AncestryDNA vs 23andMe: Which is Better?
Updated: Oct 2
If you are comparing AncestryDNA vs 23andMe, the better DNA test depends on what you want to learn.
Choose AncestryDNA if your main goals are finding DNA relatives, building a family tree, researching historical records, and exploring ethnicity estimates [R]. Choose 23andMe if you want ancestry results together with built-in health, carrier-status, wellness, and pharmacogenetic reports, depending on the service and country in which they are available [R].
Both companies also let eligible customers download raw DNA data. That file can be useful if you want to explore supported markers beyond the reports shown in the original account.

AncestryDNA vs 23andMe: The Main Difference
For ancestry combined with family-history research, AncestryDNA is the stronger choice.
Ancestry emphasizes a very large consumer DNA network and connects genetic matches with family trees and historical records [R]. That combination can be particularly useful when you want to:
identify biological relatives;
build or verify branches of a family tree;
investigate shared surnames and locations;
combine DNA evidence with genealogical records;
organize matches by parental side.
AncestryDNA’s ethnicity estimate—now commonly presented through its ancestral-origins features—is still an estimate. It compares sections of your DNA with reference groups and applies the company’s current statistical model. The percentages may change when reference panels and methods are updated, even though your DNA has not changed [R].
23andMe also provides detailed ancestry composition, genetic groups, relative matching, and haplogroup information. It may be more appealing if you are interested in broad genetic ancestry but do not need Ancestry’s deeper family-tree and historical-record workflow [R].
Neither service can guarantee that every ancestor, country, or community will be identified. Results depend on the reference populations, the DNA you inherited, the database, and how each company defines its regions.
Which Is Better for Finding Relatives and Building a Family Tree?
AncestryDNA has the clearer advantage for genealogy.
The number and usefulness of your matches depend on who else has tested and chosen to participate in matching. Ancestry’s large DNA database and integration with family trees can make it easier to turn a match into a genealogical lead. Its historical records can then help you investigate whether the proposed connection is supported by documentary evidence [R].
23andMe offers DNA Relatives and lets users explore predicted relationships and shared DNA. It can still identify important relatives, but it is not built around the same record-search and family-tree system.
If you are an adoptee, donor-conceived person, or someone looking for an unknown biological relative, the most useful database is ultimately the one containing that relative or a close family member. No comparison can predict that in advance. Testing with a second service may sometimes expand the matching pool, but it should be a deliberate decision rather than an assumption that one database will contain the person you seek.
Is 23andMe better for health reports?
For built-in consumer health reports, 23andMe is the stronger option [R].
Its qualifying services may provide reports across categories such as:
selected genetic health risks;
carrier status;
wellness;
traits;
pharmacogenetics.
The exact reports available depend on the product, membership, country, regulatory requirements, and the customer’s eligibility. Check the current report list for your location before purchasing. AncestryDNA’s current standard service focuses on ancestry, relatives, genealogy, and traits rather than built-in medical health reports. Ancestry previously offered AncestryHealth, but that service was discontinued in 2020 [R].
Do not use a direct-to-consumer result to diagnose a condition or independently start, stop, or change medication. Results with medical implications should be discussed with a qualified healthcare professional and confirmed when appropriate.
What About Traits and Wellness?
Both companies offer non-diagnostic trait information, but the presentation and available categories differ.
Ancestry’s traits products connect selected genetic markers with characteristics such as appearance, sensory responses, performance, and nutrition-related tendencies. Availability may depend on the kit or add-on purchased. 23andMe includes trait and wellness reports within qualifying service levels.
These reports can be interesting, but they should not be read as fixed predictions. Traits are often influenced by many variants as well as age, environment, behavior, and experience. Two people with the same reported genotype may not display the trait in the same way.
AncestryDNA vs 23andMe Accuracy: Which Is More Accurate?
There is no responsible single-word winner because accuracy can refer to several different things.
Genotype accuracy
Both companies analyze selected positions in DNA obtained from a saliva sample. A called genotype answers which DNA letters were detected at a tested marker. However, neither consumer genotyping file is a complete sequence of your genome, and different chip versions may test different sets of markers.
Ethnicity-estimate accuracy
An ethnicity estimate is a statistical interpretation, not a direct reading of a country from your DNA. AncestryDNA and 23andMe use different reference populations, region definitions, algorithms, and update schedules. The same person can therefore receive different percentages without either result necessarily being a laboratory error.
Broad regional signals may be more stable than small percentages assigned to closely related populations. Treat precise percentages as estimates that can evolve rather than permanent measurements of identity.
DNA-match accuracy
Close biological relationships supported by substantial shared DNA are generally more informative than distant predicted relationships. The usefulness of the result also depends on participation in the company’s matching database, family-tree information, and correct interpretation of how much DNA is shared.
