This analysis will involve studying DNA in the sample cells to look for mutations that indicate a person’s risk of developing specific health conditions. Nebula Genomics Deep sequences 100% of your DNA, providing a large amount of data regarding your health, traits, and ancestry. Additionally, its subscription model allows you to access new reports that are regularly rolled out, and the company provides a number of privacy options to protect your genetic data that others do not. The best at-home DNA test kits provide a broad spectrum of information about your health, traits, and lineage—along with social options that allow you to connect with your relatives.
At less than $100, however, the basic MyHeritage DNA Test is a great low-cost option if you want to learn more about your lineage. For a less expensive option that doesn’t offer full genome sequencing, you can choose the Basic Genome Sequencing plan for $299. Or for optimal accuracy, select Ultra Deep Whole Genome Sequencing for $2,999.

FamilyTreeDNA also doesn’t have nearly as many members as AncestryDNA or 23andMe. (They have 1.5 million versus the others’ 18 and 12 million, respectively.) But you can use the service to build a family tree. You can also join projects to further share and compare your DNA with similar people, like the Aberdeen & North East Scotland Project. When you click on a region, FamilyTreeDNA provides a few paragraphs of information about the history of the area, but that’s it. For the DNA geeks out there, the company throws in jargon like SNPs and centiMorgans .
Established in 1995, DDC was founded on the belief that technological advancements in DNA testing should translate to services that are accessible and affordable to everyone. DDC's laboratory in Fairfield, Ohio is nationally and internationally recognized through multiple accreditations. At-home DNA testing is a convenient and quick way for a person to get insights into their genetics. A person can buy an at-home DNA test to find out more about their family history or see if they carry traits that could make them more likely to develop certain health conditions. Other factors can also influence disease risks, such as lifestyle, medical history, and environmental factors.

Verywell Health content is rigorously reviewed by a team of qualified and experienced fact checkers. Fact checkers review articles for factual accuracy, relevance, and timeliness. We rely on the most current and reputable sources, which are cited in the text and listed at the bottom of each article. Content is fact checked after it has been edited and before publication. Importantly, at-home DNA test results cannot impact your health insurance or employment prospects. No matter what you find out from your DNA, the Genetic Information Nondiscrimination Act of 2008 forbids discrimination based on your genes.
We didn't test those for this roundup, as many solely looks for users' genetic connections to one continent , and therefore may only paint a partial—if significant—picture of someone's heritage. However, since each testing company divides its regions differently, these specific areas will be different. For example, AncestryDNA lists “Germanic Europe” as a region, whereas 23andMe uses “French & German” to describe a similar area. While DNA test kits use your genetic code to show you where your ancestors theoretically came from, you might wonder how they work. But across the board, my results were pretty much the same at the continental level, sparing a few percentage points here and there.

The Invitae Genetic Health Screen investigates up to 147 genes to assess your potential genetic risk for cancer, heart disease, and certain inherited conditions. It also offers genetic counseling with an expert once you receive your results. The 23andMe+ Membership costs $228 total for the 23andMe Health + Ancestry Service as well as a one-year membership to premium features.
The ancestry of European descendants can be determined with greater detail than people from other continents . The reason lies in the size of the reference database—i.e., DNA data from Europeans have been collected more widely and for longer. What’s more, many of the initial customers of these DNA testing kit companies were of European origin, further increasing that reference data. However, with such personal data—your literal DNA—being sent to these companies, there come privacy concerns and the fear that this information could be misused or sold.
Having a genetic mutation for a certain disease does not mean someone will develop the condition. A 2019 national survey concluded that genetic specialists were the best group of health professionals to advise a person on the results of genetic tests. Not every DNA test offers access to genetics professionals, so a person may need to seek genetic counseling themselves to learn more about their test results. To provide clear and reliable information about your ancestry, DNA testing companies rely on databases of genetic information. These databases usually include publicly available genetic information as well as genetic data from a company’s other users. DNA matches aren’t as vast on MyHeritage because its 4.8 million people database is much smaller.
So they can trace back your ancestry only on your mother’s side of the family. MtDNA tests can provide information going back 8-10 generations, but they don’t offer much information about family structure. However, at-home tests become less accurate if you want information about what specific country your ancestors are from. For example, if you want to know just how much Italian heritage you have, you might find that an at-home test doesn’t provide the level of detail you’re after.
This doesn’t have anything to do with the quality of the test kit or the sequencing process. Rather, it’s because different DNA testing services sequence different genes. That’s part of the reason why it makes a lot of sense to stick with popular ancestry testing companies like MyHeritage and LivingDNA. These companies have already had millions of users test their ancestry and contribute genetic information. This means you get access to more detailed information about your own ancestry.
AncestryDNA also offers an “ethnicity inheritance” feature that shows a side-by-side view of where you likely inherited your background. While 23andM3 offers this for people with an X and a Y chromosome, by tracing the DNA from each. But AncestryDNA does it for people regardless of their chromosomal makeup.
One of the most common reasons to use an at-home DNA test is to learn more about your ancestry. DNA tests are great for this, especially if you want to know about your ethnicity at the continental level. They can readily tell you whether your ancestors came from Europe, the Middle East, or Asia, for example. Molly K.

You then receive an email notifying you that your results are ready to explore on the AncestryDNA website. We use industry standard security practices to store your DNA sample, your DNA test results, and other personal data you provide to us. In addition, we store your DNA test results and DNA sample without your name or other common identifying information. At any time, you can choose to download your DNA Data, have us delete your DNA test results as described in the Ancestry® Privacy Statement, or have us destroy your physical DNA saliva sample.
