The real reason most people spit in a tube isn’t a pie chart of regions—it’s a name. It’s a parent, a grandparent, or a cousin you never knew existed. The single most important feature in a relative-finding DNA test is the size of the database it checks against; a bigger database means more chances a close match has also tested. This guide cuts through the marketing to rank the kits that actually connect you to living family members, not just ancient origins.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
We’ve weighed database reach, matching tools, and turnaround times to find the best DNA test for finding relatives that delivers real family connections.
Our Picks at a Glance
How To Choose The Best DNA Test for Finding Relatives
Finding a relative is a numbers game. If the person you’re looking for hasn’t tested with the same company, you simply won’t match. The biggest databases give you the best odds, but they also come with choices about subscriptions and tools you need to understand.
The Database is Everything
Your DNA is only as useful as the pool it’s compared against. A test with a small database might give you a handful of distant matches, while a massive one can surface second cousins you never knew existed. When the goal is finding relatives, prioritize the company with the most users and the most active family trees.
Relative Matching vs. Ethnicity Estimate
An ethnicity estimate tells you what regions your ancestors came from thousands of years ago. Relative matching, often called a DNA Relatives list or Family Finder, shows you living people who share DNA with you. The latter is what actually puts you in touch with family members. Check that the kit includes a matching tool you can use without a paid subscription.
The Subscription Reality
Many services give you the raw DNA match list for free, but charge a monthly fee to see shared family trees, historical records, and messaging tools. Some kits bundle a few months of access into the price. Understand what’s included and what lapses after the trial ends before you commit your saliva.

In‑Depth Reviews
1. AncestryDNA Personalized Genetic Test
Our pick — over 4.5★ from 91,000+ verified ratings; the strongest balance of quality and price.
The giant database that turns a spit sample into a pile of cousin connections.
The single biggest reason to choose Ancestry is the size of its matching pool. For finding living relatives, that’s the whole game, and this kit sits on top of the largest consumer database in the category. Owners describe the experience as an eye-opening look at their heritage, with one summing it up as a great starter kit that needs just a simple saliva sample, prepaid postage, and delivers results in about five weeks.
The ethnicity report spans over 3,600 regions around the world, giving you a detailed breakdown of where your ancestors lived. Its SideView technology takes this further by showing you which of your origins and matches came from each parental side, without needing a parent to test. That feature can be a huge shortcut when you’re trying to figure out whether a match belongs to your mom’s or dad’s family.
You get full control over your genetic data and decide what to share. The catch is that some of the best tools, like building a full family tree and accessing the record collections, require an Ancestry subscription. Buyers report the results are highly detailed and fast, but the raw DNA breakdown only takes you so far before the paywall appears.
What wins people over
- Simply activate, spit, and mail back the prepaid package
- Results land online in roughly six weeks
- SideView technology separates matches by parent
The trade-offs to know
- Deep family tree features sit behind a subscription
- Ethnicity descriptions can feel inaccurate for some
Reach for this if: you want the best statistical chance of matching a close relative because the database is the largest.
Look elsewhere if: you refuse to pay a subscription to open up the tree and record tools you’ll want after the results land.
2. AncestryDNA + 3-Month World Explorer
The same huge database as the top pick, with the family records access thrown in.
This is the AncestryDNA kit bundled with a 3-month World Explorer membership, which open up billions of family history records during that window. Owners mention the included membership is worth it, especially if you plan to do a deep dive right after your results arrive. It makes the most of that initial wave of curiosity before the subscription lapses.
It gives you the same top-selling DNA test with access to over 3,600 regions, plus the ability to see your origins and DNA matches separated by which side of the family they came from. The 3-month membership is redeemable only during the activation process by the person activating the kit, so you can’t pass it along to a relative later.
The kit is compact—unlike the 9.5 x 5.5 x 1.7-inch original, this one measures in at just 6.37 x 4.37 x 0.93 inches—so it slips into a drawer easily. Some owners have joked that it’s a small kit for the cost, but the included access to millions of family trees and the world’s largest collection of online records makes the package worth it if you know you’ll use the trial.
Why it earns its spot
- Bundles a 3-month World Explorer membership
- Compact package that stores easily
- Access to billions of family history records
Before you buy
- Membership must be redeemed by the person activating the kit
- It may auto-renew if you submit billing information
Pick this if: you know you’ll want to dive into family records immediately and want the trial built into the price.
Think twice if: you’ll only look at your results once and don’t need the extra months of record access.
3. 23andMe Ancestry Service
The most detailed geographic breakdown on the market, sometimes down to a specific valley or village.
