The Best DNA Tests for Discovering Your Ancestry

Human DNA– short for deoxyribonucleic acid– is the molecule that makes you unique. In other words, it’s what tells your cells how to work and what kinds of proteins to make. Though all humans have the same type of DNA, nobody’s DNA is exactly identical to anyone else’s. In 2008, researchers from the University of Alabama at Birmingham discovered that even identical twins have DNA differences. These DNA differences can reveal a lot about what makes us who we are. Various genes control not only our eye and hair color, but also how well we can carry a tune. Many of our emotional responses are influenced by our genes, as well.

For years, only law enforcement agencies, research groups and other similar organizations could afford to pay for DNA testing because technical limitations kept the price of DNA sequencing high. At one time, it cost over $100 million to sequence a single genome. According to the National Human Genome Research Institute, that cost has fallen all the way down to just $1000 in recent years.

The dramatic drop in costs associated with DNA processing has given rise to a booming industry of consumer DNA testing services. Today’s DNA tests can do more than help you flesh out your family tree. Some can identify specific traits, potential medical risks and more.

Here are the best DNA tests you can buy:

  • FamilyTreeDNA’s Family Finder test compares your DNA to the two million people that have submitted DNA samples to the company. Founded in 2000, FamilyTreeDNA was the first mover in the consumer DNA testing industry.
  • If you opt to go with tellmeGen’s DNA Test Kit, you’ll find out important information about your health and get information about your ancestors. When new discoveries enable scientists to get more information out of your sample, you’ll get new information for free.
  • MyHeritage’s DNA Test Kit is somewhat pricey, but it has the best social network for connecting with newly discovered DNA relatives.
  • Like the brand name suggests, AncestryDNA’s Genetic Ancestry test caters to people that want to learn more about their ethnicity and ancient origins. It’s one of the most specific DNA tests for determining ancestry on the market.
  • If you’re looking for a DNA test that does it all, you may want to try 23andMe’s Health + Ancestry test. It reveals crucial health risks, connects you with your DNA relatives and sheds light on your ancient ancestors.

The most established DNA test service

FamilyTreeDNA – Family Finder DNA Test

FamilyTreeDNA made headlines when it came out back in 2000 because it was the very first consumer-oriented DNA test to hit the market. Today, FamilyTreeDNA’s database– which is stored on-site in the company’s own storage facility– contains samples from over two million people. One of the Family Finder test’s most interesting features is ancientOrigins, which matches your DNA to specific archeological dig sites in Europe.

In a nutshell

Buying guide for DNA tests

Key considerations

Number of regions and countries

Some DNA tests that have an ancestry feature can only trace your genes back to general regions of the world, but others are more precise. Scientists have obtained human DNA from various dig sites around the world and some DNA tests can trace your lineage back to these exact locations.

Processing time

Most DNA test manufacturers deliver your results in around four weeks’ time. The fastest DNA testing services have a two-week turnaround. On the other end of the spectrum, other DNA testing services make their users wait eight weeks or more. The amount of time you’ll have to wait may vary depending on how busy the company is.

Sample type

There are two main types of DNA test samples: saliva samples and cheek swab samples. Both types of tests are easy to perform and accurate. However, if the thought of collecting saliva from your mouth leaves you feeling squeamish, you may want to go with a cheek swab test instead.

Subscription plans

Be sure to find out whether or not you’ll have to pay a monthly subscription to get the most out of your DNA test before you buy. Most DNA testing services give you full access to all their features after you buy a test, but some lock the best features behind paywalls.

Health risk identification features

Some people are more prone to developing diseases like diabetes and Altzheimer’s than others. You can learn more about these types of risks by purchasing a DNA test that has a health risk identification feature.

Social network features

Many DNA testing services provide a built-in social network that lets you identify and connect with your DNA relatives. If these types of social features interest you, you may want to go with a DNA testing service that has a large number of active users.

Traits analysis

If you’re curious about what kinds of natural gifts and behaviors you may be likely to have, you may want to consider purchasing a DNA test that can identify traits. Many of the traits that make us who we are can be found in our DNA. For example, some people are born with the natural ability to identify and match musical tones.

Mobile apps

A growing number of DNA testing services offer mobile apps. These apps let you do things like build your family tree, interact with DNA relatives and get detailed information about your test results on the go.

Information privacy policy

It’s a good idea to read your prospective DNA testing service’s terms of service before you join. DNA testing services that put privacy first give their users complete control over their information. These companies will let you opt out of any information sharing programs that your DNA testing company may be participating in.


Scientists learn new information about human DNA all the time. But when new data comes out, will your DNA testing service update your results for free? Some do provide free updates, but others don’t.

Price ranges


Low-cost DNA tests will tell you where your genes originated and reveal your ethnic makeup. Such tests typically cost around $75.


Most DNA tests that you’ll find while shopping cost around $100. At this price range, you’ll find that many DNA tests cater to a specific use case, like genealogy or health risk screening.


The most expensive DNA tests give you access to huge DNA databases and large social networks. These premium DNA tests can usually do more than one thing, as well. If you intend to buy a DNA test that can do ancestry tracking, trait recognition and medical risk identification, expect to pay $150 or more.

Frequently asked questions

Q: I’m interested in learning more about DNA ancestry testing. Which books should I read?
A: The Family Tree Guide to DNA Testing and Genetic Genealogy not only covers the differences between mtDNA, Y-DNA, autosomal DNA and X-DNA tests, but also helps you understand and interpret your results. For a more personal story about a surprising DNA journey that upended a life, try Bill Grifith’s touching memoir, The Stranger in My Genes. Bonnie Rochman’s The Gene Machine provides an excellent introduction to the ethical and legal issues around DNA testing.

Q: Will I end up with different results if I take several DNA tests?
A: That could happen, since a DNA testing service is only as good as its DNA database. Incomplete data may produce inaccurate results. The companies that sell DNA tests don’t share their data and there is no industry standard for accuracy. That’s why it’s important to choose an established DNA testing service that’s run by experienced scientists.

Q: How do DNA testing services make money from the information they collect?
A: If you’re concerned about how your genetic information will be used, you’ll need to read all the fine print on your prospective DNA testing service’s website.Many DNA testing services sell their customers’ data to pharmaceutical drug manufacturers. However, some DNA testing services have pledged to never do this.


  • Get your relatives involved. The more data your family provides, the more fun you’ll have because you’ll get more potential leads when you try to look for DNA relatives online. Many people buy DNA tests for their loved ones as gifts.
  • Stick with the most popular brand names. Lesser-known DNA testing services often don’t do enough to protect their customers’ privacy and security.
  • If you like to travel, you may want to consider booking a genealogy tour after you get your DNA test results. A number of genealogy tourism services have sprung up in Ireland, Africa and elsewhere around the world.
