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. DNA Clinics do not offer free DNA testing. The service in the UK for establishing genetic biological relationships is predominantly carried out by the private sector. The NHS does not offer DNA testing for paternity or other relationships. Companies offering free DNA testing are falsely advertising the service. DNA Clinics provide the DNA test kit free of charge, with payment for the test due on return of your samples.
Hi, I’m just a bio major, but my genetics professor was just talking about this. These tests are not complete genome sequencing. They only look for SNPs (genetic markers) parts of the genome that tend to have a lot of variation. They determine your ansestry by comparing your markers to those of others in their database, but because their database is always expanding, the numbers change. Its still a good approximation and gets more accurate as more people take it, but if you want to be certain you have to have complete genome sequencing. There is a company called Nebula that does it. Hope that helps.
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.”
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.
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.
