It’s generally recommended to add the mother to a sibling DNA test if possible.  Every person inherits half of their DNA from their mother and half from their father. When the mother is tested, her DNA is eliminated from the child. The remaining unmatched DNA is then known to be that of the biological father.  This would very precisely report if the DNA matched or was unmatched with the other possible brother’s or sister’s DNA.  However, the sibling DNA test can still be performed without the mother.


Our sibling DNA test can test up to 46 genetic markers.  The results produced, are the most trusted in the USA, and *** AS SEEN ON TV  *** shows such as Maury, Steve Wilco, Paternity Court. or national news stories, our lab is the go to lab for definitive answers.

Our premium sibling DNA tests analyze 24 markers which is 1000 times more powerful than the standard 16 marker test.  However we offer testing that is even more powerful than that.  In instances where the mom is not available for testing, if choose the option to test extra markers as needed, we can run additional markers (up to 46), where it is applicable. This is 90%+ more markers than the 24 marker DNA test offered by most competitors.
