Then comes the section about serious genetic variants. So far as “counselling” goes, previously, I’d waved away concern for my psychological welfare from the Observer’s science editor (“I’m a former goth,” I said. “My default setting is ‘doomed’”), but it turns out to be quite daunting. It doesn’t help that I initially mistake the full list of potential conditions for my own results, hence (thankfully briefly) thinking that I have higher risk factors for everything going. It makes me wonder – how many other people are going to do that?
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.
I am not sure how Ancestry get their results. Mine is 49% British and 49% German. This means one of my parents must have been British and the other German. I moved to the UK 15 years ago. But both my parents where German as where my 4 grandparents and my 8 great-grandparents. It seems to me they have rolled the dice and assumed that if you send a sample from the UK you must have British ancestry. No science behind it at all. I could have gone to the oracle at the fun fair.
A. As stated above, the NHS in the UK does not offer genetic testing for establishing biological relationships. Here at DNA Clinics, we pride ourselves on the clinical and ethical approach we provide for our DNA testing service. DNA Clinics may consider offering free DNA testing to individuals or families who consent to having their 'story' and experience of the DNA testing process published or reported in the media. This will only be considered for appropriate situations. Please call 0800 988 7107 for further information.
Whether it’s an autosomal test, a Y-DNA test or an mtDNA test, virtually all providers use the same science. Some providers offer an ‘off the peg’ solution such as Ancestral Origins™ or AncestrybyDNA™, so if you’re interested in these you should shop around for the lowest price. Most providers offer a test that interprets and presents the results in a unique way, so if one of these catches your eye, look for examples of how the results are presented on their website before you buy.