While Ancestry wins on database size for relative matching, 23andMe wins on the depth of its ancestry composition. It estimates your origins across 4,500+ geographic regions and can sometimes trace your ancestors to a specific valley or village they hailed from. Buyers who have tested with both often say the ethnicity estimates here feel more precise and detailed than what Ancestry provides.
The DNA Relative Finder opt-in connects you with people who share your DNA, and the Automatic Family Tree builds your tree from those genetic relationships. The kit also includes over 30 personal trait reports—covering things like cilantro aversion, perfect pitch, and mosquito bite risk—which makes it a more entertaining gift. It’s listed in TIME’s Best Inventions Hall of Fame 2025.
Collection is a simple saliva sample with no blood and no needles. You register online, spit in the tube, and mail it back in the prepaid box, with reports arriving in 4–5 weeks. The honest trade-off is that the relative matching database is smaller than Ancestry’s, so you may find fewer close matches if your family hasn’t tested with 23andMe.
What makes it stand out
- Access to over 4,500 geographic regions
- Includes 30+ personal trait reports
- Automatic Family Tree from DNA matches
What to weigh
- Smaller match pool than Ancestry for finding relatives
- Advanced ancestry upgrades cost extra
Go for this if: you care more about pinpointing your geographic origins than maximizing the number of cousin matches.
Consider the alternative if: finding every possible living relative is your primary goal and you want the biggest database.
4. FamilyTreeDNA Family Finder
The genealogist’s tool for comparing exact DNA segments, not just lists of names.
FamilyTreeDNA takes a different approach than the big two. Instead of just handing you a list of matches, it gives you a Chromosome Browser so you can compare the specific DNA segments you share with each relative. Buyers who take genealogy seriously say this is the tool they use to figure out how exactly they’re connected to a match.
Collection is a simple cheek swab—an option that some customers note is ideal for elderly relatives who might struggle with spitting into a tube. Results for ethnicity typically arrive in about two weeks, with Y-DNA results taking a few weeks more. The myOrigins Chromosome Painter colors in your genome to show where each DNA segment came from.
The clear trade-off is the smaller match pool. The database is growing, but it’s nowhere near Ancestry’s size, so you’ll likely get fewer close matches. There’s no subscription fee, which is a big plus for budget-minded genealogists, and the same sample can be upgraded for Y-DNA or mitochondrial DNA testing later without collecting a new one. Know that there’s no mobile app—the whole experience is web-based.
What serious users love
- Chromosome Browser for comparing shared DNA segments
- Cheek swab sample, ideal for elderly users
- No subscription fees to access your matches
The honest limits
- Smaller database means fewer close matches
- Web-only experience with no dedicated app
Choose this if: you’re a genealogy hobbyist who wants to analyze the actual DNA segments you share.
skip it if: you just want the highest chance of a quick close match and prefer the massive Ancestry database.
5. 23andMe Health + Ancestry Service
The kit that answers the family question and the health question from one saliva sample.
If you want to find relatives but also want to know about your genetic health risks, this is the all-in-one answer. It bundles the full Ancestry Service—including DNA Relative Finder—with 100+ personalized genetic insights, covering health predispositions, carrier status, and wellness. Buyers describe the results as deeply informative, with one noting the experience was a great investment that relieved anxiety by showing they lacked variants for family diseases.
The health reports are FDA-authorized, meaning the results have been reviewed for clinical validity. It goes beyond simple ancestry to report on things like lactose intolerance and celiac risk. A portion of your purchase may be eligible for FSA/HSA reimbursement, which is worth checking if you pay for healthcare with one of those accounts.
Like the standard kit, it’s a simple saliva collection with results in 4–5 weeks. The relative matching is the same as the regular Ancestry service, so you won’t get more matches here—you’re paying for the health data on top. Some owners note that trait predictions aren’t always spot on, so treat those as entertainment rather than gospel.
The all-in-one appeal
- 100+ reports covering health and ancestry
- FDA-authorized health predisposition reports
- Includes carrier status for inherited conditions
Keep in mind
- You pay a premium for health data on top of ancestry
- Trait reports aren’t always accurate for everyone
Buy this if: you want both the relative finder and a broad health screening from one tube of spit.
Pass it up if: you only care about finding relatives and don’t want to pay extra for health reports.
6. 23andMe+ Premium Advanced Ancestry & Health
The maximum 23andMe experience, with a year of exclusive reports and 5,000 relatives to browse.
This is the premium tier of 23andMe, bundling the full Health + Ancestry service with a 1-year prepaid membership to the Premium reports. The headline feature for relative hunters is access to 5,000 DNA Relatives—a higher cap than the standard service allows—plus advanced filters to narrow down your matches faster. Reviewers point out the experience is effective for clear ancestry and basic health insights, while correctly noting it has limits and shouldn’t be treated as a medical test.
