Private raw DNA upload
Upload raw DNA data for a free health preview
Direct answer: Yes—you can upload a supported raw DNA export from 23andMe, AncestryDNA, or MyHeritage, or a whole-genome sequencing file in VCF format, and see a free personalised preview before paying. DNA Layer reads the original file locally and does not retain it. Coverage depends on the markers present; PDF reports are unsupported, and results are not diagnostic.
TellMeGen raw exports can also be tried, but support is newer and less thoroughly tested. No new DNA test is required if you already have a supported export.

- TellMeGen health analysis: Use the raw data export; support is newer and less tested.
Not sure what you have?
A raw DNA export is usually a ZIP or text file containing rows of marker data. It is not a PDF report, screenshot, or family tree. Use the free local file checker to inspect its structure without uploading it, or read the supported-provider comparison or the guide for older DNA test results.
Know the limits before you begin
DNA Layer is informational and educational. Consumer DNA files do not cover every possible variant, and findings are not diagnoses. Important results may require confirmation in a clinical laboratory and review by a qualified professional. Read how findings are matched and checked.
What happens when you continue
The email step takes you to DNA Layer’s Vault. There, the original raw file is parsed in your browser and filtered to the supported markers used for analysis. DNA Layer does not retain the original file. Derived genetic findings are still sensitive, so they remain private to your account until you delete them.
Read the complete data-flow explanation, inspect a representative report, or review the evidence and safety methodology before uploading.
Raw DNA upload questions
Which raw DNA files can I upload?
DNA Layer accepts the original raw-data ZIP or text export from 23andMe, AncestryDNA, and MyHeritage, and whole-genome or whole-exome sequencing files in VCF format (.vcf or .vcf.gz). TellMeGen support is newer and less tested. Do not upload a PDF report, screenshot, family-tree GEDCOM, or ancestry-coordinate file.
Does DNA Layer store the raw DNA file I upload?
No. DNA Layer reads the original file locally in your browser and does not retain it. Only supported marker derivatives and technical metadata needed for analysis are sent. The resulting derived findings remain private in your account so you can return to the layer, and you can delete them.
Is the DNA upload and preview free?
Yes. DNA Layer checks the supported markers in your file and generates a free personalised preview before you decide whether to purchase the full health layer. The full layer adds the complete findings, evidence context, action plan, and agentic report export.
Do I need a new DNA test before uploading?
No, if you already have a valid export from a supported provider. Coverage depends on the exact markers in that file. An older array can still be useful, but it cannot answer questions about positions it never tested; consequential findings may require an appropriate clinical test.
