Non-Legal Sibling DNA Test $125 | 34 Marker Test

THE ANSWER IS SIMPLE, Our labs perform 3 of 4 relational tests in the USA, and so sales volume allows us to deeply discount our pricing.  We do not however offer a cheap price on the back of a low quality DNA test, our mission is to provide ANSWERS YOU CAN TRUST AT PRICES YOU CAN AFFORD!

The fact is, our 46 marker sibling DNA tests analyze more markers than any other USA lab including LabCorp®.

Don’t just take our word for it, we have 100’s of real 5 Star Reviews from actual customers.

The only thing cheap about our sibling tests, is the price.

Our sibling DNA test results are ready in 2-3 days, but the overall time frame for you to get your results starts at the beginning with how/when your kit is sent to you. WE SHIP SAME DAY!! If you place your order before 12:00 PM (EST), your kit will ship same business day.

Relational DNA testing may not be as conclusive as a paternity test, but there are (2) factors that can dramatically help achieve a much more conclusive answer.   

It’s generally recommended to add the mother to a sibling DNA test if possible.  The mother can be added for FREE on our standard DNA tests.

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, WE  RECOMMEND THAT YOU CHOOSE THE 46 MARKER TESTING OPTION, BUT YOU CAN STILL CHOOSE THE 24-34 MARKER TEST WITHOUT THE MOM.

PaternityUSA.com  offers the best and most trusted relational DNA tests in the industry.

In general most labs only analyze test 20-22 markers.

Our standard sibling DNA test analyses 24-35 markers, and is the perfect option when the mom is available for testing. Mom can be added for FREE on our standard DNA tests.

Our 46 marker sibling DNA test ALWAYS ANALYSES 46 MARKERS!  That's more than twice as many markers & is 1000 times more conclusive than the 20-22 marker DNA test. 

Our premium 46 marker test is the best option when only the siblings are available to test.

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