You get pharmacogenetics reports that explain how your body processes certain medications, Health Tracks for preventive monitoring, and Historical Matches that link your DNA to ancient figures. The ancestry side includes the full 4,500+ region breakdown, Haplogroups for maternal and paternal lines, and Neanderthal ancestry. A valid payment method is required at kit registration, even though the year is prepaid.
The considered take from owners is mixed on the premium add-on. Several note that the extra features are valuable, with one saying they found hereditary risks and drug sensitivities that their own doctor missed. Others suggest the Premium membership isn’t worth it if you’re only going to look at your results once and cancel. If you plan to explore for a full year, the value is there.
What the upgrade adds
- 5,000 DNA Relatives with advanced filters
- Pharmacogenetics reports on medication response
- A full year of access to exclusive reports
What to consider
- The Premium add-on isn’t worth it for one-time users
- Requires a valid payment method at registration
Splurge on this if: you want the most advanced ancestry and health reports and will explore them for the full year.
Stay basic if: you’ll check your results a few times and cancel—the standard kit is enough.
7. Choice DNA Full or Half Sibling Test
A targeted sibling test that skips the ancestry map and goes straight for the relationship answer.
This is a completely different kind of product from the big ancestry kits. It’s not about finding unknown relatives in a database; it’s about confirming whether two specific people are full or half siblings. The kit includes 4 swabs per person to ensure high-quality samples, and all lab fees are included in the price. Shoppers say it was very easy to use, the directions were clear, and the results came back even faster than expected.
Collection is a non-invasive cheek swab that’s suitable for adults and children alike, with no clinic visit required. The results are delivered by email, with one buyer reporting confirmation of their full sibling status in about two weeks after mailing the samples in. Customer service gets consistent praise for being helpful in explaining the results.
This isn’t a matching service, so don’t come here looking for a list of cousins. It’s the right tool when you already suspect a specific relationship and need scientific confirmation. The small review count means the experience isn’t as battle-tested as the big ancestry companies, and a few isolated voices report issues with receiving results, so it’s a smarter buy when you need a quick, specific answer.
Why this one’s useful
- Easy cheek swab, no needles or clinic visits
- 4 swabs per person for sample quality
- Results reported in as little as 2–6 days
What to expect
- Email-only results, no app interface
- Designed for a specific question, not broad matching
Order this if: you and a sibling need to confirm your relationship without a trip to a clinic.
Look elsewhere if: you’re trying to discover unknown relatives—this won’t find a match for you.
8. Genetrace DNA Cousin Test
A laser-focused cousin test that answers one specific question in a day or two.
When you’ve found a potential first cousin through a family tree but need confirmation, this is the tool. It’s designed to determine whether two individuals are biologically related as first cousins, especially useful when the alleged parent isn’t available for testing. The kit includes all lab and sample return fees for two potential cousins, with no hidden costs.
The labs run the samples twice in an AABB, ISO 17025 & CLIA accredited facility, analyzing up to 27 genetic markers for maximum accuracy. You get secure, confidential results within 1–2 business days after testing begins. Owners describe the experience as fast and easy, with one noting the test kit was exactly as shown and they were happy that a full profile was provided with the report.
There’s a real-world limit here: this test checks a specific relationship, not a broad family search. If you’re at the stage where you need a yes-or-no answer on an already-identified cousin, it’s perfect. One owner found it “very strong that we were not related,” confirming the test’s ability to rule out a connection. A small number of buyers report the results are hard to read, wishing for a simple yes or no in plain language.
What makes it work
- Secure results within 1–2 business days
- Up to 27 genetic markers analyzed
- Accredited lab runs tests twice
What to know first
- Only answers the first-cousin question, not broad matching
- Results can be hard for non-experts to interpret
Pick this if: you’ve already identified a likely cousin and want a fast, lab-grade confirmation.
Steer clear if: you need to discover unknown relatives—this won’t search a database for you.
Understanding the Specs
Relative Finder vs. Ethnicity Estimate
The relative finder is the tool that matches your DNA against everyone else in the company’s database to find people who share a common ancestor with you. The ethnicity estimate is the pie chart showing where your ancestors lived long ago. For finding living relatives, the relative finder is the feature that actually matters—it’s what tells you that a person with a specific name shares DNA with you.
Regional Detail (3,600+ vs. 4,500+)
Companies report how many geographic regions they can identify in your DNA. A test that covers over 3,600 regions can give you a broad continental breakdown, while one covering 4,500+ regions may pinpoint a specific valley or village your ancestors came from. More regions generally means more detail, but it has no effect on how many living relatives you’ll match with—that’s purely a function of database size.
