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.
Note that DNA testing isn't the only kind of kit that collects physical evidence from you these days. Ubiome is one noteworthy example. The service evaluates your microbiome—basically the bacteria that live in and on you. In our review, we took its gut biome test, which required our intrepid reviewer to send in a poop sample (insert poop emoji here).
An ancestry DNA test uses a saliva sample to determine which areas of the world your DNA can be traced back to. DNA kits have become very popular during the last few years. This has led to many people having numerous questions. You may be wondering if your genetic information will be used for research or sold and how this impacts your privacy. You may also be concerned regarding the accuracy of this test or have numerous additional questions. The first thing you must realize is the question of your DNA is complex and there may not be a simple answer. The majority of people in the world have DNA from numerous different regions. You may perceive this combination as unique or you may see it is odd. Either way, you need to be open and prepared for a surprise.
Most direct-to-consumer DNA test companies warn that the tests may reveal things you wish you didn’t know about your family. For example, you could find out that one of the people who raised you isn’t your biological parent or that there’s an entire branch of your family you didn’t know about. There isn’t a way to prepare for a shock like that, but you can opt out of a company’s family-matching services if you’d rather not know.
Health & Wellness tests: There are a ton of health and wellness DNA tests. We found several specifically oriented to dieting and weight loss, including embodyDNA, Vitagene, DNAFit and the several options available through the Helix marketplace. While there definitely are some links between DNA and factors that contribute to weight, we advise taking these diet plans with a grain of salt, as DNA science is still a relatively young field. We similarly advise caution for the multitude of non-diet health and wellness DNA tests, which offer insights into your sleep, food sensitivities, and vitamin and mineral levels. And double that for medical information found in consumer DNA kit test results. While medical insights learned from taking an at-home DNA test may be interesting, it’s best not to take them too seriously. If you have a concern about a genetic predisposition to a disease, it’s best to talk to your doctor instead of relying on a direct-to-consumer kit.
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.
Uploading my Raw AncestryDNA file to the free GedMatch service, immediately displayed my known Italian, Scottish, Welsh and English heritage along with French that I had been hoping to find to confirm a verbal family history plus Irish, German and Swedish which were a pleasant surprise that I will enjoy trying to discover which branch of the tree they belong to! I have also uploaded the DNA file to other free services, MyHeritage that also shows the Mediterranean connection along with LivingDNA whose results I am still waiting for. All these services also include cousin matches who share dna so you end up with a much bigger pool of possible matches than Ancestry alone.
More controversially, some of these kits profess to tell you your biological (as opposed to actual age) by measuring the length of your telomeres (in basic terms, the caps at the end of each strand of DNA that protect chromosomes, like plastic tips at the end of shoelaces). Other tests, such as 23andMe, predict higher risks of developing serious conditions, such as multiple sclerosis, Alzheimer’s and Parkinson’s, including the test for BRCA1/BRCA2 (breast and ovarian cancer) that Angelina Jolie famously underwent, going on to have a preventative double mastectomy and surgery to remove her ovaries.
