10 Best DNA Test Kits in 2021 (100% Safe & Accurate)

10 Best DNA Test Kits in 2021 (100% Safe & Accurate)

There are hundreds of DNA tests out there. And all claim to be the highest quality, most private, accurate, and informative.

But our research and testing show that most DNA tests are lacking in these areas.

Our group of researchers trialed hundreds of the best at-home DNA tests for ancestry, diet and fitness, health and wellness, and pets – and rated each on its accuracy, functionality, and overall value. After spending months compiling and fact-checking the data, we’re finally able to bring to you this list of the top ten at-home DNA tests.

Overall, we were very surprised. Many of the well-known DNA testing companies were making bold claims that couldn’t be met. And many of the smaller brands were offering substantially better products at substantially better prices than the big brands.

How We Tested the DNA Kits

To see which companies provide the best service and most accurate information, we engaged with each DNA testing company as customers ourselves. We didn’t receive “free tests” in exchange for positive reviews. We took the tests instead.

Here’s exactly what we looked for in every single test:

  • Easy-to-use kits with fast shipping, clear instructions, and simple collection methods
  • Accurate results that you can rely on from accredited labs
  • Sufficiently quick turnaround to your results so you’re not left waiting too long
  • Highly detailed reports with useful insights and all the information you need
  • High-quality customer support channels

When Did DNA Testing Start?

Home-based DNA testing started in the late 1990s when a company known as GeneTree (later acquired by AncestryDNA with one of the best ancestry tests available) started to offer genealogical ancestry tests to the general public. These tests were pretty basic, and didn’t go beyond single generations, but it opened up a new field that was rich with opportunities.

The first dedicated direct-to-consumer ancestry testing company was FamilyTreeDNA, when in 2000, it partnered with the University of Arizona to offer Y-DNA and mtDNA tests to help people identify paternal lineages. Again, the tests at the time were nowhere near as detailed or accurate as they are now, testing for only a fraction of genetic markers. But at the time, being able to trace paternal and maternal genetic lineages across generations was revolutionary.

A few years later, in 2007, 23andMe further revolutionized the DNA industry by offering easy-to-access, at-home, saliva-based, ancestry tests. A particularly important distinction was that 23andMe used autosomal testing, which is now the standard test used across the entire genealogical DNA testing industry.

All three of these companies (AncestryDNA, FamilyTreeDNA, and 23andMe) are still going strong, offering widely available and highly accurate ancestry DNA tests to people around the world.

Since the initial success of these companies, and with the increasing technology of genome mapping, home-based DNA testing has become a major industry. There are now DNA tests for all different kinds of things – food allergies, emotional health, genetic disease risks, and even DNA testing for pets.

What Will You Discover from Your DNA Test?

DNA tests can tell you many things based on a fundamental aspect of your human existence – your genetic code. By decoding your DNA, you can understand how your genetic markers influence your life in many ways.

The three main things you’ll discover from your DNA test are:

  • All the ethnicities in your genetic makeup
  • What physical and emotional traits your DNA has given you
  • How your DNA influences your health, lifestyle factors, and behaviors

Your DNA test will tell you a lot of things about yourself, your ancestry, and your body’s unique biology. From which foods to eat (or not), and which exercise routine you should follow, to ethnicity estimates and tracking down long-lost ancestors, there are hundreds (if not thousands) of things you can learn from your DNA test results.

How to Choose the Best DNA Test for You

With so many DNA tests out there, it can be overwhelming to find the one that’s right for you. Here’s our roundup of the best DNA tests in each category to help you decide.

1. Ancestry

Many ancestry DNA tests like MyHeritage perform an autosomal test, meaning they look for genetic patterns across your chromosomes. This is great for everyone, regardless of biological sex, to identify overall ethnic percentages and even uncover some fun things about your DNA – like how 23andMe tests for what percentage Neanderthal you are.

Some ancestry tests also analyze Y-DNA and mtDNA; if you’re interested, Living DNA is a great option. These look for patterns in your Y and X chromosomes, which help trace your paternal and maternal lineage. With these tests, you can see where in the world your family comes from and even discover migration maps.

