Many DNA databases, including Ancestry, 23andMe and MyHeritage DNA, have family search features, which match your DNA with that of potential relatives. These features help users searching for family, including adoptees and children conceived through sperm donations. Almost every DNA testing service we interviewed for this article had a story ready about how its service facilitated a heartwarming family reunion. Like these from Ancestry, this one from MyHeritage and this one from 23andMe. Because many DNA services also have resources like family tree builders, the tests work in tandem with genealogical research.
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.
The first kit I try is Thriva’s baseline test (£49), which, like all its products, checks your blood. The box arrives promptly enough (containing spring-loaded needles, a little collection tube, antiseptic wipes, plasters, etc), but there’s a problem. The idea is to prick your finger and massage blood into the tube, but I just end up making my fingers sore and what I get out barely smears the top of the phial. Maybe it’s just me, but it turns into a right faff. In the end, I take advantage of Thriva’s service to send someone out to take a sample of blood from my arm.
There are mixed reactions to the use of ancestry DNA databases in criminal cases. On one hand, the rise of readily-available DNA information for millions of people has led to the arrests of several suspects related to long-cold cases, including the arrest of the Golden State Killer. On the other hand, law enforcement accessing private databases of genetic information from consumers raises several questions regarding privacy and ethical issues.
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.
I would like to know about the paternal side of my father’s family. My problem is that there are no living males. (My father’s sister had a son that is still living, however, if he does a Y-dna test I believe that will only give out HIS father’s information). I wonder if I should have this male cousin take the mtDNA test instead. That way I could at least find out more about the maternal side of my father’s family. Any advice?
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.
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.

In addition to showing geographic ancestry percentages, some direct-to-consumer DNA tests also include insights about physical traits like hair and eye color. With 23andMe, this trait information is mostly available in the upgraded Ancestry + Health kit, but some interesting tidbits can be found in the Your DNA Family report, which is available if you opt to participate in the DNA Relatives service. This report tells you interesting information, such as that your DNA relatives are 32 percent more likely to own a cat or 11 percent less likely to have lived near a farm when they were young. DNA Passport by Humancode offers information about more than 20 physical traits, from appearance to grip strength. Ancestry DNA recently added its AncestryDNA Traits upgrade for $10, and it lets customers who have already taken one of its tests unlock information about 18 genetically influenced traits, including bitter taste perception, freckles and cilantro aversion.
DNA test companies that use genotyping technology, including 23andMe and Ancestry, allow you to download your raw DNA file. A raw DNA file is usually a text file that contains all the information about your genetic code gleaned from the company’s examination of your DNA. This is comprised of several hundred thousand markers known as SNPs (Single Nucleotide Polymorphisms). Most raw files are organized into five columns: the SNP coded into an rsID number, the chromosome the SNP is located on, the location of the SNP on the chromosome and the two alleles for each SNP.
Hello, my mother is British and was adopted by two other British people who I of course consider my Grandparents. Her birth mother is also British she doesn’t know her father but been told he is Irish. My father is American however he is African American. I myself was born in Britain Would you still suggest I should use living DNA or a different provider? The main thing I really want to know is the ethnicity part.
