What to do with your raw DNA data in 2026
If you took a consumer DNA test, you own a file. Most people never download it, and of those who do, most look at it once, notice it is several hundred thousand rows of letters, and put it away again.
The file is worth more than that. It is a fixed record of your genotype that any number of tools can read, and it does not expire.
What can I actually do with my raw DNA data?
Four things, broadly: find genetic relatives by uploading to genealogy databases, run it through interpretation services that read published research against your markers, re-run your ancestry against a different reference panel, and simply archive it. The first three are what the upload services exist for; the fourth costs nothing and keeps improving in value.
That last point deserves more attention than it gets. Your genotype does not change. What changes is the published literature about the positions in your file — which grows every year. A file downloaded in 2019 supports a better interpretation today than it did then, without you doing anything.
Are raw DNA data analysis services free?
Some are, some are not. In a survey of thirty services in August 2026, prices ran from free tools with limited scope, through one-off raw-upload reports at roughly $25–95, to subscription platforms at $199 a year and above. Promotions, VAT and region all move the number at checkout.
The pattern behind those prices is worth knowing. The underlying evidence — ClinVar, the GWAS Catalog, the PGS Catalog, CPIC, PharmGKB, gnomAD — is public and free. What is being charged for is the work on top: quality control on your file, choice and calibration of models, scientific curation, the report itself, and the security around your data.
Which means a paid service is not automatically reading better sources than a free one. It may simply be doing more with the same sources — or it may not.
Which file formats do upload services accept?
Nearly all of them take the standard consumer array exports: 23andMe and AncestryDNA .txt, MyHeritage and FamilyTreeDNA .csv, LivingDNA and tellmeGen .txt, usually inside the .zip you were emailed. Some also accept VCF from whole-genome sequencing. You rarely need to unzip anything first.
If a service asks you to convert, reformat or manually edit your file before uploading, that is a small warning sign. The formats have been stable for years and reading all of them is not difficult.
What can raw DNA data analysis not do?
It cannot see anything the chip did not read. A consumer array covers roughly 600,000–700,000 pre-selected positions out of 3.2 billion base pairs, so most rare variants are simply absent from the file. No service, however expensive, can report on a marker that is not there.
This matters most for the genes people care about most. BRCA1 and BRCA2 are the standing example: consumer chips typically carry a few founder variants out of thousands known, so a file showing nothing there has ruled out very little — the reason carrier results need reading carefully.
The honest way to handle that gap is to report a missing marker as not covered, not as normal. It is also the fastest way to judge a service — look at whether it distinguishes the two at all.
How do I choose where to upload my DNA file?
Ask three questions, and get the answers from the privacy policy rather than the marketing page: is my data sold or shared, is it used for research or added to a database, and can I actually delete it. Then check whether the service says what it cannot see.
Those questions separate services more sharply than any feature comparison, because the answers are hard to fudge and easy to check. A deletion promise that only removes your account, while the file stays in a backup, is a different product from one where deletion destroys the key the file was encrypted with.
For what it is worth, that is the standard we hold ourselves to: your file is encrypted with a key belonging to that file alone, nothing is sold or shared, and the deletion link in your email destroys the key permanently. Hold every other service to the same test, including the free ones.
