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

5 Things You Can Learn From DNA Testing

Family History

Frustrated by limited access to only recent documents? Many ancestry tests allow you to trace your family history back much farther than traditional genealogy records. A select few even give you deeper detail about your family history.


Feeling a sense of emptiness? You can also use your DNA to 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

Lacking direction to find yourself? 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

Worried about the genetic legacies left you by your ancestors? 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 gain insights into a new wellness routine, and even learn about what traits you inherited from your parents.


Often sense you're alone and separated from the world? The communities you can build with some ancestry testing are incredible. You may discover relatives you didn't know you had, or countries you didn't know your family may have originated from, even royal dynasties you're descended from. The possibilities are endless.

How Do You Know Which DNA Test is Right for You?

With so many people clamoring to get their hands on the benefits listed above, more and more DNA testing companies have been rising to meet them.

Each DNA test has different strengths and weaknesses, and according to Kantar Media, the advertising spend by two of the biggest players in the market - Ancestry and 23andMe - now amounts to hundreds of millions of dollars a year to make sure you've heard of them.1

That's why we've compiled 3 of the most popular DNA tests, along with user reviews and criteria.

First, let's get started on the 3 Essential Tips You Must Know Before Buying a DNA Test…

3 Essential Tips You Must Know Before Buying a DNA Test

Tip #1: Buy from a Company That Cares.

Your data is always protected

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 aren't backed by leading geneticists. Instead, some of the biggest ancestry companies are owned in part by pharmaceutical giants or data companies.The best genetics companies are 100% privately owned, meaning they don't answer to corporate investors. Instead, they answer to you, the customer. Look for a company renowned for their customer service and professional pedigree.

Tip #2: Find a Test That Reveals When and Where Your Ancestors Appeared.

View your ancestors' migrations

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 also 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: Follow the Science and the Genetic Experts.

Dr. Alexei and Dr. Larisa Fedorov

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. Fortunately, the best DNA companies' science teams are headed by genetic experts, who have literally decades of experience in the genetics field.

Experts 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 professional scientists.
