Deciphering DNA Test Results: A Beginner’s Guide

Deciphering DNA Test Results: A Beginner’s Guide

DNA tests have grown in popularity over the years, offering insights into ancestry, health predispositions, and even personal traits. Whether you’ve taken a DNA test out of curiosity or for medical reasons, understanding the results can be both exciting and a bit overwhelming. This guide aims to give you information on how to understand a DNA test result panel and make sense of your findings.

1. Ancestral Breakdown: A Trip Back in Time

Most commercial DNA tests offer an ancestral breakdown. This section will reveal:

  • Percentage breakdown of your ethnic makeup, showing which global regions your ancestors hailed from.
  • Migration patterns: Some tests will show how your ancestors might have migrated over the centuries.
  • Relative connections: Many platforms connect you with potential relatives based on shared DNA segments.

Tip: Remember that borders and nations have changed over time. A result indicating “10% Italian,” for instance, could very well be linked to broader regions that historically shared populations with Italy.

2. Health Insights: Peering into Your Wellness Future

Some DNA tests provide health-related information, which might include:

  • Genetic risk factors: These results indicate if you have genetic markers associated with certain health conditions. However, having a marker does not guarantee you’ll develop the condition, and not having it doesn’t mean you’re immune.
  • Carrier status: This reveals if you’re a carrier for certain inherited conditions, which could be important if you’re planning to have children.

Tip: It’s crucial to consult with a genetic counselor or healthcare professional about health-related findings. They can provide context and advise on any necessary steps.

3. Personal Traits and Talents: The Fun Stuff

Some tests delve into the genes associated with personal traits. You might discover:

  • Taste preferences: Why you might love or hate cilantro, for instance.
  • Physical attributes: Such as the likelihood of having a unibrow or being lactose intolerant.
  • Talents or predispositions: Like having a genetic inclination towards being a morning person or having a higher endurance capacity.

Tip: While these insights are fun, they are often based on current research, which can evolve. Always take such results with a grain of salt.

4. Raw Data: Dive Deeper if You Dare

Most testing companies allow you to download your raw DNA data. This data:

  • Is a detailed record of your DNA, usually provided in a text format.
  • Can be uploaded to third-party platforms for further analysis, offering different insights or health information.

Tip: Always exercise caution when sharing your raw DNA data with third-party platforms. Ensure you understand the privacy policies and potential risks.

5. Privacy Considerations: Keeping Your Data Safe

Your DNA data is sensitive information. Consider the following:

  • Opt-out options: Some companies might share your anonymized data for research. Check if you can opt out.
  • Data storage: Learn how the testing company stores and protects your data. Can you delete your data if desired?
  • Third-party sharing: If connecting with relatives, be aware that messages or shared family trees might be accessible to the platform.


Decoding DNA test results can be a journey of self-discovery, offering a deeper understanding of your heritage and potential health. Always approach the results with an open mind, consult professionals for health-related insights, and prioritize your privacy. With these steps, you’re well on your way to making the most of your DNA test experience.
