Thank you for this webpage! It is very insightful. I wish I had found it earlier. I did the DNA test through 23andMe, a doctor’s office already had me DNA checked for health (Medical DNA Labs in Tampa, Florida). I am wanting to know more about my genealogy and the report I received from 23andMe shows most concentration from the British Isles so now I will probably do ancestry and maybe Living DNA. You did a fine job in explaining everything, again thanks!
Similarly, mitochondrial DNA, or mtDNA, is used by direct-to-consumer DNA tests to trace your direct maternal lineage and determine maternal haplogroups. While most DNA lives in your cells' nuclei, mtDNA lives in the mitochondria. Mitochondria are the cells' powerhouses – their 37 genes are necessary for cellular energy production and respiration. Previous research suggested that mtDNA is inherited directly from your mother, but a recent study found that biparental mtDNA may be more common. This discovery may affect maternal haplogroup testing in DNA tests in the future, but for now, it’s safe to assume your results are correct.
The 100,000 Genomes Project is an NHS initiative, run by Genomics England, and is the largest national genome sequencing project in the world. On entering, patients have their entire genome, of more than 3bn base pairs, sequenced. This is different from commercially available genetic testing kits, such as those from 23andMe, which only look at very small stretches of DNA in a process called genotyping. The hope of the NHS is that having so much genetic information, from so many different people, will allow “groundbreaking discoveries about how diseases work, who could be susceptible to them, how we can treat them, and what treatments might work”.

In fairness to 23andME, it leaves it up to the customer to unlock the more serious results – or not. When I unlock mine, I discover that, while I’m not genetically predisposed to such things as the BRAC1 or BRAC2 variant, Parkinson’s or MS, I have one of the variants for late-onset (mid-80s) Alzheimer’s. However, I don’t have any other markers for Alzheimer’s or family history or conditions associated with it or anything else listed in the rather lengthy disclaimer, which also stresses that it’s not a diagnostic result and to seek further advice from your GP if you are concerned.
When my results appear, they show nothing bad. If anything, it’s anticlimactic: cholesterol, vitamins, liver proteins and the like are all in the normal range, with only ferritin (iron stores) slightly high, with a recommendation to go easy on any iron supplements. My problem with the baseline test is that, unlike Thriva’s other products, clients are supposed to have one every three months to keep track, but would I really want (or indeed need) to do such a test so regularly?
If the company responsible for running your test is sold, whatever you signed loses significance due to the privacy policies of the company. Despite most of these privacy policies stating they will notify you of any changes, you would have to keep in constant contact with the company to ensure you were actually aware of these changes. The people willing to do this would be far and few between. Unfortunately, even if your name is not located within the database, this does not mean other databases cannot be used to determine your identity. In one specific case, a woman had a DNA test run. She found out she had a half-sibling. Although she was very excited about this news, this type of information would devastate numerous individuals.
While men can trace both their maternal haplogroup (from mitochondrial DNA) and their paternal haplogroup (through the Y chromosome passed down from their father), women can only trace their maternal haplogroup (through the mitochondrial DNA passed down from their mother). This is because the paternal haplogroup is traced through the Y chromosome, which women do not inherit.
So I get my DNA result and it has even less information than what my address can tell about me. They say they don't have have much information on the area am from. But that's not something they tell you when you buy. Furthermore half the information is incorrect. Called customer services and the answer is - Sorry you feel that way, nothing we can do. DO NOT SPEND YOUR MONEY HERE. MIGHT AS WELL BURN IT!!!

Looking at your raw DNA file might not give you any useful information unless you’re looking for a specific marker. You can also upload the file into a third-party DNA databases for information or results beyond what’s available from your testing company. This process is not without risks, as your DNA testing company only ensures the security of your personal information in its own environment. Once you download the file, you’re responsible for the file’s security. However, uploading your raw DNA to a third party database isn’t inherently unsafe — just be cautious.

Next, you'll receive an email alert that your results are ready, and that's when the fun begins. Your results may not be as dramatic as those portrayed in TV ads, but you may find some surprises. One important note: Results are different for women and men. Women, who have the XX chromosome, can only trace back the maternal line. Men, having the XY chromosome, can track back the maternal and paternal line, painting a complete picture. If you're a woman, it's worth asking your brother, if you have one, to take a test and share the results. When some of these services ask for your sex when you order your kit, they simply want to know about your chromosomes.


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.
If you opt in to DNA Relatives, you will be able to send and receive invitations to connect with other customers who share DNA with you. You can choose whether to respond to these invitations or not, and your DNA relatives have the same choice. We cannot guarantee that they will respond to your sharing invitations or messages. Regardless of whether you both agree to share, you will be able to see their birthplace, locations of their ancestors and surnames, if they have chosen to add this information to their profile. If you both accept sharing invitations, you will be able to see ancestry reports and overlapping chromosome segments.
Gteat article! Thank you so much. I am Jewish American. Both sides of my family immigrated from Eastern Europe/Russia about 5 generations ago. I would really like to try and find out more about exactly where they came from, identify potential living and deceased distant relatives in the USA and abroad and ultimately start creating an extensive family tree. Which test would you suggest?
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.
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”.
If you’re already using a specific geneology program, use their DNA test. I used My Heritage while I was using Ancestry for my family tree. I got called by a high pressure salesman to sign up for the My Heritage geneology program. (I had uploaded my gedcom to the My Heritage site.) I told him that I couldn’t afford two geneology sites. The guy was snotty and condescending. We figure we just wasted our money with My Heritage and will do the Ancestry DNA as soon as we can afford it.

You’re unique. We can help unravel your past through your DNA. DDC offers a range of exciting ancestry  testing services. Whether you’re looking to discover the origins of the maternal or paternal side of your family or you wish to determine your genetic profile and learn how much ancestral DNA you have from European, African, indigenous American or Asian peoples, we have the right test for you.
I recommend one of two options. It may cost a little more, but I would highly recommend saving the extra and using DNA Tribes® rather than spending over half the cost for minimal tribal/biogeographical pinpointed information. The primary benefit of STR rather than SNP testing is the availability of rich reference data. DNA Tribes® tests industry standard autosomal STR systems, which allow the identification of a person’s DNA profile not shared with any other person. Because these STR markers have been tested and used in the court systems around the world, they allow DNA Tribes® to perform the most thorough comparison of a person’s own DNA profile to over 1,200 ethnic groups (populations) around the world. At present, SNP testing from these other autosomnal DNA testing kits does not yet match the geographical detail of DNA Tribes® autosomal STR analysis.

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.
