What is the best ancestry and DNA testing service?

If your main goal is ancestry and finding relatives, my overall pick is AncestryDNA.

My ranking

1. Ancestry — Best overall for genealogy

• Generally the strongest choice for finding DNA relatives because of its very large customer database.
• Particularly good if you want to build a family tree and connect DNA matches to historical records.
• Best choice for “Who are my ancestors and who am I related to?”

2. 23andMe — Best for ancestry + health

• Strong ancestry reports, haplogroups, DNA relatives, and optional health-related reports.
• Its ancestry service includes DNA Relatives and ancestry reports.
• You can opt in or out of DNA Relatives and control several privacy settings.
• I'd choose it if you're interested in both genealogy and genetic health information.

3. MyHeritage — Best for international ancestry

• Particularly interesting if you have European, Jewish, or other ancestry outside the U.S.
• Its current ethnicity model covers 79 ethnicities, and its Genetic Groups provide more geographically specific information.
• It also accepts DNA uploads from other major testing services, which can expand your matching opportunities.

What I'd do

If you're only buying one test: get AncestryDNA.

If you're serious about genealogy, an even better strategy can be to test with AncestryDNA first and then upload your raw DNA data to compatible services such as MyHeritage. MyHeritage explicitly supports uploads from AncestryDNA, 23andMe and FamilyTreeDNA.

One important caveat: ethnicity percentages aren't literal facts. Different companies can give noticeably different percentages because they use different reference populations and statistical models. MyHeritage, for example, describes its ethnicity results as estimates rather than definitive classifications.

Bottom line:

• 🏆 Best overall: AncestryDNA
• 🧬 Best ancestry + health: 23andMe
• 🌍 Best for international ancestry: MyHeritage
• 🔎 Best approach for serious genealogy: test with AncestryDNA, then consider uploading the data elsewhere

If you tell me your ancestry background (e.g., African American, Irish, Italian, Jewish, Hispanic/Latino, Native American, mixed, etc.) and whether your priority is ethnicity, finding relatives, or building a family tree, I can tell you which test is likely to be best for your particular situation.

The "best" ancestry and DNA testing service depends entirely on what you want to get out of the test—whether that is building a family tree, finding living relatives, or discovering health predispositions.

The top services are broken down below by their primary strengths:

• AncestryDNA – Best Overall and Best for Genealogy
  • Why it’s great: It features the largest user database in the world (over 25 million people), giving you the highest probability of finding DNA matches and living relatives. It integrates seamlessly with Ancestry's massive historical records library and family tree-building tools.
  • Best for: Tracing your lineage, building family trees, and connecting with distant cousins.
• 23andMe – Best for Health Insights & Ethnicity Detail
  • Why it’s great: It is the gold standard for consumer genetic health reports, offering FDA-authorized insights on genetic health risks, carrier status for certain inherited conditions, and wellness/trait reports. Its ethnicity breakdown is also robust and user-friendly.
  • Best for: People who want a mix of interesting ancestry breakdowns and actionable health/wellness data.
• MyHeritage – Best Budget Option & Strong International/European Focus
  • Why it’s great: Frequently available at a lower price point than its competitors. It has a particularly strong database representation for European populations, making it a fantastic tool if your recent ancestors came from Europe, Scandinavia, or the Middle East.

Aside from standard autosomal testing, they offer specialized Y-DNA (paternal) and mtDNA (maternal) testing, allowing you to trace direct deep-ancestral lines across hundreds or thousands of years.
  • Pros: Deep lineage tracking, allows raw data uploads from other companies.
  • Cons: Smaller database for general casual relative matching.

If you'd like to narrow this down, tell me:

• Are you more interested in finding living relatives / building a family tree or health and wellness insights?
• Do you have a specific geographic region (e.g., UK, Europe, Scandinavia) you are trying to trace?

I can help you pick the ideal kit for your specific goals.

The best ancestry DNA testing service for most people is AncestryDNA. It has the strongest combination of a very large relative-matching database, genealogy tools, and integration with family trees.

The “best” choice depends on what you want to discover:

My recommendation for most beginners

1. Buy AncestryDNA first.
2. Build a family tree (even a simple one with parents, grandparents, and known locations).
3. Consider uploading your raw DNA data to other compatible services (where allowed) to expand your potential matches.

Things to know before testing

• Ethnicity estimates are educated estimates, not exact measurements; they can change as companies update their reference databases.
• DNA matches are usually the most valuable part for genealogy because they can connect you with living relatives and help confirm family lines.
• Privacy matters: read each company’s policies on data storage, research participation, sharing, and deletion before submitting DNA.

