What 23andMe does and what you get back

23andMe is a direct-to-consumer genetic testing company that analyzes your DNA from a saliva sample you mail in. You order a kit online, spit into a tube at home, mail it to their lab, and receive results through their website showing ancestry information and reports about genetic traits and health predispositions. The company does not diagnose diseases — it shows whether you carry certain genetic variants that research has linked to conditions, traits, or ancestry patterns.

When you order, you pay a flat fee upfront (the price varies by which reports you choose). You receive an set up code with your kit, register online, provide a saliva sample, and mail the kit back in a prepaid envelope. Results typically arrive within 4 to 8 weeks. You can then view your ancestry breakdown, see genetic matches to other 23andMe users, and read health reports if you purchased that tier.

The company stores your DNA data in their database unless you request deletion. They use this data for research and may share anonymized genetic information with pharmaceutical companies and researchers. You control these settings in your account and can change them at any time.

Key Takeaways

  • 23andMe sends you a kit to collect saliva at home, you mail it back, and receive ancestry and trait reports within weeks through a find online account.
  • The service offers different tiers: ancestry-only costs less, while health reports cost more and show genetic predispositions to certain conditions.
  • Results are not medical diagnoses — they show whether you carry genetic variants linked to traits or conditions, not whether you will develop them.
  • Your DNA data is stored by 23andMe and may be used for research unless you opt out in your account settings.
  • You should discuss any health-related findings with your doctor, because genetic risk does not mean you will get a condition.

Ancestry reports and DNA matching

23andMe breaks down your ancestry by region and percentage. The report shows what fraction of your DNA comes from different populations — for example, 45% European, 30% West African, 25% East Asian. These percentages are estimates based on comparing your DNA to reference populations, so they can shift slightly if 23andMe updates their database.

The service also connects you to genetic relatives who have also tested with 23andMe and chosen to share their results. You can see how closely related someone is (parent, sibling, cousin, distant relative) based on how much DNA you share. Many people use this feature to find unknown relatives or confirm family connections. You control whether your profile is visible to matches and can message other users through the platform.

Ancestry results do not change over time, but the company occasionally updates their regional breakdowns as they refine their reference data. If you want to read your raw DNA data, 23andMe lets you export it and upload it to other genealogy websites like Ancestry.com or MyHeritage.

Health reports and what they mean

If you purchase the health tier, 23andMe provides reports on genetic predispositions to conditions like heart disease, type 2 diabetes, Parkinson's disease, and certain cancers. The reports also cover carrier status — whether you carry a recessive gene for conditions like cystic fibrosis or sickle cell disease. Carrier status means you have one copy of a gene variant; you will not develop the condition yourself, but you could pass it to a child if your partner also carries it.

Each health report includes the strength of the genetic association, what the research says, and what lifestyle factors may influence your risk. For example, a report might say you have a 1.5x increased genetic risk for type 2 diabetes, then explain that diet and exercise still play a major role. The reports are not diagnoses and do not tell you whether you will develop a condition — only whether your genetic makeup puts you at higher or lower risk than average.

23andMe also reports on traits like caffeine metabolism, muscle composition, and whether you are likely to be a morning person. These are based on genetic variants but are influenced heavily by environment and behavior, so the predictions are less reliable than health risk reports.

How to order and what the process costs

You order directly from 23andMe's website. The ancestry-only kit is the least expensive option. The health plus ancestry kit costs more and includes reports on genetic predispositions and carrier status. Prices change periodically and the company runs sales, so check their site for current pricing.

Once you order, the kit arrives within a few days. Inside you will find a saliva collection tube, instructions, a prepaid return envelope, and an set up code. You follow the instructions to fill the tube to the line marked, seal it, and mail it back. The company provides tracking so you can see when it arrives at their lab.

Processing takes 4 to 8 weeks from the time the lab receives your sample. You receive an email when results are ready. You then log into your 23andMe account to view them. The results stay in your account indefinitely unless you request deletion.

