DNA Test Comparisons: Head-to-Head Across Every Major Brand

The honest comparison between two DNA tests rarely fits on a feature matrix. The Help Center pages list a lot of capabilities; what they tend to bury is which capability actually matters for your situation. A larger database means more matches, but does not help if your relatives all tested with the other company. A lower sticker price means little if the test you really want requires a $199 subscription to read.

This pillar gathers our head-to-head comparison articles. Each one looks at two or three tests against the criteria we think buyers actually weigh: matching database size and growth, raw-data download and free-upload policy, region availability, turnaround time after the lab receives the sample, the realistic discounted price, and the corporate situation behind the brand.

A few patterns are worth flagging before you read the deeper comparisons.

AncestryDNA wins on database size for matching purposes. Roughly 25 to 30 million tested users, against about 14 million at 23andMe and 5 to 8 million at MyHeritage. If finding distant relatives is your primary goal, this matters more than any other single spec.

MyHeritage and FamilyTreeDNA accept free uploads of raw data exported from AncestryDNA and 23andMe. That means a single $99 kit can yield matches in three databases at no extra cost, which changes the calculation for a budget-conscious buyer. Ancestry does not accept uploads.

23andMe is the only mainstream consumer test bundling FDA-authorized carrier and predisposition reports. The clinical scope of those reports is narrower than the marketing suggests, and the 2025 Chapter 11 filing has introduced real uncertainty about the company that holds the data. See the Privacy pillar before you decide whether the ancestry-plus-health bundle is worth the trade-off.

For region-specific buyers, Living DNA does a notably detailed British and Irish ancestry breakdown but has a small matching database. tellmeGen has strong European availability but a much smaller user base than the Big Three.

Whole-genome sequencing is now its own category. The consumer SNP tests above type about 700,000 positions in your genome; Sequencing.com, the active whole-genome service after Nebula Genomics shut down in February 2025, reads the entire genome. Worth knowing about, but rarely the right starting point for a first-time buyer.
