Can I upload multiple files for the same person?

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:

1. Upload your first DNA file normally
2. Upload your second DNA file as a new sample
3. Repeat for any additional test files
4. 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
