3 Essential Tips You Must Know Before Buying a DNA Test

Your Free Guide to the Highest Rated DNA Test

Looking for a good Ancestry test?

Dear Reader,

Who are your ancestors?

They’ve left you clues to their identity deep within every cell of your body.

Through vast migrations, fires, floods, droughts, and plagues, they held on and survived. You exist at this very moment in time because of them.

Yet you’ve never had a chance to get to know your ancestors.

Until now.

So, who are your ancestors? How can you decipher the code they left behind, which reveals their amazing story?

One solution is DNA testing. Its popularity has exploded in recent years, with the total number of people tested by consumer genetics companies projected to double in 2021, according to an MIT study. This DNA boom has made genetic testing one of the hottest conversation starters at dinner tables and water coolers across the world.

The DNA market doubled in 2020—for the fourth year in a row.

It’s no surprise that DNA tests are in high demand. The things you learn from them are irresistible:

Family History—Many ancestry tests allow you to trace your family back much farther than traditional genealogy records. A select few even give you deeper detail about your family.

Ancestry—You can also use your DNA figure out where you and your family came from. With more advanced tests, you can even find out WHEN your family arrived in certain locations.

Personal Identity—On top of these first two benefits, digging into your family history and ancestry enables you to find out more about who you are personally.

Health Info—While the main draw is ancestry, you can also use DNA testing to uncover important health information. The best DNA tests will enable you to lose weight, optimize your vitamin routine, and even learn about what traits you inherited from your parents.

Community—Finally, the communities you can build with ancestry testing are incredible. You may discover relatives you didn’t know you had, countries you didn’t know you were a part of, even royal dynasties you’re descended from. The possibilities are endless.

With so many people clamoring to get their hands on the benefits listed above, more and more DNA test companies have been rising to meet them. Unfortunately, they’re not all created equal.

Now it’s harder than ever to find a good DNA test…

Luckily, you’re in the right place. Our team of scientists, researchers, and writers at Genetics Digest know the field better than most. We’ve examined nearly every DNA test in the booming market. We’ll help you sort out the great ones from the “cheap knockoffs.”

With that said, let’s get started on the 3 Essential Tips You Must Know Before Buying a DNA Test

Tip #1: Don’t buy a brand by how “popular” it appears to be.

Some brands have a great marketing team with a massive advertising budget. You might see/hear their ads everywhere. That’s because they’re spending millions to make sure you’ve heard of them.

Despite the great marketing, some of those companies have subpar services at best. They’re more worried about making a sale than they are with actually delivering a quality product. In short, these companies focus on business rather than science, and frequently aren’t backed by leading geneticists.

To make matters worse, some of the biggest ancestry companies are owned in part by pharmaceutical giants or data companies—meaning your personal DNA information may be handed over to corporations to turn a profit.

The best genetics companies have top-notch data security, and are 100% privately owned, meaning they don’t answer to investors. Instead, they answer to you, the customer. Look for a company renowned for their data security and professional pedigree.

Tip #2: Don't Miss Out on Deeper Detail

One of the most common complaints we see from ancestry customers is that their results “fall flat”—you get a basic pie chart breakdown of where your ancestors are from, but a disappointing amount of information about how or why you got those results. And we all know that ancestry is more than just a bunch of boring percentages.

The best DNA tests feature an Ancestry Timeline that tells you not only where your ancestors are from, but exactly how and when they got there, enabling you to form a clearer, fuller picture of your family history. These top-quality tests give you the best of both worlds of broad genetic results and deeper ancestry detail.

Tip #3: Don't Forget to Ask the Experts

On a similar note to our #1 tip, you don’t want to go for the loudest, flashiest DNA brand—instead, look for true experts in the field of genetics. After all, you want highly qualified scientists and researchers handling your DNA, not a bunch of college kids at a startup. Fortunately, the best DNA companies are headed by genetic experts, who have literally decades of experience in the genetics field.

Experts are not only more knowledgeable about your DNA—they also tend to be far more responsible than companies who are just looking to make a quick buck. These genetic investigators have dedicated their lives to helping you find out the meaning behind your DNA and family history, and they won’t rest until their customers’ curiosity is satisfied. If you want your burning questions about your DNA and family history answered, make sure you find a company with a professional scientist in charge.

Overview: 23andMe boasts one of the most detailed and accurate Ancestry Reports of all DNA testing companies. They’re #2 by a slim margin, as they have slightly fewer Ancestry & Trait reports than our #1 choice. They also have an ancestry timeline, but it features far less depth and detail than our top choice, only going back 8 generations at most.

Company Reputation: 23andMe was founded in 2006 by Anne Wojcicki, Linda Avey, and Paul Cusenza. Their goal is to “help people access, understand, and benefit from the human genome.” To date, they have published more than 100 peer-reviewed studies in scientific journals.

One of 23&Me’s top investors is GlaxoSmithKline, a pharmaceutical company that has been implicated in numerous scandals, including false claims suits. As a result, 23&Me’s customers are almost guaranteed to have their data used for pharmaceutical research.

Details/Accuracy of Reports: Today, 23andMe is one of the top players in the DNA testing market. Their Ancestry reports come with above average detail and accuracy, only slightly lagging behind our #1 choice. View Full Report

#3 AncestryDNA


  • Autosomal DNA Test Offered

Overview: Ancestry.com has been in business for a long time, which has allowed them to learn from mistakes and slowly acquire a large base of customers from their genealogy services. This has made them one of the top players in DNA Testing.

Company Reputation: Ancestry Publishing was founded in 1983 and eventually grew into a genealogy service, allowing customers to sort through historical records to fill out family trees. They added DNA testing to their list of services in 2007, but didn’t do it themselves until 2012.

Ancestry.com has an “informed consent research” clause in their service. You can opt out, but it’s easy to miss, and plenty of customers have realized too late that their data is being used in genetic research. Ancestry is also owned in part by AOL and Compaq, both large data companies. Finally, GIC, the Government of Singapore Investment Corporation, is also a major investor, meaning Ancestry customers’ DNA data belongs in part to a foreign government.

Details/Accuracy of Reports: Ancestry DNA’s reports have 30 regions, mostly in Europe. Many customers will find this satisfactory, but our #1 and #2 choices give far more detail. Ancestry DNA’s greatest strengths lie in the size of their customer base and in their genealogy service that allows you to search through historical records to fill out your Family Tree.
