Merge Your DNA Files Into One Superkit

When the same SNP has different values in different files (which can happen due to genotyping errors or no-calls), our algorithm applies quality-based resolution. We prioritize calls with higher confidence and use consensus when possible. Most conflicts are rare (typically less than 1%) and have minimal impact on overall results.

The increase depends on which companies you're merging. For example, combining a 23andMe v5 file (~640,000 SNPs) with an AncestryDNA file (~700,000 SNPs) typically results in a Superkit with over 900,000 unique SNPs—roughly 30-50% more than either file alone. Adding a third file can push coverage even higher.

Superkits work great with GEDmatch (including Genesis), MyTrueAncestry, DNAGENICS, Promethease, Genvue, DNA.Land, and most third-party analysis tools that accept RAW DNA uploads. Note that some platforms like 23andMe, AncestryDNA, and MyHeritage only accept their own original test results and won't accept uploaded files.

Most Superkits are completed within 72 hours. The Starter Pack option includes priority processing for faster turnaround. You'll receive an email notification when your merged file is ready to download from your private account.