If you’re studying your heritage because you want to find DNA matches and perform genealogical research, you should look for an ancestry testing service like MyHeritage or AncestryDNA that allow you to contact genetic matches and build a family tree.

2. Family Tree Builders

MyHeritage and AncestryDNA have the two best family tree builders available.

Each performs genetic testing, allows you to contact genetic matches, has an extensive database of historical documents needed for advanced genealogical research, and allows you to easily build and share a family tree. They even send you hints and tips to help you find matches and records.

3. Health and Wellness

Health and wellness tests explore how your DNA impacts your predisposition for certain diseases, as well as whether you might carry the genes for specific health conditions.

Companies like Everlywell and LetsGetChecked use finger-prick blood tests instead of saliva samples to more closely look at a person’s current health, testing for things like hormonal balance, food allergies, and vitamin levels.

4. Diet and Fitness

Diet and fitness DNA tests see how your body processes the nutrients it receives from food and exercise. A DNA test like Living DNA tells you which foods you should be eating for optimal nutrition, based on your body’s specific needs.

It actually gives you a list of over 100 foods. You can also learn which foods to avoid, whether you might have any intolerances, and, depending on which test you choose, get personalized meal plans.

DNA tests like Living DNA give you personalized workout recommendations so you can maximize your body’s performance based on your genetic type. It tells you which exercises to do and when, for how long, and even how your body builds muscle and recovers from exercise.

5. STD Tests

You can test for a number of STDs like HIV, syphilis, and chlamydia with at-home testing kits. Instead of going through the trouble and awkwardness of making a doctor’s appointment, you can screen your sexual health at home.

Both Everlywell and LetsGetChecked are great choices, with a huge list of individual STD tests and bundle kits. They’re both delivered in discreet packaging to your door, with a simple swab, urine, or finger-prick blood sample. And they can give you your results in a matter of days.

6. Pet DNA

Your pets also have unique DNA that can be used to determine their breed type, the likelihood of shedding, coat length, and patterning.

Apart from satisfying your curiosity, knowing the ethnic heritage of your four-legged friend can help you to increase their overall health by giving them the right kind of food, activity, and medical treatment that their breed requires.

DNA tests like Embark and Wisdom Panel can tell you which breeds are in your dog’s genetic makeup over four generations, their breed characteristics and personality type, and even their risk of health conditions.

Are There Any Risks Associated with DNA Tests?

In general, no. There are no physical risks associated with taking a DNA test. That said, for precautionary measures, you should consult with your doctor before taking a DNA test while pregnant.

However, there are some dangers of DNA testing. For example, if you send off your unique genetic code to a fake DNA testing company, it is possible that it could steal your DNA information, your payment information, and maybe even your overall identity.

We’ve tested over 100 DNA kits and all the companies on this list are 100% safe and legitimate.

Please remember that consumer-based health and wellness DNA testing is not a substitute for medical advice. You still need to consult with a medical professional before starting or changing any kind of medical regimen.

DNA Testing and Privacy Issues

All reputable DNA testing companies have a privacy policy in place that explains how your DNA can and can’t be used.

In general, when you hand over your DNA to a testing company, you give permission for it to use your DNA sample to further its research and testing capabilities. Your DNA is always anonymized before any kind of research or analysis takes place.

That said, some DNA testing companies also have policies in place that allow law enforcement to access your DNA sample if they have a legitimate and legal reason to do so.

In 2018, police were able to catch a wanted serial killer through DNA samples his distant family members had submitted through the open-source genealogy website GEDmatch. Some people view this kind of thing as an invasion of privacy, and this has sparked a large debate over whether or not consumer DNA testing is actually secure. And there is still no legal consensus on whether or not DNA taken from a DNA test company can legally be used in court to identify a suspect.

That said, almost 100% of the time, your DNA is safe, private, and anonymous. It only has the potential to be used against you if you buy through an untrustworthy company or if you do something illegal.

How to Order and Take a DNA Test

The first step is identifying which DNA test you need to take. After you’ve compared the best DNA tests and found the one you want, you need to do the following:

  • Place an order through the website
  • Provide a physical address where the testing kit can be mailed
  • Perform the test as instructed on the packaging of the testing kit
  • Return the testing kit to the testing company (some companies include a pre-paid envelope while others require you to get your own postage)
  • Wait for your test to be processed (usually, around 2-4 weeks, though some tests have a waiting period of up to 8 weeks)
  • Receive and review your results, either via mail or an online system

Which At-Home DNA Tests Is the Best Value for Money?

