Can I do a paternity test without the mother?
DDC always recommends that the mother contribute her DNA sample to a paternity test. However, although her participation is recommended, it’s not required. If you are trying to decide whether or not mom should be part of testing, here are some sample scenarios that can help you make the best choice for your unique situation.
A Mother’s Participation can Help Strengthen Paternity Results
In the majority of cases, a paternity question can be answered with only the possible father’s DNA and the child’s But in some relatively rare instances, the mother’s DNA can help strengthen results.
A child gets 50% of their DNA from the biological mother and 50% from the biological father. Therefore, the child must match both parents at every single DNA marker. If the man being tested has only one mismatch with the child, it may be due to a natural mutation and may not necessarily mean he’s not the biological father. When the mother’s DNA is included in the test, this question can be resolved and conclusive results given.
If there are two possible fathers for a child and those fathers are biologically related (brothers, father/son, etc.), then it’s essential to include the mother’s DNA sample in order to strengthen results.
A Mother Who Participates Gets Guaranteed Access to Results
As a top DNA lab maintaining the highest levels of accreditation, DDC maintains a strict policy of confidentiality. Results can only be released to participants in the test, to their legal representatives (such as lawyers), or to the tested child’s legal guardian, if that child is a minor. Therefore, to guarantee quick access to test results, it’s a great idea for the mother to just submit her DNA too, even if it ends up not being needed to strengthen results.
If You’re Doing a Legal, Chain-of-Custody Paternity Test
In many cases, courts who order a paternity test require the mother to participate. Court-ordered tests are also called legal or chain-of-custody tests, wherein DNA collection and sample-submission to the lab are supervised by an approved witness.
If the court requires the mother to participate in testing, then the test cannot be performed without her.
