With the rise in popularity of DNA testing kits, many people are turning to companies like MyHeritage to learn more about their ancestry and genetic makeup.

However, with so many options available, it can be difficult to know which company to trust. One of the most common questions people have is whether or not MyHeritage is accurate.

According to various reviews and studies, the accuracy of MyHeritage’s DNA testing results can vary.

Some users have reported discrepancies between their results and what they know about their family history, while others have found the results to be spot-on.

It’s worth noting that no DNA testing kit is 100% accurate, as the science behind it is still relatively new and constantly evolving.

So, is MyHeritage accurate? The answer is not a simple yes or no. While the company’s results may not be 100% accurate for everyone, they can still provide valuable insights into a person’s genetic makeup and ancestry.

It’s important to keep in mind that DNA testing is just one tool for learning about one’s family history, and should not be relied upon as the sole source of information.

Understanding MyHeritage’s Accuracy

When it comes to genealogy and DNA testing, accuracy is of utmost importance. In this section, we will explore MyHeritage’s accuracy in detail.

What Does MyHeritage Claim to Do?

MyHeritage claims to provide accurate ethnicity estimates and family matching. The ethnicity estimates are based on a comparison of the user’s DNA to reference populations from around the world.

Family matching is based on the user’s DNA and family trees uploaded to the site.

MyHeritage also claims to provide health reports that are based on scientific research conducted by their science team.

How Does MyHeritage Gather Information?

MyHeritage gathers information through DNA testing and family tree uploads.

Users can upload their raw DNA data from other testing companies to MyHeritage for free, or they can purchase a MyHeritage DNA kit.

The DNA data is then compared to reference populations from around the world to provide ethnicity estimates.

Family tree uploads allow MyHeritage to match users with potential relatives based on shared DNA and family tree information.

MyHeritage’s health reports are based on the user’s DNA, which is read in MyHeritage’s lab using Illumina’s Global Screening Array (GSA), customized by MyHeritage.

The health reports are based on robust scientific research conducted by the MyHeritage Science team and peer-reviewed academic papers.

It is important to note that MyHeritage’s accuracy is limited by the size and diversity of its reference population.

MyHeritage has a smaller DNA database compared to other testing companies, which could lead to less accurate ethnicity estimates for certain populations.

However, MyHeritage has a significant user base in Europe, making it more accurate for people with European ancestry.

Factors That Affect MyHeritage’s Accuracy

Data Quality

The accuracy of MyHeritage’s results largely depends on the quality of the data provided by the user.

If the user’s family tree is incomplete or inaccurate, it will affect the accuracy of the DNA results.

Additionally, if the user’s DNA sample is contaminated or not handled properly, it can also affect the accuracy of the results.

Sample Size

The size of MyHeritage’s DNA database is smaller than some of its competitors, such as Ancestry.

This means that the accuracy of the results may be affected by the smaller sample size.

Geographic Location

The accuracy of MyHeritage’s results can also be affected by the geographic location of the user’s ancestors.

MyHeritage has more regions around the world compared to some of its competitors, which can help narrow down ancestry for people with diverse backgrounds.

However, the accuracy of the results may be lower for people with ancestry from regions that are less well-represented in MyHeritage’s database.

Historical Records Availability

MyHeritage’s accuracy can also be affected by the availability of historical records.

The accuracy of the results can be improved when there are more historical records available to cross-reference with the user’s DNA results.

MyHeritage has a large collection of historical records, which can help improve the accuracy of the results.

MyHeritage’s Accuracy Compared to Other DNA Testing Companies

When it comes to DNA testing, accuracy is key. MyHeritage DNA has been praised for its accuracy, but how does it compare to other DNA testing companies?

Let’s take a look:

Company Accuracy Genetic Variants Tested
MyHeritage DNA High 700,000
23andMe High 10 million
AncestryDNA High 15 million

As shown in the table above, MyHeritage DNA tests for around 700,000 genetic variants, while 23andMe and AncestryDNA test for 10 million and 15 million genetic variants, respectively.

However, it’s important to note that more genetic variants don’t necessarily mean more accurate results.

Overall, MyHeritage DNA has been praised for its accuracy and has received positive reviews from customers.

Keep in mind that no DNA test is 100% accurate and results can vary depending on a number of factors, including the quality of the DNA sample provided.

When it comes to accuracy, it’s also important to consider the company’s privacy policies and how they handle customer data.

MyHeritage DNA has multi-layered privacy protection and is committed to protecting its customers’ data.

Ultimately, when choosing a DNA testing company, it’s important to research and choose a reputable company you trust.


After researching various sources, it is clear that MyHeritage’s accuracy can vary depending on the individual’s DNA sample and the specific test being taken.

Some users have reported discrepancies in their results, while others have found the tests to be highly accurate.

While MyHeritage may not be as specific or accurate as some other DNA testing companies, such as 23andMe, it still offers valuable insights into an individual’s ethnicity and genealogy.

Additionally, MyHeritage’s multi-layered privacy protection ensures that users’ DNA data remains secure.

Ultimately, the decision to use MyHeritage for DNA testing should be based on individual preferences and needs.

Those interested in learning about their DNA matches or finding long-lost relatives may find MyHeritage to be a good option.

However, those seeking more comprehensive health testing or highly specific ancestry results may want to consider other options.
