If you have the Health + Ancestry Service you have access to the full 23andMe experience. If you only have the Ancestry Service, you can easily upgrade to the Health + Ancestry Service for £90 which gives you access to all 125+ reports on ancestry, traits and health. You are eligible to upgrade once you have received your Ancestry reports. To upgrade, log in to your 23andMe account and navigate to the Settings page. You will receive immediate access to your new health reports.

Our testers took multiple DNA ancestry tests, and the services returned slightly different results for each person. This doesn’t necessarily mean that any one company is more accurate than another. Every DNA testing service uses its own algorithm and data set – different reference populations drawn from different databases. 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.”
There are many places you can upload your raw DNA, and several of them are free. Popular third-party DNA analysis tools include GEDmatch and Promethese. GEDmatch is a free, open database and genealogy site that gives additional DNA relative matching and trait results. This tool has information from users of multiple different testing companies. Promethease compares your raw DNA information against scientific reports that link certain markers to health conditions, though you should take these results with a grain of salt as genetic links do not equal a diagnosis.
Newman says that there’s a basic lack of “literacy” and understanding about genetic testing, among the public and even other health professionals. People are given false reassurances or made to panic (just because you have certain genetic variants, it doesn’t mean that you will develop a particular condition). Newman also makes the point that, in his field, counselling happens before and after testing and, while people with cancer or heart issues nearly always opt to have the test (as they can then take action to varying degrees), often people with conditions such as Huntington’s disease in their family decide not to go ahead because a diagnosis would change nothing for them. In any event, Newman says that, with genetic testing, while there are different levels, intensive counselling is always “absolutely key”.
All this comes into sharp focus with the comprehensive kits such as the one provided by 23andMe: the one I drool into a tube for (incidentally, 23andMe doesn’t test for Huntington’s disease). Most people, like myself, have a low understanding of genetic variants, what phrases such as “higher risk” or “probability” actually mean or how to interpret our results correctly. Is it right that ordinary members of the public must navigate potentially frightening and/or misleading results alone?
Each of the kits work similarly: You answer a few questions about yourself, order the kit, collect your sample, register the kit (this is very important), send it back, and wait for the results. That said, they differ in the collection process and, to a smaller extent, the cost of shipping. When we tested 23andMe back in mid-2015, the company was unable to accept DNA samples collected in or sent from New York State, because of local laws (we had to cross the border to New Jersey). The company was also prohibited from shipping DNA kits to Maryland.
Who knows how much of it made solid scientific sense? However, I have to confess that I rather enjoyed it on the level of an indulgent genome-oriented “pampering session”, just as I had a hoot with the ancestry/Neanderthal/earlobe data on 23andMe. Where Thriva is concerned, I also noted that it did advanced thyroid tests. Although such tests are available from the NHS, I’m hypothyroid myself and I know that sometimes it can be difficult and time-consuming getting tests repeated and it could be useful to be privately tested in this way.
It’s easy to do these tests; it’s usually just a case of collecting your own samples at home, filling in short, basic questionnaires, posting the packages, and then logging on to interactive websites for confidential results (all the kits I tested used outside laboratories). With an array of price ranges and options, from one-off DNA-blitzes to targeting specific health areas, to fitness/wellness tracking, it’s no surprise that these kits are proving to be very big business and the field is primed to get even bigger, with a global market estimated to be worth around £7.7bn by 2022.
