Your review of the various testing companies is misleading and incomplete. The only test that can give information about recent relatives ( 5 generations back only) is the autosomal test. The others only give our ‘deep’ roots out of Africa migration thousands of years ago. But for the autosomal test to provide us names with whom we can contact, we have to give permission to have our email and name listed (and of course so do others). The tests that say we are such-and-such % of this or that ethnicity isn’t very accurate because, keep in mind, the wars and the spoils of wars that humans have been engaged in forever, mean we all have a mixture of genetic material from around the world. I can tell that the author(s) of this review did not really understand what these tests are about.
In this case, I would recommend two options: 1. Ancestry.com – If you choose to take their DNA test, you can also take advantage of their family tree feature. Your DNA test results would be compared to other samples in the database. Combining this, with a manual lookup you can do, you might trace relatives on your father’s lineage. 2.LivingDNA – LivingDNA provides a separate unique analysis of the paternal lineage. This analysis will give you an in-depth picture of your father’s heritage. The only drawback is that LivingDNA database is relatively small (compared to ancestery.com and other big competitors). You can bridge that gap using GEDMatch service, by uploading your raw DNA data (acquired by LivingDNA). You can read more about GEDMatch here. Good luck and I hope you would find what you are looking for!
Otherwise, the home-testing kits could be said to fit in with our increasingly health-conscious and, if you wish to be cynical, narcissistic times. What says you’re “special” more than finding out everything about yourself, right down to the nitty-gritty of genetics? In this way, these kits could be viewed as the latest plaything of the “worried well”. You could see how the scientific approach would appeal to the health-obsessed of all sexes and ages, your marathon runners and serious gym-goers, who take their fitness extremely seriously.
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.
If this individual used several different companies for DNA testing, they might get an idea as to their past origins based on the moderate or high similarities of the people currently living in different regions throughout Africa. This is only possible if the companies have established the correct reference populations. This person must understand their DNA is being matched to the current population as opposed to the people who occupied the region hundreds of years in the past. It is just as possible the results would state this African-American individual is 75 percent European. This is because the ancestry markers chosen are only for a small percentage of this individual’s DNA. The African population has a more genetic diversity in itself than a European population and an African population.
Even the cousin matches seem to be based on the surnames listed in your tree with no attempt at comparing the people between trees to see if there is actually anyone in common! I have managed to find a few actual matches in the cousin match list, no thanks to their matching service, but more to the fact that I have been researching my tree for many years and am fortunate to know someone who is very competent at DNA and family tree research to help me weed out the rubbish from the genuine matches.
There are two questions I would want answered through DNA testing. I never knew my mother but was told my great grandfather was “full blooded Cherokee Indian” and my six year old grandson is told by father “he is direct descendent of the Zulu nation”. Their words! Which DNA testing company would be able to answer these questions? I’m a little confused with the info presented. Thank you!
Once your genetic information is out there, it’s difficult to undo. Also, once you know something about yourself, it’s impossible to un-know. Revelations such as having different parents than you expected or finding unknown half-siblings are difficult to process at any age, but it’s particularly troubling for kids. However, you can always simply opt out of family matching features.
So from that perspective, if DNA testing for fun and to find potential cousin matches is something you are considering, then wait for when they have a cheap special offer available. If you want a proper ethnic breakdown, either use the raw DNA file and upload it elsewhere or use one of the more accurate providers. Note they only do autosumnal DNA testing and NOT Y-DNA testing so you will need to use another service for that.
To prepare to take a cheek swab sample, you also have to refrain from eating for about an hour before. Swab kits generally contain more components, including one or two swabs and containers to protect the used swabs from contamination. We found it easiest to organize all the pieces first, to prevent any fumbling with a sample collection swab in hand. Some cheek cell kits put a stabilizing liquid in the sample containers, which required extra caution to prevent spilling.
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.
EasyDNA specialises in paternity testing. Results provide 100% accuracy if the male tested is not the biological father of the child and a 99.99% probability if he is the biological. We also offer a wide range other tests including DNA Profiles, DNA Art, Twin Zygosity DNA Testing, Forensic DNA Testing, Genetic Predisposition Test and Ancestry DNA Testing. Our many relationship tests will help determine whether alleged relatives, such as siblings or grandparents and their grandchildren, are truly biologically related.
Which is all very well, but do these kits work and deliver the service they promise and what about the wider ethics and implications of home genetic testing? Is it always wise for generally under-informed, under-prepared consumers to meddle in the highly complex, nuanced arena of genetics, risking confusion, complacency or even outright panic and anxiety when confronted with ostensible “bad news” (which may not even be true)?
