Here at FamilyTreeDNA (FTDNA), 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.
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.

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