Upload Your 23andMe Raw Data for Real South Asian Ancestry (From $25)

If you tested with 23andMe or AncestryDNA from the US, UK, Canada, or Australia, you have probably hit the same wall every South Asian customer hits: your results collapse most of your heritage into a single grey blob labelled "Broadly South Asian." A genome that should distinguish a Punjabi Jat from a Tamil Brahmin from a Bengali Kayastha gets flattened into one undifferentiated region, because those companies were built around European and East Asian reference panels.

Here is the part most people miss: you do not need to spit into another tube to fix this. The raw data file you already paid for contains the same genetic information whether it is read by 23andMe's algorithm or Helixline's. You can simply download that file and upload it to Helixline, where it is re-analysed against thousands of curated South Asian reference samples. This guide walks through exactly how that works, what it costs internationally, and what you get back.

Why 23andMe and AncestryDNA say "Broadly South Asian"

Consumer DNA tests are only as good as the populations they compare you against. 23andMe and AncestryDNA hold enormous reference databases of European, African, and East Asian customers, but historically thin coverage of the Indian subcontinent and almost no caste- or region-level granularity. When their algorithm cannot confidently place your DNA into a narrow cluster, it falls back to the broadest label it can defend statistically: "Broadly South Asian," "Northern Indian & Pakistani," or similar.

That is not a limitation of your DNA. It is a limitation of their reference panel. The signal that separates a Saurashtra Gujarati from a Coastal Andhra Telugu is sitting right there in your file; it just has nothing meaningful to be compared against on a global platform.

What uploading to Helixline actually does

When you upload your raw data, Helixline runs it through a South-Asian-specialised pipeline with three stages:

1. Quality control & harmonisation. Your file (whether it came from a 23andMe v3, v4 or v5 chip, or from AncestryDNA, MyHeritage, FamilyTreeDNA, or LivingDNA) is cleaned, strand-aligned, and standardised so every provider's format maps onto the same coordinate system.
2. Imputation. Your chip read roughly 600,000–700,000 positions. Helixline statistically infers the millions of additional variants it did not read, using reference panels rich in South Asian genomes. This is the step that recovers the fine-grained ancestry signal. (We go deep on this in what DNA imputation is and why it matters.)
3. Ancestry prediction. Your imputed genome is compared against 2,500+ curated South Asian reference samples spanning 1,000+ sub-populations, plus ancient-DNA references (Indus Valley, Steppe pastoralist, and AASI). This yields state- and community-level breakdowns, ANI/ASI/AASI proportions, and Y-DNA / mtDNA haplogroups.

Step 1: Download your raw data

From 23andMe

Sign in at 23andme.com, go to your profile name → Settings → scroll to 23andMe Data → Download. Request the raw data file (not the report PDFs). You will receive a .zip or .txt file. With 23andMe winding down parts of its consumer business, downloading and safeguarding this file now is strongly recommended — see what to do as 23andMe shuts down.

From AncestryDNA

Sign in at ancestry.com → DNA → Settings → Download DNA Data. Confirm via the email link and download the .txt / .zip. Our dedicated walkthrough covers this in detail: downloading and uploading AncestryDNA raw data.

From MyHeritage, FamilyTreeDNA, or LivingDNA

Each provider exposes a "Download raw DNA data" option in account settings. Keep the file exactly as exported — do not open and re-save it in a spreadsheet, as that can corrupt the format.

Step 2: Upload and choose your report

Head to the Helixline upload page, choose your tier, and drag in your .txt or .zip. The transfer is encrypted, and you receive your results in your dashboard in about 7 days (24–48 hours for domestic Indian uploads).

How accurate is an uploaded result versus a fresh Helixline kit?

For ancestry, an imputed consumer-chip file gets you remarkably close to a native Helixline microarray. The reason is that ancestry is driven by hundreds of thousands of ancestry-informative markers spread across the genome, and imputation reconstructs the gaps with high confidence in well-studied populations. Where a fresh Helixline Decode or Infinite kit pulls ahead is in clinical-grade health and carrier-screening calls, which benefit from directly measured (rather than imputed) genotypes at specific medical loci.

In practice: if you mainly want ancestry, uploading is the smart, low-cost choice. If you want the deepest health, pharmacogenomics, and carrier-screening detail, the $50 upload covers most of it, and a fresh microarray kit is the gold standard.

Your data stays in India and stays yours

Uploaded files are encrypted in transit and stored on infrastructure located in India, under the Digital Personal Data Protection (DPDP) Act 2023. You can export or permanently delete your data at any time, and Helixline does not sell genetic data to third parties. For diaspora customers who watched 23andMe's database become an asset in bankruptcy proceedings, that ownership model matters — more on that in the best 23andMe replacement for South Asians.

Frequently Asked Questions

Can I upload my 23andMe raw data for South Asian ancestry analysis?

Yes. If you have already tested with 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA or LivingDNA, you can download your raw data file and upload it to Helixline instead of buying a new kit. Helixline re-analyses the same file against 2,500+ curated South Asian reference samples and returns state-level and community-level ancestry that the original test could not provide. Upload-only ancestry analysis starts at $25, with results in about 7 days.

How much does it cost to upload my DNA to Helixline?

There are two upload tiers. Ancestry-only is $25 (approximately £20, $34 CAD, $38 AUD) and includes state- and community-level ancestry, Y-DNA and mtDNA haplogroups, ANI/ASI/AASI ratios and ancient-DNA similarity. The full report is $50 (approximately £40, $68 CAD, $76 AUD) and adds 30+ health and wellness traits, carrier screening for South-Asian-relevant conditions, pharmacogenomics, and downloadable PDF reports. Both are one-time payments with no subscription.

What is genotype imputation and why does it matter?

Consumer chips from 23andMe and AncestryDNA only read about 600,000 to 700,000 positions in your genome. Imputation is a statistical method that uses reference panels of fully sequenced genomes to accurately infer the millions of variants the chip did not directly measure. For South Asian ancestry this is important because many of the markers that distinguish a Punjabi profile from a Tamil profile sit at positions your original chip never tested. Imputing against South-Asian-rich panels recovers that resolution from the file you already have.

Which raw data files does Helixline accept?

Helixline accepts unmodified raw data files (.txt or .zip) downloaded directly from 23andMe (v3, v4 and v5 chips), AncestryDNA, MyHeritage, FamilyTreeDNA and LivingDNA. The file must be the original export from the provider, not a screenshot or an edited spreadsheet. You download it from your provider's account settings and upload it during checkout on the Helixline upload page.

Is my DNA data safe and where is it stored?

Your uploaded file is transferred over an encrypted connection and stored on infrastructure located in India. Helixline operates under India's Digital Personal Data Protection (DPDP) Act 2023: you can request export or permanent deletion of your data at any time, and genetic data is never sold to third parties. This is a key difference from some global services where ownership of databases has changed hands during bankruptcies and acquisitions.
