SNP Assurance Program (Backbone SNP Test)

Here at FamilyTreeDNA, we want to provide our customers with the highest level of Y-DNA haplogroup confidence, so we created our SNP Assurance Program (which began with test batch 173). With the SNP Assurance Program, if we cannot predict your Y-DNA haplogroup with 100% confidence, we will test your sample for FREE with our Backbone SNP test in order to identify your haplogroup assignment.

What is the Backbone SNP test?

With our Backbone SNP test, we analyze a panel of SNPs to determine your placement on the haplogroup tree. The positive value for the SNP that determines your haplogroup assignment is reported on your Y-DNA - Haplotree & SNPs page. The following depth of haplogroup prediction or confirmation is guaranteed for all Y-DNA tests.

I tested before you implemented the SNP Assurance Program. My haplogroup is not predicted. Will you confirm my haplogroup? 

If you tested before we implemented the SNP Assurance Program and your Y-DNA - Haplotree & SNPs page shows your haplogroup as unpredicted, then we will run the Backbone SNP test for you.   Please use our contact form to submit a request for customer service.

How long does the Backbone SNP test take?

The Backbone SNP test takes 6–8 weeks from the time it is ordered.
