Supported DNA data

Raw DNA data interpretation with AI

Kantesti reads the raw data files of the major consumer DNA services and VCF files directly, and genetic reports from any laboratory as PDF or photos. Here is what is supported and how to get the file.

From DNA test kit to genetic report

DNA test kit and saliva tube beside TXT, CSV, VCF and ZIP raw DNA data files being uploaded to a secure server — **Raw DNA data files from consumer DNA tests**Raw files from 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA and LivingDNA are supported, as well as VCF, including files packed as .zip or .gz.

Genotyping microarray chip with coloured spots and a magnifying glass showing the genotype pairs AG, CT, GG and AT — **A genotyping array reads DNA as pairs of letters**Genotyping arrays report each marker as a letter pair such as AG or CT, and these pairs make up the raw DNA data file. Kantesti compares that file with 334 curated markers.

Rows of genotype pairs flowing through a filter funnel into a DNA helix with a 334 badge for the curated marker panel — **The raw genotype file, parsed down to 334 curated markers**The raw DNA file is parsed on the server and matched against 334 curated markers in 20 health areas. Every AI finding is then checked against the file.

DNA file card with three check marks, a gauge in the green zone and a shield, showing a raw DNA data quality check — **Quality check of the uploaded raw DNA file**The uploaded raw DNA file is read on the server, whether it comes from a consumer DNA test or a VCF. Every AI finding in the report is checked against that file.

How to download raw DNA data

Every service offers a raw data download in the account settings. Menu names change from time to time; the steps below describe the usual path.

23andMe

Sign in and open Settings.
Find the 23andMe Data section and request the raw data download.
Download the .zip file when the email arrives. Upload it as it is.

AncestryDNA

Sign in and open the DNA settings of the test.
Choose Download DNA data and confirm through the email you receive.
Upload the downloaded .zip file.

MyHeritage

Open the DNA menu and go to Manage DNA kits.
Choose Download for the kit and confirm by email.
Upload the .zip or .csv file.

FamilyTreeDNA

Open myDNA and the autosomal results.
Choose Download Raw Data and pick the build 37 file.
Upload the .csv.gz file.

LivingDNA

Open your results and the download section.
Download the raw data file.
Upload the .txt, .csv or .zip file.

VCF

Ask the laboratory or sequencing service for the VCF file.
Make sure the ID column carries rsIDs.
Upload the .vcf or .vcf.gz file.

What happens when you upload

The file is read on the server in a single streaming pass, so even an 80 MB export takes seconds. Only the 334 panel markers are kept; the rest of the genome is not stored.

The format and genome build are detected automatically.
The call rate and the number of panel markers found are shown in the report.
An unreadable or unsupported file is rejected at once, before any AI work.
A PDF or photo report is read by the AI directly, page by page.

Arrays, reports and sequencing

Consumer DNA tests are genotyping arrays: they read selected markers, not the whole genome, and they miss rare variants. A report is only as complete as the file behind it, and actionable findings should be confirmed with clinical genetic testing.
