Yes! You can and should upload multiple test files for the same person to maximize your genetic data coverage:
Benefits of Multiple Files:
- Increased SNP Coverage: Each company tests different markers
- Better Analysis: More data points = more accurate results
- Comprehensive Reports: Access to more detailed predictions
- Comparison: See how different tests complement each other
How to Upload Multiple Files:
- Upload your first DNA file normally
- Upload your second DNA file as a new sample
- Repeat for any additional test files
- Optionally, use our Merge Service to combine them into one super-file
Merging Service:
For the best experience with multiple files:
- Purchase our "Merge RAW Files" service
- Combine 2+ files from the same person
- Get a single merged file with maximum SNP coverage
- Use the merged file for all future analysis
- Benefits: 1-2 million+ SNPs instead of 600K-700K
Organizing Multiple Files:
- Label each sample clearly (e.g., "23andMe Test", "Ancestry Test")
- Keep track of which companies provided which files
- Note: Each file counts as a separate sample in your account
Recommended Combinations:
- 23andMe + AncestryDNA (excellent for haplogroups + coverage)
- MyHeritage + FTDNA (good coverage combination)
- Any combination maximizes your genetic insights
