At the moment the four best places to test autosomal DNA in alphabetical order are 23andme, Ancestry.com, Family Tree DNA, and MyHeritage (good european records and trees).). New DNA testing companies, not yet reviewed by me are LivingDNA (best breakdown of ancestral locations in the British Isles).
If you test at Ancestry.com or 23andme or MyHeritage, you can take your results and upload them to Family Tree DNA to see your matches there for free plus get their full tools for a small price ($19). Whichever one you use, upload the results to GEDmatch.com in order to compare to people who have tested elsewhere as well as get some different ancestry composition results. You can benefit science and get some more information and another view of your ancestry composition by uploading your results to DNA.land (see my blog post about that site). MyHeritage.com is also taking DNA uploads of other companies’ test results.
Which DNA Test is Best?
I created a comparison table of the things I consider important for my recent DNA Basics talk. You can download it here Download and see the slide at http://slides.com/kittycooper/dna-basics#/29 – Since that chart was created Ancestry.com has increased in size to 9+ million testers! More than twice the size of the next largest.
The ISOGG wiki has an excellent article about DNA testing here:
Another detailed discussion of where to test is in Kelly Wheaton’s Beginner’s Guide lesson 2 at https://sites.google.com/site/wheatonsurname/beginners-guide-to-genetic-genealogy/lesson-two-which-dna-test
And Roberta Estes goes into even more detail in her comparisons at https://dna-explained.com/2017/04/24/which-dna-test-is-best/
My Advice on Where to Test
Unless you want to join a specific surname project or have mainly non-USA ancestors, I recommend that you test at Ancestry.com – which is best for the non-serious genetic genealogist because of its tree matching and interesting presentation of your historic ancestry. If your ancestors are British, LivingDNA has the best breakdown of which area of Britain they are from but they do not have cousin matching yet. If your ancestors are recently non-American, then use 23andme which has the largest non-USA database. MyHeritage and FamilyTreeDNA also have many foreign testers, but very few Germans have tested at all and those few are at Family Tree DNA. Use Family Tree DNA or MyHeritage for older family members since the cheek swab is easiest for them, note that Family Tree DNA saves the physical DNA for up to 25 years so more tests can be done on them.
Additionally perhaps get your Y STRs tested at Family Tree DNA if you are male and interested in your paternal line. Whichever testing company you choose, you can then upload your raw data to GEDmatch.com, DNA.land, and MyHeritage.com to find matches from other testing services who have also uploaded to those sites. LivingDNA is also accepting uploads but they will not have results until next summer.
Here are the details about each company in alphabetical order.
- Twice the price of the others (currently $199) but only $99 if you skip the health part.
- Best ancestry composition of the three.
- Gives you health related information about your genes.
- Has easy to use tools for looking at the data
- Many of the people who have tested there are not interested in genealogy and will not respond to queries and invites, n.b. you cannot look at where you overlap people you are not sharing with unless you and they have selected “open sharing”
- Tests SNPs on the Y chromosome which gives you your haplogroup (you also get your mtDNA haplogroup)
- Has the second largest database and the most international customers (lots of Norwegians, very few Germans).
- Connects you to those shaky leaves and thus often does the work of searching your cousin’s tree for you (see http://blog.kittycooper.com/2014/08/in-defense-of-ancestry-coms-dna-offering/ for an example)
- Best for those with colonial ancestry
- By far the largest database and getting larger every day because of all the folks with family trees there.
- You cannot do chromosome comparisons with other testers there so you have to load your data to FamilyTreeDNA or GEDmatch or DNA.land for that.
- No tools for looking at the raw data
- Wonderful automated tree matching for your DNA matches which can be used with private mirror trees to help adoptee searches.
- Most privacy, best for your worried about their DNA being used for drug studies, etc relatives
- Can compare yourself to anyone you match, so better for adoptees than 23andme.
- Easy to look at matches but tools not as good as 23andme (cannot compare your matches to each other)
- Has many surname and geographic projects: Norway – Scandinavia Y – Germany mtDNA
- Connects to the world family tree at GENI.com (see my post on DNA at GENI)
- If you buy your test through a project you may get a discount.
- Has the smallest database of autosomally tested people but presumably they are all interested in genealogy
- Has many Jewish testers and includes Sephardic jewish ancestry composition unlike any of the others.
- Commits to storing your DNA for at least 25 years; thus additional tests can be run on it.
- Uses a cheek swab to collect the DNA, rather than spit, which the other two use, so better for old folk.
- Can test STRs on the Y chromosome which are more useful for recent genealogy, for surname research (father’s father’s father’s etc line), but this is a separate test from the family finder test.
- For deeper ancestry, more detailed mtDNA testing is available here (again a separate test) which is the mother’s mother’s mother’s etc line
- Best price, currently $79
If what you want to know is your deeper ethnic roots consider the nat GEO genome 2.0 project
If you want detailed health results and can afford it, try GENOS at $499 which claims to sequence your entire exome, thus 50 times more SNPs than the genealogy focused companies listed above.
