The trick for collecting a saliva sample is to give yourself plenty of time to create enough spit to fill your tube to the fill line (not including any bubbles). You should not eat or drink anything for at least an hour before collecting your sample, so it’s best to plan to collect your sample before eating. Our testers collected samples before lunch and found that thinking about the upcoming meal made saliva production easier, particularly as we collected multiple samples. Planning ahead and making sure you stay hydrated before you collect a saliva sample helps as well.
The companies providing ancestry DNA tests are making most of their money from selling the genetic information as opposed to running the tests. Companies purchase this information to increase the size of their genetic databases. Nearly half the companies selling ancestry information are selling to more than just one company. These are sometimes pharmaceutical companies attempting to understand how specific human genome sections can help develop new drugs. Certain mutations will impact the effectiveness of these drugs. The original DNA sample is only destroyed by roughly ten percent of these companies. Most companies keep or sell the sample. This means it is both your data and saliva being sold.
When I took my first DNA test in 2016 I was disappointed, in part because I didn’t do my research, so my goal in this review is help others avoid that scenario. Beyond ancestry tests, there are companies that recommend wines or exercise regimens based on your DNA. With all the available options, it’s easy to default to a recognizable name, which isn’t necessarily bad. But certain tests do specific things better. Our goal is to match your expectations with the test that fits best.
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.
I sadly have to agree as after the results appeared in my Ancestry account I was very disappointed to see that they failed to disclose any sign of my Italian heritage at all and even clicking through the Engilsh ethnic breakdown showed absolutely NO connection to any place whatsoever so apparently I am an alien who was dropped here from outer space so I could not recommend this as a service that produces a valid ethnic breakdown at all. Their results graph and click through breakdown are extremely limited, especially after comparing them with other services so from the ethnicity perspective, think they are bordering on false advertising!!
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.
McCartney says that anxious people often contact her, saying they wished they hadn’t done the tests. “These companies often say that it’s worth it for the helpful advice. But I can give you really good advice right now without seeing a single test result: be active, have lots of social networks, do work you enjoy, try not to smoke or drink too much, don’t be overweight or underweight, eat lots of fresh fruit and vegetables. Nobody needs to get tests done to get that kind of basic lifestyle advice.”

I was born in NYC, the youngest of five kids. My parents and three older siblings were born in Bogota, Colombia. My name implies Hispanico/Latino roots but when I’m with my Polynesian friends people always think I’m Hawaiian or a mix of Polynesian and something else. I recently attended a Nepali church service and people asked me what part of Nepal I was from.
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.
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.
There are many places you can upload your raw DNA, and several of them are free. Popular third-party DNA analysis tools include GEDmatch and Promethese. GEDmatch is a free, open database and genealogy site that gives additional DNA relative matching and trait results. This tool has information from users of multiple different testing companies. Promethease compares your raw DNA information against scientific reports that link certain markers to health conditions, though you should take these results with a grain of salt as genetic links do not equal a diagnosis.
Some concerns about the ultimate efficacy of certain home tests seem to emanate from the industry itself. I did a telomere-measuring test (a mouth swab) by Titanovo, based in north Colorado, which came back saying that my telomeres were too short, putting me at 10 biological years older than I am. However, when I contacted Titanovo, it explained that it had stopped telomere measuring and was now concentrating exclusively on its DNA-utilising “bioinformatics” health, fitness and wellbeing website (analysing client data from other genetic testing sites).
Most ancestry DNA kits cost about $100. AncestryDNA, 23andMe’s Ancestry test and National Geographic’s Geno 2.0 test all fall nicely into that price point. If you’re looking for a bargain, we recommend waiting to buy until your preferred test is on sale, as they’re often available well below their usual price. To get the most for your money, buy an Ancestry or 23andMe kit on sale then upload your raw data to MyHeritage DNA’s database, which is free.
We evaluated each kit by ordering one, just like any customer would, and tracking how long it took to arrive at the lab and to get processed. Then we compared the breadth and depth of the results to see what rose to the top. The whole process was a lot of fun, in part because of the anticipation of getting the results. Most of the kits warn that testing your DNA can lead to surprising—even life-changing—results. For example, there's the story of a woman who thought she was Irish, but her DNA test revealed she was also European Jewish, Middle Eastern and Eastern European. After diligent research, she discovered that her father, who had died years earlier, had been switched at birth with another child.
Pet DNA tests: Companies like Embark, Wisdom Panel and many others offer genetic health risk screenings, trait analyses and breed percentage information for dogs. These canine ancestry tests allow you to confidently state that your mutt is part Irish wolf hound and give you key information about your pet’s heritage for insights into potential health issues. For example, if you find out one of your rescue dog’s parents was likely a purebred boxer, you could speak with your vet about breed-specific needs. Basepaws DNA CatKit promises information about your cat’s breed and traits with just a hair sample, though it offers swab kits for hairless cats. The kit also tells you how closely related your kitty is to wild cats like lions, tigers and (bears, oh my!) ocelots.]
In McCartney’s view, enough testing is already done in this country (sometimes too much) and there are issues of regulation and “informed consent”. “People are given very dramatic reasons to have these tests – it could help save your life, it could help improve the quality of your life – but where is the actual controlled evidence that these tests have ever done that? There’s no evidence that says doing these tests makes people become healthier.”
