There's a lot you can learn from a DNA test. In addition to deepening your understanding of ancestry, some services will introduce you to relatives around the world or shed light on your predisposition to specific health issues and diseases. Here we present to you our roundup of the nine top DNA testing kits and services -- what they offer, how they work and how much they cost. 
For better ancestry and medical insights, you should encourage family members, especially parents and grandparents, to take a DNA test as well. If your family is from a specific geographical location for generations, your samples could potentially improve the service's reference panel, in turn improving results for everyone. If you’re female and take a test from 23andMe or LivingDNA, you can view paternal haplogroup information, and you get more information when one of your male family members takes a test as well.
Starting at $79, the company's DNA test kit is competitively priced and covers the basics: A simple cheek swab will give you an analysis of your ethnic origins and the identification of relatives who share your DNA. In addition to MyHeritage's free basic subscription, which will let you assemble a family tree up to 250 people, there are other packages that accommodate larger trees, advanced DNA features, and more robust research tools. The company allows you to upload test data from other companies.
My grandfather was adopted, my father’s father. I have found FamilyTreeDna (FTDNA) was the best when it came to test results. Ancestry was great for research. I tested with both. They say fish in all of the pools and I have. I highly recommend testing with both Ancestry and FTDNA. I found my great grandfather who was born in 1884. 23andme was no help at all. MyHeritage works with FamilyTreeDna (FTDNA). HOPE THIS HELPS. Gary
G6PD deficiency is a common genetic condition caused by defects in an enzyme called glucose-6-phosphate dehydrogenase, or G6PD. The G6PD enzyme helps protect red blood cells from damage. In people with G6PD deficiency, red blood cells are destroyed upon exposure to certain environmental triggers, which can lead to episodes of anemia. This test includes the most common variant linked to G6PD deficiency in people of African descent.
If you opt in to 23andMe’s family matching feature, you can connect with other 23andMe users with similar genes. This feature lets you view your matched relative’s display name, sex, profile photo, percent of DNA shared, number of DNA segments shared, relatives in common and haplogroups. The interface also estimates how closely you are related to each match. It’s very easy to connect with your matches on the website, and you can request more information by inviting them to share DNA reports.

Is this a perfect method?  No, but it’s a good way to get a general idea about where your ancestors were from.  Genealogical DNA tests can tell you a lot about your ancestry going back 300-500 years in time, for the most part.  They can also tell you a little bit about your ancestry going even further back.  This is why comparing your DNA to those whose families have stayed in a particular area for a long time is a fairly accurate way to perform the estimate.

The little changes are where “mutations” occur over generations – these aren’t necessarily bad, it just means that the gene has been copied slightly differently as it passed from father to son. Because its possible to predict how often mutations are likely to occur, comparing the Y-DNA from distant male cousins with a common ancestor (and seeing how many differences there are in a standardised set of markers tested) allows a rough estimate of when that common ancestor might have lived. A very close match between two men who share a common surname (only one or two differences) makes it very likely they are related, and a bigger number of differences makes it either less likely they are related, or that the most recent common ancestor is very many generations back.
And that’s where it starts getting interesting, because then we can start comparing that genetic signature to the results from other men who share the same surname but don’t appear on our family tree. If the matches are close, then we can start thinking “is there a common ancestor for these families another generation or two back? Are the families linked in some way?”. Depending on what we already know about either family group, it can help target the paper research to get those families linked, or take us back another generation or two.
The DNA tests we reviewed either require a saliva or cheek cell sample. Saliva-collecting kits include a tube that’s marked with a fill line and sample number. The tube often has a liquid-filled cap with a stabilizer that acts as a preservative to protect your DNA from degradation during transport. Cheek swab sample kits include one or two swabs for scraping the insides of your cheeks for 30 seconds to a minute to collect cheek cells and some sort of container to place the used swabs into after collection. This prevents contamination. Our testers found upsides to both types of kits but generally preferred saliva collection kits, even though they took longer.
Some concerns about the ultimate efficacy of certain home tests seem to emanate from the industry itself. I did a telomere-measuring test (a mouth swab) by Titanovo, based in north Colorado, which came back saying that my telomeres were too short, putting me at 10 biological years older than I am. However, when I contacted Titanovo, it explained that it had stopped telomere measuring and was now concentrating exclusively on its DNA-utilising “bioinformatics” health, fitness and wellbeing website (analysing client data from other genetic testing sites).
A collaboration between scientists, researchers and genetic experts from across the globe, Living DNA has offered ancestry tests since 2016 while parent company, DNA Worldwide Group, has been operating since 2004. Our focus has always been on providing the world’s best collection of British and Irish historical records and while we’ve investigated the DNA market for some time, we hadn’t identified a partner that could truly bridge the gap between genetic genealogy and traditional family history research. Living DNA’s focus on British and Irish DNA makes them our perfect partner.
Each sentence tells a cell to make a special molecule called a protein. These proteins control everything in a cell. In this way, DNA is like the boss of a company, and not the brain of the cell. It issues instructions, but doesn't do very much of the actual work :) These proteins help each cell do its job. Each gene makes one protein, and only one protein.

