How to Conduct a Paternity Test without Involving the Father

How to Conduct a Paternity Test without Involving the Father post thumbnail image

A paternity dna test may be impossible following certain situations. A good example is in the event that the biological father has already passed away. That may not be why the involved party isn’t in a position to participate in the same. Other reasons may be the distance or simply being unreachable. In other cases, the reason may be as simple as the father refusing to participate. Where does that leave you? As much as it complicates the issue, it is important to note that all is not lost despite the father not being in the picture. PaternityUSA provides cheap home dna testing, if you have some family reconstruction tests that can help under such circumstances. Let’s discuss them in detail.

  1. Sibling DNA Test

As the name suggests, a sibling dna test involves brothers and sisters. For it to work, one of the kids must have been proven to be the biological child of the alleged father. Once that is established, the next step would be to test the dna samples of the known children with those in question. It is important to understand that both half and full siblings can be used when conducting this paternity test. Nevertheless, the relationship must be stated before the tests. That’s because the tests need to be done differently in either case.

  1. Grandparent DNA Test

On the other hand, a grandparent dna test involves the parents of the child’s biological parents. The test includes different parties, including the child, mother, and grandparents. Experts believe this method only comes second to the actual paternity test, including the biological father and mother. Its efficiency is at its best if both the grandmother and grandfather participate. However, if that’s impossible, for example, if only one of the grandparents is available, it is still okay to do the test. Even a single grandparent is enough to establish the probability of a biological relationship between their son and the child in question.

  1. Avuncular dna test

When the father and grandparents aren’t available for paternity testing, an avuncular dna test can still do the trick. It involves an uncle or aunt and their nephew or niece. When conducting this test, the aim isn’t usually about determining whether the child in question is related to the alleged father. On the contrary, it shows whether the aunt or uncle shares the niece or nephew relationship with the child. It has been a life-saver in situations where neither the parents nor the grandparents were available for the dna test.

Nevertheless, only carry it out with the full sibling of the alleged biological father. It could be a brother or sister but not a half-sibling. After all, going for a half-sister or half-brother can lead to the deduction of the wrong conclusion. In other cases, the results you get make it hard to come up with a decision.


From the above discussion, the mother or father doesn’t need to be available for a paternity test. Other parties can help, including siblings, aunts, uncles, and grandparents. Sometimes, full siblings can work, but only a full sibling will give the correct conclusion in other cases.