If you tell me your main goal—finding unknown relatives, tracing a specific country/ethnicity, building a family tree, adoption research, or health information—I can narrow it down further.

If your main goal is ancestry and finding relatives, my top choice is AncestryDNA.

My ranking

1. Ancestry — Best overall

• Largest DNA-matching database, which gives you the best odds of finding cousins and previously unknown relatives.
• Excellent family-tree and historical-record integration.
• Strong ethnicity estimates and geographic “communities/journeys.”
• Particularly good if you have U.S. ancestry.
• Current comparisons consistently put it at or near #1 for ancestry research.

2. MyHeritage — Best for international/European ancestry

• Particularly useful if your family has European roots.
• Strong international genealogy database.
• A nice advantage: you can upload DNA data from other testing companies, expanding your potential matches.

3. FamilyTreeDNA — Best for serious genealogy

• Especially good if you want to investigate a specific paternal or maternal line.
• Offers dedicated Y-DNA and mitochondrial-DNA testing, which the other major services don't offer in the same way.

4. 23andMe — Best if health information matters too

• Historically strong for ancestry, haplogroups and health/trait reports.
• However, its recent ownership/bankruptcy history makes me more cautious about recommending it specifically for someone whose primary goal is genealogy.

What I'd do

If you're taking your first DNA test: get AncestryDNA.

Then, if you're serious about genealogy, you can potentially download your raw DNA data and upload it to other compatible services to find additional matches. MyHeritage and FamilyTreeDNA are particularly useful for this strategy.

One important distinction: ethnicity percentages are interesting, but DNA matching is generally much more useful for actually building your family tree and identifying relatives.

If you tell me what you're trying to find—for example, “I want to know whether I'm Irish/Scottish,” “I'm trying to find my biological father,” “I want to trace my African ancestry,” or “I want the most accurate ethnicity breakdown”—I can tell you which test is best for that specific goal.

The "best" ancestry and DNA testing service depends entirely on what you want to get out of the test—whether that is building a family tree, finding living relatives, or uncovering health predispositions.

The top services stand out in specific categories:

1. Best Overall for Genealogy & Finding Relatives: AncestryDNA

• Why it’s the best: AncestryDNA boasts the largest consumer DNA database in the world (over 25 million people), giving you the highest likelihood of finding living DNA matches and close relatives. Its ThroughLines tool automatically maps out how you might be related to matches by connecting your DNA data with public family trees.
• Best for: Beginners, people focused on building a family tree, and anyone wanting the largest possible pool of relative matches.
• Downside: It doesn't include a chromosome browser for advanced genetic genealogy mapping.

2. Best for Health & Wellness Insights: 23andMe

• Why it’s the best: 23andMe is the gold standard if you want a mix of ethnicity estimates and FDA-authorized genetic health risk reports, carrier statuses, and wellness traits. It also provides basic relative matching and haplogroup tracking (maternal/paternal deep ancestry lineages).
• Best for: Those who prioritize medical predispositions, carrier screening, and physical traits alongside basic ancestry.
• Downside: It is weaker for traditional family tree building, as it doesn't support public family trees natively.

3. Best for International & European Research: MyHeritage DNA

• Why it’s the best: While MyHeritage has a smaller database than Ancestry, it has a heavily international user base, making it exceptional if your recent ancestors came from Europe or the UK. It also includes powerful advanced tools like a chromosome browser and AutoClusters.
• Best for: Users with European roots or those who want advanced genetic matching tools (and the option to upload raw DNA data from other platforms).

4. Best for Deep Ancestry & Lineage: FamilyTreeDNA (FTDNA)

• Why it’s the best: FTDNA is one of the oldest genetic genealogy companies. Uniquely, they offer specialized Y-DNA (paternal line) and mtDNA (maternal line) testing in addition to standard autosomal testing.
• Best for: Advanced genealogists trying to break through brick walls in deep paternal or maternal ancestral lines.

Pro-Tip for Serious Researchers

Many genealogy enthusiasts use a hybrid approach: they test first with AncestryDNA to tap into the largest database, and then download their raw DNA data file to upload it for free or cheap to platforms like MyHeritage, FamilyTreeDNA , or GEDmatch to cross-reference other databases without paying for a whole new test.

If you share what your primary goal is (e.g., finding a biological parent/relative, tracing deep ethnic heritage, or checking health risks), I can help you pick the exact service that fits your needs.

Best options

🥇 Why I'd choose AncestryDNA

ancestry.com has a major advantage: the combination of its DNA-relative database and enormous genealogy-record collection. Its current offering includes DNA matches, ancestral origins, and access to records covering thousands of places worldwide; some advanced features require a subscription.