Privacy, data storage, and what 23andMe does with your DNA

23andMe stores your DNA data and genetic information on their servers. By default, your profile is private and your data is not shared with third parties without your permission. However, the company does use aggregated and anonymized genetic data for research and has partnerships with pharmaceutical companies and research institutions.

You can control your privacy settings in your account. You can opt out of research participation, choose whether your profile is visible to genetic matches, and request that 23andMe delete your DNA sample and data. If you request deletion, the company destroys your sample and removes your genetic information from their database, though they may retain some anonymized data for research purposes.

Law enforcement can obtain your genetic data with a court order or warrant. 23andMe has received requests from police investigating crimes and has complied when presented with legal documents. If privacy is a major concern, review 23andMe's privacy policy and data request transparency reports before ordering.

When to talk to a doctor about your results

If your results show you are a carrier for a genetic condition, or if you have a family history of the condition mentioned in your health reports, discuss the findings with your doctor. Your doctor can order confirmatory testing, explain what the results mean for your health, and recommend screening or preventive steps if appropriate.

Genetic predisposition reports are not medical information. A higher genetic risk for heart disease does not mean you will have a heart attack — it means you may benefit from lifestyle changes, more frequent screening, or medication depending on your overall health picture. Your doctor can help you interpret the results in the context of your age, family history, and current health.

If you are pregnant or planning to become pregnant and your results show you are a carrier for a genetic condition, genetic counseling can help you understand the implications. Many insurance plans cover genetic counseling if your doctor refers you.

How 23andMe compares to other genetic testing services

Other direct-to-consumer DNA testing companies include Ancestry.com, MyHeritage, and FamilyTreeDNA. Ancestry.com focuses primarily on genealogy and has the largest database of genetic matches. MyHeritage offers ancestry and health reports at different price points. FamilyTreeDNA specializes in deep ancestry and haplogroup assignment for people interested in ancient migration patterns.

23andMe's main advantage is the size of its genetic match database — more users means more potential relatives to find. Its health reports are also well-regarded, though they are not a substitute for medical testing ordered by a doctor. The trade-off is that 23andMe's privacy policies and data-sharing practices are more permissive than some competitors, so if privacy is your priority, compare their policies to others before ordering.

If you are primarily interested in genealogy, Ancestry.com may be a better fit. If you want only health information, clinical genetic testing ordered through your doctor may be more appropriate, because it includes genetic counseling and is covered by insurance in many cases.

Frequently Asked Questions

How accurate are 23andMe ancestry results?

Ancestry estimates are typically accurate within a few percentage points, but they are not exact. 23andMe compares your DNA to reference populations, and the breakdown depends on which populations are in their database. The company updates these estimates periodically as they add more data, so your results may shift slightly over time. Ancestry results are most reliable for broad regions and less precise for specific countries or subregions.

Can 23andMe results be used to diagnose a disease?

No. 23andMe health reports show genetic predispositions and carrier status, not diagnoses. A report saying you have increased genetic risk for a condition does not mean you have it or will develop it. If you are concerned about a health condition, see your doctor for medical testing and evaluation.

What happens if I want to delete my DNA data?

You can request deletion through your account settings. 23andMe will destroy your DNA sample and remove your genetic profile from their database. Some anonymized data used for research may be retained, but your personal information and identifiable genetic data will be deleted. The deletion process takes a few weeks to complete.

Can I read my raw DNA data and use it elsewhere?

Yes. 23andMe lets you read your raw genetic data in a standard format. You can then upload this file to other genealogy websites like Ancestry.com or MyHeritage to find additional matches or get different ancestry breakdowns. This is useful if you want to explore your results on multiple platforms.

Will my health insurance cover 23andMe testing?

Direct-to-consumer 23andMe testing is not covered by insurance because you order it yourself without a doctor's order. If your doctor orders clinical genetic testing through a lab, that may be covered depending on your plan and the reason for testing. Check with your insurance company about coverage for medical genetic testing.
