DNA Cousin Test

Private Knowledge DNA Cousin test from $150 and Legal DNA Cousin test from $255
The DNA cousin test is recommended for situations where the alleged father/parent is not available for testing. The DNA cousin test will provide the likelihood that individuals suspected to be cousins are indeed true biological cousins. This test is commonly ordered by grown individuals who suspect that their parents may be siblings and want to investigate the possibility.


Need a legal test? Legal testing starting at $230.


Important! Please note that the DNA cousin test is not as powerful as a DNA paternity test/parentage test and it is not as powerful as a DNA sibling test. If the alleged parent(s) in question is/are available for testing, we highly recommend the paternity test or maternity test over the DNA cousin test. If the parents of the alleged cousins are available to take the sibling test, the sibling test would be recommended over the cousin test since the sibling test (although not as powerful as a parentage test) is more powerful than a cousin test. The cousin test should only be considered if absolutely no other test type can be taken as it is the least powerful of all of the available kinship tests. While the DNA paternity and maternity tests will always provide absolutely conclusive results, the DNA cousin test will provide a likelihood that the individuals are cousins versus not related at all.