That makes it particularly good if you want to answer questions like:

• Who are my biological relatives?
• Where did my grandparents/great-grandparents come from?
• Can I identify an unknown biological parent or grandparent?
• Can I build a documented family tree?
• Which branches of my family came from Europe, Africa, Latin America, etc.?

When I'd pick something else

23andMe is appealing if you primarily want a polished ancestry experience and detailed genetic reports. Its Ancestry service provides ancestry composition and DNA-relative matching, with the latter requiring you to opt in.

MyHeritage is especially worth considering if your family has substantial European or international roots. Its current system provides ethnicity estimates across 79 ethnicities and Genetic Groups covering 2,100+ geographic regions, and it can match DNA data uploaded from several other testing services.

One important caveat

Don't treat ethnicity percentages as exact facts. They're statistical estimates, and different companies can give you noticeably different percentages because they use different reference populations and algorithms. MyHeritage, for example, explicitly describes its ethnicity results as estimates.

Also, DNA privacy matters. Before testing, look at whether you can opt out of relative matching, delete your DNA data, and control sample storage. For example, Ancestry says DNA data is retained until you delete your results or account, while 23andMe allows you to opt out of DNA Relatives.

Bottom line: If you're buying just one test, I'd start with AncestryDNA. If you tell me your ancestry background (e.g., Irish, Italian, African American, Hispanic/Latino, Eastern European, mixed) and whether you're mainly interested in ethnicity, finding relatives, or building a family tree, I can tell you which test is likely to be best for your particular situation.

• 23andMe (Best for Ethnicity & Health Insights): Known for its user-friendly interface, 23andMe provides a great breakdown of your biogeographical ancestry alongside optional FDA-authorized health predisposition and carrier status reports. (Note: Feature availability and depth can vary based on current product offerings). [1]
• MyHeritage DNA (Best Budget & International Option): Frequently offering lower baseline kit pricing, MyHeritage has a strong international user base. It is a solid alternative to Ancestry if your family roots are outside the United States, and it includes robust family tree-building tools.
• Living DNA (Best for Detailed Regional Breakdown): If you want a more localized look at your ancestry—particularly down to specific sub-regions in the British Isles and Europe—Living DNA focuses heavily on fine-scale recent and deep ancestry mapping.

If you can tell me what your primary goal is—whether it's finding living family members, building a family tree , or exploring health traits —I can help you choose the exact service that fits your needs.

If your main goal is ancestry/genealogy rather than medical genetics, my overall pick is AncestryDNA.

My ranking

1. Ancestry — Best overall

• Best choice for finding relatives and building a family tree.
• Particularly strong because the DNA results integrate with Ancestry's enormous genealogy-record database—currently advertised as 70+ billion records.
• Excellent DNA-match tools and useful features for determining which side of your family a match comes from.
• My pick for most people.

2. MyHeritage — Best alternative / especially good for international ancestry

• Strong international user base, particularly useful if your ancestors came from Europe or other countries outside the U.S.
• Currently offers ethnicity estimates covering 79 ethnicities plus Genetic Groups spanning 2,100+ geographic regions.
• It can also match DNA uploaded from AncestryDNA, 23andMe and FamilyTreeDNA, although availability/features for uploaded data can differ.
• I'd seriously consider this if you have predominantly European ancestry.

3. 23andMe — Best for ancestry + genetic traits

• Particularly good for exploring ancestry composition, haplogroups and genetic relatives.
• Its ancestry service compares DNA against populations from 2,000+ locations and territories and includes maternal/paternal haplogroup information.
• Its DNA Relatives feature is optional, with privacy controls that let you opt out entirely.
• I'd choose it if you're more interested in genetics itself than traditional genealogy.

What I'd do

If you're willing to take only one test, I'd get AncestryDNA.

If you're serious about genealogy, there's an even better strategy: test with AncestryDNA first, then consider testing with MyHeritage as well. Different companies have different databases, so you can potentially discover relatives that don't appear in one company's results.

One important caveat: ethnicity percentages aren't literal measurements of your ancestry. They're statistical estimates, and neighboring populations can be difficult to distinguish. MyHeritage, for example, explicitly describes its ethnicity results as estimates and notes that genetically similar populations can produce ambiguous results.

If you tell me what you're trying to discover (e.g. African ancestry, European ancestry, Native American ancestry, unknown biological parent, finding relatives, building a family tree, or health risks), I can tell you which test I'd buy specifically for that purpose.