The results of mixed DNA profiles may therefore provide reduced match probabilities when compared with non-mixed profiles. It may be possible for a scientist to be able to assess the relative amount of DNA contributed by different donors in a DNA mixture. If one person has contributed a clear and distinct majority of the DNA detected, that part of the profile may be referred to as the “Major Contribution”.


When you get your 23andMe results, it takes you to an easy-to-navigate dashboard with your ancestry composition report front and center. Testers reported both high levels of confidence in the accuracy and high rates of satisfaction with the contents and detail of their results. The service breaks down the world into 171 populations, based off its reference panel of 10,000 individuals with known ancestry. Some of these population groups are a tad redundant. For example, I received hits for South Korean, Korean, Broadly Japanese & Korean, and Broadly East Asian in my report, which all represent a similar area but show different levels of certainty. Scrolling down your ancestry summary, you can also view your ancestry timeline. This estimates how many generations back your most recent ancestor from each of your matched regions probably lived. You can also view your ancestry composition mapped out on chromosomes. This view is interesting, as you can change the level of confidence from speculative to conservative, which equates a match percentage of 50 to 90 percent.
I used 23&me, (who has around 80 geographical regions) and while I was disappointed with the nationality results, it was only because I thought they were a bit vague – but in all honesty, I didn’t really know what to expect, so there’s that. Now understanding a little more about the limitations of results from any company, have no problem with what I received.
If you want to keep things really simple then we recommend 23andMe as it offers the best all-round DNA testing kit. It offers a mix of everything including family matching, ancestry percentages and optional heath insights. If you’re more interested in your genealogy then the AncestryDNA kit provides more detail along a gene pool and family tree. The National Geographic Geno 2.0 DNA kit is the best kit for connecting your genes to history going back up to 100,000 years.

