What Is Raw DNA Data?
Raw DNA data is the digital file containing your unique genetic code, as determined by a consumer DNA test. It lists your personal genotype results—the specific sequence of A, T, C, and G DNA letters—across hundreds of thousands or even millions of points in your genome called SNPs (Single Nucleotide Polymorphisms). Each testing company records these results in a file, typically as plain text (.txt, .csv) and often provided in a compressed .zip format.
A snippet of a typical raw DNA data file looks something like this:
The file contains no interpretations about ancestry, health, or traits—just the raw "letters" your DNA test found. Those insights come from analyzing this data.
Why Download Your Raw DNA Data?
Most DNA testing companies show you only some reports or features by default. Downloading your raw DNA data gives you:
-
Access to More Tools and Reports Upload your file to external platforms (like GEDmatch, Promethease, GenePlaza, Impute.me, etc.) for more detailed reports on ancestry, traits, health risk, and wellness.
-
Results Comparison Different companies use different databases and algorithms. Upload your data elsewhere to compare ethnicity estimates, cousin matches, or health insights.
-
Specialized Analysis External tools can look for things your original test might not cover—such as rare traits, advanced genealogy, or polygenic (complex) health risks.
-
Data Backup Retain a copy of your raw data in case the company changes its policies, gets acquired, or discontinues your account.
-
Research Participation Some research or citizen science sites allow you to contribute your raw data to medical, genetic, or genealogical research projects.
-
Control and Privacy Having your own copy gives you fuller control over when/where to use or share your sensitive genetic information.
-
Use in Other Applications Advanced users may analyze their raw files in personal genomics, genealogy software, or bioinformatics tools.
Caution: Always protect your raw DNA data—it contains sensitive and personal information about you (and potentially your family).