Some companies might give out a lot of information for a cheap price, but if that information is not useful to you or is not accurate, it’s irrelevant how much the test costs.

FAQs

How does DNA testing work?

DNA testing works in a number of ways depending on which type of DNA test you’re taking.

In its simplest form, DNA testing works like this:

  • If you’re taking an ancestry test, the laboratory compares your DNA sample against another DNA sample that is known to have certain qualities (like belonging to a certain ethnicity).
  • If you’re taking a health and wellness test, the laboratory looks for certain genetic signatures that are medically known to produce a certain kind of effect (like predisposing you to a certain disease).

How accurate is DNA testing?

Most genetic testing companies advertise a 99% accuracy rate. Depending on the type of test you take, this could be even as high as 99.9%. Remember, it’s impossible to get a test that’s 100% accurate.

How much does a DNA test cost?

The cost of a DNA test is dependent on a lot of different things, like what type of test it is, what information you’re getting, and whether or not the company is reputable.

In general, for a basic ancestry DNA test, you shouldn’t spend more than a couple of hundred dollars. Some companies bundle ancestry testing with health and wellness testing, and this can raise the price substantially.

Overall, for a detailed ancestry test coupled with a pretty detailed health and wellness test, you won’t need to pay more than $300.

We’re always searching for the latest and best deals to help you save money. Check out our coupons page to grab a great offer.

Which DNA test has the largest database?

Right now, AncestryDNA has the largest ancestry DNA database in the world with over 18 million samples. It also has over 20 billion historical records.

What is an ethnicity estimate?

Your DNA contains unique genetic markers that, when compared with other DNA samples, can be used to identify common patterns in ethnic heritage.

The ethnicity estimates you receive from a DNA test are based on similarities with other DNA tests from a known geographic and ethnic lineage. This provides a controlled and correlated estimate of which part of the world and which ethnic group your DNA originated from.

Can I take my DNA health test results to a doctor?

Absolutely! Not only can you, but you should also take your DNA results to a doctor.

You and your doctor can review the DNA test results and come up with a proper treatment for you based on your specific genetic makeup. Any information you can provide about your body’s biological makeup will be extremely useful for a doctor when treating you, especially when it comes to your risk of health conditions.

How long does an ancestry DNA test take?

There are many different DNA tests available for ancestry, and their turnaround times vary widely. For instance, 23andMe is one of the fastest, typically giving you your results in 2-4 weeks. You can expect to wait as long as 8 weeks for some other ancestry tests, though.

What do my DNA ancestry results mean?

After you take an ancestry DNA test and send in your sample, the testing company analyzes and interprets your DNA, then sends you a report – either posted on its website, via a mobile app, or through a PDF or even a printed book.

At a minimum, an ancestry DNA test estimates what percentage of your ancestry comes from various ethnicities and where in the world those ancestors probably originated. It tells you that you’re 38% one ethnicity and 15% another ethnicity, for example.

Most ancestry tests go a little further by also giving you a list of your genetic matches, based on people’s DNA they hold in their database. Essentially, these people are your relatives, such as your 3rd cousin, great uncle, 2nd aunt, or something else.

More comprehensive ancestry reports can cover additional things – like what maternal and paternal haplogroups you’re descended from, going back hundreds of thousands of years. You can get this level of information from a test like MyHeritage, as well as much more.

What do ancestry DNA test results look like?

Ancestry tests always deliver some sort of report that summarizes and explains findings. Usually, this is a PDF report through an online dashboard, but it might be a combination. For example, you can get interactive maps to trace heritage and haplogroup lineage with a service like AncestryDNA. Some even have mobile apps.

Your report usually includes a breakdown of all the ethnicities in your DNA with percentages. These are typically reflected on a heat map so you can visualize your heritage around the world and learn more about each location.

Most ancestry DNA test reports also show you which biomarkers were tested and the exact genetic variant you carry.