In Newman’s view, the genie is out of the bottle with home genetic-testing kits. He says that while the kits could potentially provide data in the future, right now, they lack “clinical utility” – they look at genetic variants that, individually, have a very low chance of predicting specific health risks, as there are too many variables: “It’s like the Opportunity Knocks clap-o-meter, with some people further along the scale, and therefore more likely to get the condition and then people at the other end of the scale, who are unlikely to get it.”
I’ve had the same experience, and so have many others. My mother’s family is all from Italy, and yet my results came back with NO Italian whatsoever. Another said there was. None of them report German as a result, which is quite strange since Germans are definitely a people! These DNA tests are subjective and based on human analysis. As we all know, humans make mistakes. At the end of it all, I’ve decided that I’ll just stick with the ancestry my grandparents told me about when they were alive.
The spit is for one of the home genetic-testing kits I’m sampling. A growing number of these kits (brands such as 23andMe, DNAFit, Thriva, MyHeritage DNA, and Orig3n) promise to unlock the mystery of your genomes, variously explaining everything from ancestry, residual Neanderthal variants, “bioinformatics” for fitness, weight loss and skincare, to more random genetic predispositions, denoting, say, the dimensions of your earlobes or the consistency of your earwax.
TTR-related hereditary amyloidosis is often managed by treating the symptoms through medications or surgical intervention. However, some recently approved medications work by decreasing the production of the TTR protein, which makes it less likely to build up in the body's tissues and organs. In addition, most of the TTR protein is produced in the liver, and liver transplants have been beneficial for some patients. Scientists are currently working on other treatment options for this condition.
If you are interested in doing in-depth analysis, the firm offers a chromosome browser, allows raw data to be uploaded, provides support for setting different segment matching thresholds, and allows up to five comparisons to be done at once. Family Tree DNA allows trial transfers from 23andMe and AncestryDNA into its match database; additional transfers of various datasets is available for a fee. The company promises to keep data for 25 years.

Instead, MyHeritage DNA reported I that I’m of Japanese, Chinese and Vietnamese, and Mongolian descent. As I was looking for a reason to explain the discrepancy between tests, I discovered that there are large swaths of the map not covered by any of the service’s ancestral regions. The Korean peninsula is one of those areas, as are southern regions in South America, Africa and almost all of Australia and Russia. The oversight seems odd because MyHeritage could have easily included these missed areas inside a larger, generalized region instead of completely omitting them.
AncestryDNA, 23andMe, HomeDNA, Living DNA, and MyHeritage DNA all provide reports of your ethnicity, some showing maps of where your ancestors lived along with information about the particular countries and regions. National Geographic goes further back, pinpointing where in Africa your ancestors came from and tracing migration patterns through to near-present times. It's less about your personal genetic makeup and more about who your ancestors were and how you're connected to the beginning of civilization.
Finally, if you happen to meet a special someone on DNA Romance and want to see what your future child together might look like, there’s BabyGlimpse by HumanCode. Like a very advanced Punnett square, BabyGlimpse compares your and your partner’s DNA to create a profile that examines which traits your offspring might inherit, including things like ancestral DNA, eye color and lactose intolerance.
Finding small percentages of unexpected ethnicities may prove to be inaccurate upon further examination, and NOT finding traces of a certain group, such as Native American, may not necessarily prove that you do not have ancestors from that region or group. You can read more about that as it pertains to Native American research here. You can apply this statement to any ethnicity or region you might expect or hope to find in your results.
We evaluated each kit by ordering one, just like any customer would, and tracking how long it took to arrive at the lab and to get processed. Then we compared the breadth and depth of the results to see what rose to the top. The whole process was a lot of fun, in part because of the anticipation of getting the results. Most of the kits warn that testing your DNA can lead to surprising—even life-changing—results. For example, there's the story of a woman who thought she was Irish, but her DNA test revealed she was also European Jewish, Middle Eastern and Eastern European. After diligent research, she discovered that her father, who had died years earlier, had been switched at birth with another child.

Rachel, it’s been a year since you posted your query. Perhaps you have your answers? In case not, here are a few suggestions. Since you are an adoptee, perhaps with no knowledge of your biological family, you probably are most interested in details there, while your ethnic makeup is a very minor concern and where most DNA services give similar results anyways. Maybe your goal is to locate your birth parents? If that’s all true, then buy an AncestryDNA kit, as they have 10 million DNA profiles in their database, which is more than all competitors combined. The more profiles to DNA match against the more matches you’ll get to your biological relatives. Next download your raw Ancestry DNA data, and then upload it for free into MyHeritage (2.5 million DNA profiles), FamilyTreeDNA (1 million DNA profiles), GEDmatch (1 million DNA profiles), LivingDNA (unknown database size), and DNA.land (0.15 million DNA profiles). That’s almost 5 million more DNA profiles to match against. Combined with AncestryDNA that’s about 15 million profiles. If lucky you may match to a 2nd cousin or closer relative which with luck could lead to your birth parents, definitely will match to a few if not many 3rd cousins and 1000s of 4th or more distant cousins. If you change your mind and decide purchasing a second DNA kit is worth the expense, then buy a 23andMe DNA kit, which adds 5 million more DNA profiles to match against. Hope these suggestions were useful. Good luck.
Generally speaking, those people who have tested with FTDNA, AncestryDNA or MyHeritage DNA have done so for genealogical purposes (even if it is only curiosity about their family’s past) so the response rate from contacted matches is fairly decent. Oftentimes matches are open to being contacted by relations and are eager to compare trees. This is, of course, not always the case, but we have found it to be true for the most part.

