A friend of mine knew I had been working on my family history and bought me an AncestryDNA kit for my birthday. My results were surprising to say the least. I discovered I’m 35% Native American, 5% African and 29% from the Iberian Peninsula. This has drastically broadened the way I think about my identity and heritage. I feel connected to those parts of the world now and I’m excited to see how far back our records can go.
This is another feature of these genetic-testing sites – they are littered with caveats and disclaimers, forever emphasising that they’re not actual “diagnostic tests” and, if you are really concerned by your results, to seek further advice from your GP or another health professional. As has been pointed out by McCartney, when anything looks serious, ultimately it’s back to the very GP and exact NHS infrastructure that these kits profess to smoothly bypass.
In addition to showing geographic ancestry percentages, some direct-to-consumer DNA tests also include insights about physical traits like hair and eye color. With 23andMe, this trait information is mostly available in the upgraded Ancestry + Health kit, but some interesting tidbits can be found in the Your DNA Family report, which is available if you opt to participate in the DNA Relatives service. This report tells you interesting information, such as that your DNA relatives are 32 percent more likely to own a cat or 11 percent less likely to have lived near a farm when they were young. DNA Passport by Humancode offers information about more than 20 physical traits, from appearance to grip strength. Ancestry DNA recently added its AncestryDNA Traits upgrade for $10, and it lets customers who have already taken one of its tests unlock information about 18 genetically influenced traits, including bitter taste perception, freckles and cilantro aversion.
Following a recent case in Phoenix, in which a patient who had been in a coma for nine years gave birth, Arizona lawmaker David Livingston sponsored a senate bill that would require certain occupations to submit DNA samples along with fingerprints for use by law enforcement. Though Senate Bill 1475 has been updated since its initial draft, it could set a precedent that normalizes collection of DNA samples from everyone, not just those suspected or charged with a violent crime. 
It could be that, in the main, genetic-testing kits such as these could, if promoted and used responsibly, end up zoned completely away from legitimate science and medicine and placed where perhaps they belong, firmly in the lifestyle-extra zone, if and when people think they’re “worth it”. Though, somewhat tellingly, when I ask Newman if he thinks that any of the genetic testing kits are worth buying, he instantly says: “No. I’d say, go to the cinema, watch some sport. Spend the money on something nice, something life-enhancing.”
If you wanted to learn about a specific side of your family, you must consider your genetic markers. A good example is if an individual wanted to know the origins of the African-American part of the family. Some luck would be required to retrieve this information. This person may be able to learn the percentage of genetic markers that favorably match certain regions of Africa. This is dependent on if different regions can be distinguished by the AIM’s. The most commonly used African AIM’s for determining African ancestry come from West Africa.
For our evaluations, we assembled a group of testers willing to spit into a tube on camera. We chose four individuals of varying backgrounds. Two had previously taken one or more DNA ancestry tests, and two had not. Two had fairly well-documented family histories to compare against, one was adopted, and one had information about one side of the family, but not the other. All of us took DNA tests from AncestryDNA, 23andMe, National Geographic and Family Tree DNA. One tester also took each of the five additional tests we reviewed. After collecting spit and cheek cells, we mailed all of the tests at the same time and waited for results, noting all communications from the company in the meantime and how long it took each service to notify us that results were ready to view. We collected data based on testers’ impressions of their results, each service’s features and extras, how easy it was to use and navigate the service’s website, along with several other factors. We added this testing data to rigorous research and information gleaned from conversations with representatives from Ancestry, 23andMe, MyHeritageDNA, LivingDNA, Humancode (now owned by Helix) and 24genetics. 
A few of the DNA tests we tested, including the National Geographic Geno 2.0, use genetic sequencing instead of genotyping. Sequencing is newer in the mainstream direct-to-consumer DNA testing market, as it used to cost more and take much longer to sequence a person’s DNA. Sequencing identifies the exact makeup of a certain piece of DNA – be it a short segment or the whole genome. The Helix tests sequence the Exome, which are the parts of the genome responsible for protein production, plus several other regions of interest. DNA sequencing gives more information overall and has more uses in medical testing than genotyping. In the future, more DNA kits may move from genotyping to DNA sequencing as the technology gets cheaper and faster, but for now both are effective ways to look into your geographic ancestry.
In our tests, we did find consistency across our results on the continental level. For example, my ancestry is exclusively East Asian, but 23andMe breaks it down into 80 percent Korean, 10.5 percent Japanese and 0.8 percent Chinese, with the remaining 8.7 percent in broader categories. However, Ancestry reports my DNA as 98 percent Korean and Northern Chinese, with only 2 percent Japanese. National Geographic places 85 percent of my ancestry from Northeastern Asia and 14 percent from the South China Sea region, with my DNA most closely matching the Korean and Japanese reference populations.
DNA Clinics will always advise an appointment for your DNA test. However, there are occasions and circumstances when our customers prefer to collect their own mouth swab samples for DNA testing. DNA Clinics self-collection DNA testing kits are available to order by telephone by calling 0800 988 7107 or on-line at www.homednapaternitytest.co.uk. DNA test kits ordered on-line are sent out for FREE. The payment for your chosen DNA test is payable when you return your samples to DNA Clinics.
If you are concerned about your data being sold, your concern may be valid. In the past, records have been sold and de-anonymized. It is possible for genetic information to be used to find the name of the individual the DNA came from. This can happen regardless of whether or not your name was in the database. This scenario has occurred in the past.

Haplogroups are a different story. Your maternal line haplogroup assignment is derived from a separate piece of DNA called the mitochondria. Since mitochondria is passed on only by mothers to their children, your maternal line haplogroup assignment only tells you about your mother's side of the family. Similarly, the paternal line haplogroup assignment is derived from a different, separate piece of DNA called the Y chromosome. The Y chromosome is only passed from fathers to sons and only traces the paternal line.
Although FamilyTreeDNA is the only DNA testing company openly working with law enforcement, other DNA companies don’t necessarily keep your DNA information private. Many direct-to-consumer DNA testing companies sell your data to third parties. For example, 23andMe shares customer data with pharmaceutical giant GlaxoSmithKline, which uses the information to develop medical treatments. In this case, you can opt out of having your DNA information used for research, and the data is shared only in aggregate.

While men can trace both their maternal haplogroup (from mitochondrial DNA) and their paternal haplogroup (through the Y chromosome passed down from their father), women can only trace their maternal haplogroup (through the mitochondrial DNA passed down from their mother). This is because the paternal haplogroup is traced through the Y chromosome, which women do not inherit.
Bill Newman, professor of translational genomic medicine in the Manchester centre for genomic medicine at the University of Manchester, and chair of the British Society of Genetic Medicine, says that such tests in this context simply don’t make sense and that, usually, telomere testing would only be used in in-depth studies of ageing and diseases associated with ageing. “There’s some really brilliant work going on, by some of the best biologists in the world,” says Newman, citing Elizabeth Blackburn, who won the 2009 Nobel prize for medicine for her work on telomeres. “But there’s no evidence whatsoever that measuring a person’s telomeres gives any indication about their health – or beauty, intelligence, or anything else that might be listed on these sites.”