Health-report accuracy
A tested variant can be identified correctly while the report still represents only one part of a person’s health picture. Different services may test different variants or use different evidence criteria. The FDA specifically warns that direct-to-consumer tests should not be the sole basis for medical decisions [R].
The practical answer is:
choose AncestryDNA for the stronger genealogy context;
choose 23andMe for a broader built-in health-report experience;
do not interpret either service as complete clinical genetic testing.
Can You Download and Use the Raw DNA Data Elsewhere?
Yes. Both AncestryDNA and 23andMe allow customers to request or download a copy of their raw DNA data through their account settings.
A raw DNA file usually lists:
a marker identifier, often an rsID;
the chromosome;
the genomic position;
the genotype recorded at that marker.
GenesUnveiled supports compatible raw DNA files from AncestryDNA, 23andMe, and other major providers. During normal analysis, you select the file on your device and the required genotypes are matched locally in your browser. GenesUnveiled does not receive or store the raw DNA file or per-variant results during this process. You can read more about how GenesUnveiled builds and reviews DNA reports.
Privacy and Control of Your Genetic Data
Privacy should be part of the decision before testing, not an afterthought.
AncestryDNA and 23andMe need to receive your saliva sample and genetic data to provide their services. Before purchasing, review the current terms for:
DNA-relative matching;
research participation;
sample storage;
data downloads;
account and result deletion;
data sharing and service providers;
what happens if ownership or corporate structure changes.
Ancestry provides controls for downloading DNA data, managing matching, deleting DNA results, and requesting destruction of a stored sample, subject to its current procedures and legal obligations [R].
23andMe provides controls for research participation and account deletion. It explains that some information may be retained where legally required and that information already used in completed or published research cannot necessarily be withdrawn from those results [R].
Which Test Costs Less?
There is no permanent price winner.
Both companies change promotions, bundles, memberships, and regional availability. The lowest advertised kit price may also exclude the feature you actually want.
Before checkout, compare:
the price of the required kit;
whether traits or health reports require a higher tier;
whether ongoing access requires a membership;
whether genealogy records require a separate Ancestry subscription;
shipping, taxes, and availability in your country;
which features remain available if you cancel a membership.
Buying the cheaper kit is not a saving if it does not provide the database, report category, or workflow you need.
Final Verdict: Is AncestryDNA or 23andMe Better?
Choose AncestryDNA if your priorities are:
finding relatives;
building a family tree;
connecting DNA matches with historical records;
exploring ancestry within a genealogy-focused platform.
Choose 23andMe if your priorities are:
ancestry plus built-in health-related reports;
carrier-status and wellness information;
pharmacogenetic reports offered within the service;
haplogroup and other genetics-focused ancestry features.
If you already have a file from either company, download and keep a secure copy before buying another test solely for additional interpretation. Your existing file may contain supported markers that can be explored through compatible raw DNA analysis tools.
Frequently Asked Questions
Is AncestryDNA or 23andMe better?
AncestryDNA is usually better for family trees, historical records, DNA matches, and genealogy. 23andMe is usually better if you want ancestry together with built-in health, carrier-status, wellness, and pharmacogenetic reports, where available.
Which is more accurate, AncestryDNA or 23andMe?
Neither is universally more accurate. Genotype calls, ethnicity estimates, relative matching, and health interpretations are different types of results. Each company uses its own tested markers, reference groups, algorithms, and databases, so the answer depends on what you are comparing.
Does AncestryDNA provide health reports?
The standard AncestryDNA service focuses on ancestry, relatives, genealogy, and traits. Ancestry’s former AncestryHealth service was discontinued in 2020 [R]. If built-in consumer health reports are a priority, 23andMe currently offers the broader option, depending on product and region.
Can I upload 23andMe raw data to AncestryDNA?
Do not assume that a 23andMe file can replace an AncestryDNA kit or reproduce the complete Ancestry origins-and-matching service. Ancestry’s public testing process is based on its registered saliva kit, although its current legal documents also refer broadly to uploaded DNA Data. Check the upload options actually offered in your account and region. In the other direction, an AncestryDNA file cannot replace a 23andMe saliva test. Either downloaded file may still work with compatible independent analysis tools.
Can I download raw DNA from both companies?
Yes. Both AncestryDNA and 23andMe provide procedures for downloading raw genotype data. Store the file securely because it contains sensitive genetic information.
Are 23andMe health results a diagnosis?
No. They cover selected variants and do not determine your complete risk of developing a condition. Do not use a consumer genetic result alone to diagnose a condition or change medication or treatment. Discuss medically important findings with a qualified healthcare professional.