It is very important that you take the time to read the privacy policy, terms and conditions and consent forms associated with any DNA test you take or any site you choose to upload your data to. While FTDNA has a proven track record of protecting the privacy of its users, there have been serious concerns over how AncestryDNA and 23andMe have used data in the past, as well as how they may use or sell your data in the future. Please read this article from Roberta Estes for more information on this issue. MyHeritage states that their consent form (that would allow sharing or selling of your results in aggregated data) is optional.  You can read more about that on The Legal Genealogist, who compliments MyHeritage DNA on their policy and openness.
Nacho Esteban of 24Genetics told us, “Ancestry is not an exact science. The top five companies in the world would show very similar results when talking about continents; the similarity is smaller when talking about countries. In regional ancestry, some border regions are difficult to identify and sometimes there may be discrepancies. So we cannot take the information as something 100% sure. But at the end, it gives a great picture of where our ancestors were from.”

Some ethnicity DNA tests will report on the percentage of your autosomal DNA that can be linked to Neanderthals and/or Denisovans – these are non-human ‘hominin’ species that inter-mixed with humans before dying out tens of thousands of years ago. The percentage of our DNA that originates from hominins is 1-5% and it varies greatly between individuals. Only a few genetic ancestry companies include this analysis in their tests (e.g. 23andMe and National Geographic’s ‘Geno 2.0’) and it can be fun to see how much of these ancient species still live on in your genetic code.
The first kit I try is Thriva’s baseline test (£49), which, like all its products, checks your blood. The box arrives promptly enough (containing spring-loaded needles, a little collection tube, antiseptic wipes, plasters, etc), but there’s a problem. The idea is to prick your finger and massage blood into the tube, but I just end up making my fingers sore and what I get out barely smears the top of the phial. Maybe it’s just me, but it turns into a right faff. In the end, I take advantage of Thriva’s service to send someone out to take a sample of blood from my arm.
A DNA profile can also be adapted to produce artwork. Several companies will use the profiling technique discussed above, but they’ll combine florescent colours with your genetic markers to produce bands that look a bit like a barcode. These bands can be mounted on canvas, wood, metal or other materials to create a piece of art that can be displayed in your home. They can also be digitised and customised with different colours or background themes to make a range of ‘DNA portraits’. One company, Dot One, even makes scarves and rugs inspired by these patterns!
In testing, we found that many tests have much more specific and detailed results for European ancestry than anywhere else. This is due more to the diversity of the database than size. For example, AncestryDNA has the largest database with over 10 million samples yet results for Asian ancestry are markedly less specific than results from several companies with much smaller databases, including 23andMe and Living DNA.
When STR profiling is carried out, the whole of the person’s DNA is not examined. Rather, specific regions (loci) of the DNA which are known to vary greatly between individuals are examined. These loci are areas of the DNA which contain varying numbers of repeating sequences known as short tandem repeats (STRs). It is the number of these repeating units which can differ between individuals. If there are differences between profiles obtained from different samples, the two samples cannot have come from the same person. If, however, the profiles match, then it follows that the samples could have originated from the same person or from any other person who happened to have the same STR profile.Â
