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, and the father’s DNA is isolated.

This helps to achieve a more conclusive result. A sibling DNA test however, can still be performed without mom(s).

IF THE MOTHER(S) IS NOT AVAILABLE (FREE in standard tests), WE RECOMMED THE 46 MARKER TEST.

PaternityUSA.com represents the most trusted labs in the USA, and as such offers two of the best and most trusted DNA tests in the industry.

In general most labs like LabCorp®, Securigene®, Genetrace® (NOT A USA LAB!), Validity Genetics®, or Choice DNA® analyze 21-24 markers.

Our 24 marker sibling DNA test analyses 24 to 35 markers , and is the perfect option when the mom(s) is available for testing.

Our 46 marker sibling DNA test ALWAYS ANALYSES 46 MARKERS!  This is 90%+ more markers & is 1000 times more conclusive than the 21-24 marker DNA test, and is a great option when the mom(s) is not available to test.

In instances where the mom(s) is not available for testing, we recommend changing the test to our 46 marker product to ensure the most conclusive result. 

OUR 46 MARKER OPTION IS AN ACTUAL 46 MARKER DNA TEST AND NOT A FAKE MARKETING GIMMICK THAT PROMISES TESTING UP TO 46 MARKERS AS NEEDED OR IF APPLICABLE.

*** 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 you can trust.

Full Sibling: Siblings are known to have the same mother and want to test to see if they have the same father.

Half Sibling: Mother is known to be different, want to test and see if the father is shared.

Both: If you are unsure about the mother and/or father, like with adoptions cases, you can choose to have both the full and half sibling studies performed at the same time.

Cousins:  Sibling DNA testing DOES NOT WORK FOR POSSIBLE COUSINS!
