Is Paternity Testing without the Father Possible?
There are many reasons why a possible father may not be available for DNA testing, and there are ways to determine paternity without him. Testing for paternity without the father requires the participation of some of the father’s immediate family members such as his parents, siblings, or other known children and, as always, it is helpful to include the child’s biological mother in the DNA test as well.

Family-reconstruction DNA tests can be used to determine paternity but usually do not produce test results that are as conclusive as a paternity test.
Bottom line: Test with the father if you are able to! Your results will likely be more conclusive and your test more cost-effective.
In a paternity test, the DNA of the father, child and child’s biological mother (optional) are evaluated to determine if the alleged father is indeed the child’s father. When the father is unavailable for testing, other paternal family members’ DNA along with the child and the child’s biological mothers’ can help to determine paternity. Below you will find several possible family DNA tests for finding paternity without the father.
Grandparentage DNA test for paternity
The best DNA testing option to determine paternity without the father is using the DNA of the father’s parents, or the child’s paternal grandparents. In addition, the child needs to submit a DNA sample and the child’s biological mother should do likewise. This test gives the most conclusive results out of any family-reconstruction DNA test in helping to determine paternity. Although you may be able to discover paternity using only one grandparent’s DNA, results are more conclusive with both.
Avuncular DNA test for paternity
Another option for finding the paternity of a child without the father is using the DNA of a full sibling or siblings of the father; or in other words, the child’s aunt(s) or uncle(s). Like the grandparentage test, the child’s and child’s biological mother’s DNA are necessary for getting the most conclusive test results.
Siblingship DNA test for paternity
Your final option is a siblingship test. This test requires the DNA of another known child of the possible father. In this case, the mother’s DNA greatly helps with receiving conclusive results.
If you find yourself needing to find the paternity of a child, but the father isn’t available, you have other options. Other family members’ DNA of the alleged father can be used to find out paternity. IDENTIGENE can help identify what test will help give you the most conclusive results.
