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.
Example 1:
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.
Example 2:
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.






The father of my child is denying my son because he looks like me what do I need to do to get a DNA test so I can prove he is the father.
Hi, Tenise. Do you want to know for informational purposes only? Do you anticipate needing to use the report in court for child support? I suggest you contact our experts directly to see what type of test might be best for your situation: 800-681-7162 (M-F, 8 AM to 8 PM Eastern).
Hi, my daughter and her father recently got a DNA test done. I am very certain he is her biological father. I am the mother and have been requested to get a swab done as well. Does this mean he is not the father? Should I be worrying so much? I am stressed out because it doesnt make any sense to me.
Hi, Taylor. You can ask those doing the testing why you were requested to contribute your DNA as well. Without seeing the data I can’t tell you for sure, but it’s most likely because the analysts need your DNA in order to strengthen results.
Hi my husband does not think it possible he could have fathered a young man birthed by a woman my husband only saw twice. They may be related possible cousins. Could that make him look like the father in a dna test? Also she may have actually been with his brother. How accurate would dna testing be for only father child?
Hi, Candy. A cousin relationship doesn’t matter. Ideally, your husband AND his brother would both do the test, along with the mother of the child. If that’s not possible, your husband could test by himself, as long as the lab is made aware ahead of time that another possible father is brother to the man being tested. This way, the lab can take this information into account when performing the analysis and test additional markers if necessary. The mother of the child should also participate in this test. Good luck!
My son is 23 but he refuses to do a swab what other method i can used
Hi, Edwin. Your son is an adult and must provide his consent for testing. If he refuses to do a swab, then he’s refusing to test.
When we get the results my baby boy was so stress out he couldn’t eat anything ,he keeps asking question why this is happening to him I’m very stressed that could affect him on his school work
Hello I have 2 children boy and the girl and i said yes because I know that they are his children but when the results come back the boy say they don’t match and the girl is a match is it’s possible
Hi, Yoliswa. It would appear that your children have a different biological father, from what you said. Yes, it’s possible.
