Can You Get a DNA Test Done for Free?

Yes, there are some ways to get a DNA test for free. However, these methods can have limitations or drawbacks that are important to consider. 

It’s also important to remember that there are different types of DNA tests, and you should be sure to learn which types are best suited to your needs.

What Are the Different Types of DNA Tests?

Before we get into free vs. paid DNA tests, it’s important to understand the different DNA tests and what they do. There are three types of genealogical tests that DNA testing companies usually provide:

  • Autosomal DNA tests – This analyzes autosomal DNA found in chromosomes from either biological sex. It can also give you information about your ancestry
  • Y-DNA tests – This analyzes DNA found in the Y chromosome and provides information on your father’s ancestry. It can only performed on biological males.
  • Mitochondrial DNA (mtDNA) test – This analyzes DNA found in the mitochondria and provides information on your mother’s ancestry. Since everyone has mtDNA, this test can be performed on either biological sex.

Free vs. Paid DNA Testing

Many companies offer paid DNA testing, which requires taking a DNA sample with a kit that you purchase.

There are also free options for DNA testing, but these usually require a copy of your raw DNA data. Some companies will allow you to upload your raw DNA data to their database, and they’ll interpret it for you for free.

One of the main limitations of free DNA tests is the need for raw DNA data. In most cases, you’ll have to pay for a DNA test kit from a DNA testing company.

What are Some Free DNA Test Analysis and Online Tools?

If you already have your raw DNA data, several services can analyze your DNA data for free, allowing you to get even more insights out of a DNA test. 

Most of these services will be done by analyzing your autosomal DNA. If you don’t have your raw DNA data, here’s a list of some ways to get free DNA test kits.

Major DNA Testing Company Tools

Many DNA testing companies sell DNA test kits and provide free DNA analysis if you already have a copy of your raw DNA data from another testing service.

For example, Family Tree DNA provides a family finder platform for free if you already have a copy of your raw DNA. You can upload your autosomal DNA data from other major testing companies to connect you with new relatives.

On the other hand, MyHeritage offers genetic genealogy tools that can be used without a copy of your raw DNA. They can help you build a family tree and research their ancestry database for free. However, viewing detailed results and access to DNA analysis will require a paid subscription.

Third-Party DNA Tools

In addition to DNA testing companies, there are also third-party services that don’t offer DNA test kits but will still offer free DNA analysis services if you have your raw DNA data.

One example is DNA Painter, which is dedicated to helping you understand your genetic genealogy in a deeper and more accessible way. One of their services is chromosomal mapping, which allows you to learn what parts of your DNA came from which of your ancestors.

Unlike other free tools, you don’t need to upload raw DNA data to DNA Painter. Instead, you will need to segment DNA.

DNA segmentation is offered by certain sites, including Family Tree DNA, GEDmatch, and MyHeritage. You will also need raw DNA data to get DNA segment data from these sites.

GEDmatch

GEDmatch is a popular free DNA analysis site with over 45 tools to help you learn about your ancestry and find relatives.

Their free tools can help you compare your genetic data with other users in their DNA database. You can also compare your DNA with individual users and learn more about your heritage in general.

DNAGedcom

DNAGedcom is a set of DNA analysis tools that allows you to manage genetic data from other sites and services.

Their tools allow you to gather your autosomal DNA data and data on people with matching DNA, family trees, and ethnicity. 

Once you have gathered all this data in one place, you can do a detailed analysis. This includes a DNA segment analysis, which allows you to discover which parts of your DNA you share with different relatives.

While creating an account is free, many of the DNAGedcom tools require a program to be installed on your computer, as well as a paid subscription to use this program.

How Accurate Are Free DNA Tests?

Like other DNA analysis services, free DNA tests can have varying degrees of accuracy.

Ethnicity results can vary between different services, potentially making learning about your ancestry confusing. Many of these tests are also not regulated, which means there is no research that can verify how accurate their claims are.

If you are worried about the accuracy of a free DNA test, you should consult an expert, especially when you are dealing with medical tests.

How to Get a Free DNA Test Kit

As mentioned before, you’ll need a DNA test kit to obtain a sample of your raw DNA. Although these kits usually cost money, there are some ways to get one for free or at a discount:

Special Promotions and Discounts

Major DNA testing companies like 23andme and AncestryDNA will sometimes offer discounts on their DNA test kits. 

To find these, you can check their social media accounts or search the web for existing promos and discounts.

DNA Testing for Research Purposes

Some ongoing research initiatives on genetics and health research can give free DNA tests in exchange for your data being used in studies. However, you need to meet certain criteria to be eligible for a free DNA test. 

For example, the All of Us Research Program seeks to understand the role of our genes in how and why diseases affect people differently. Anyone over 18 years old who is living in the United States is eligible to participate in All of Us. 

Once you provide a DNA sample, you’ll have access to information about your ancestry and how your DNA can affect your health on the All of Us platforms. They also intend to provide participants with their raw DNA data.

On the other hand, 23andMe’s Global Genetics Project hopes to increase the diversity of its DNA database to study the migration of people throughout history. You can join the program, but only people with certain ancestries are eligible. Check the list of countries on the Global Genetics Project website to see if you are eligible.

Community and Crowd-Sourced Projects

Several crowdfunded or community projects offer free DNA test kits to those who meet certain criteria.

The International Society of Genetic Genealogists keeps a list of projects offering free DNA tests for individuals with certain last names. However, many of these only offer Y-DNA tests, meaning only biological males are eligible.

DNA Quest is an initiative from MyHeritage that provides free DNA testing for adopted people who want to find their biological parents. The number of free tests is limited, but there is a waiting list that you can join.

What is the Purpose of DNA Testing?

Genetic genealogy can help you learn more about your ancestry and family tree.

It can also help you:

  • Determine where in the world your ancestors are from
  • Get a more detailed breakdown of your ethnic background
  • Learn about genetic conditions you may be at risk for
  • Learn about your family tree and find family members you may be unaware of
  • Assess genetic conditions during pregnancy

It is important to remember that while a DNA testing company can provide potentially helpful information regarding your health, DNA tests are not substitutes for clinical testing.

Any health-related results you get from these tests should be verified with further tests and consultations with a healthcare professional.

What to Consider Before Taking a DNA Test

DNA tests can be insightful and impactful, but there are several factors you should consider before taking a DNA test

  • Privacy and data security – You might not feel comfortable entrusting DNA analysis sites with extremely personal information about your family, health, and ancestry.
  • Test accuracy and reliability – One study examined 49 people who received a DNA test that indicated they were at risk of certain diseases. The study found that 40% of these cases were false positives.
  • Potential emotional impact – Although DNA test results can be interesting, they can impact your sense of identity. Finding out you’re at risk of certain diseases can also cause stress and anxiety.
