA sample as a test participant. In paternity tests and most other forms of DNA test, the mothers sample will be processed for free in the DNA test. Free DNA testing of the mothers sample is provided due to the increased accuracy it provides. It is hoped that providing free DNA testing for the mother in a case will encourage these samples to be used in Paternity tests. Testing the mother's DNA increases the likelihood of a conclusive result for any DNA test - including DNA tests for siblings, or grandparents.
If the circumstances surrounding a DNA test mean that test participants want to attend appointments separately, then this can easily be arranged at our DNA testing clinics.
Legal DNA Paternity cases must include the mothers DNA sample, unless there are exceptional circumstances for her absence from the paternity test, or when the paternity test has been ordered to go ahead by the court.
