How reliable are DNA ancestry tests? Everything you need to know
Learning about one’s roots is one of the most important quests in life. And when we say our roots, we don’t mean just the origin of our grandparents, but something much deeper.
To learn what the specific genetic journey of our family is, how ancient civilizations, population migrations, and historical events shaped who we are today.
No matter how distant this may sound, the progress of science is such that with a simple saliva sample you can learn everything you want to know about your DNA—who you are, what percentage of Neanderthal DNA you have, and how your genes trace back to different countries or even continents.
Does it sound unbelievable? Read below to find out how the pioneering ethnicity DNA test works and what it offers you, and discover things about yourself you never imagined!
Article Summary
The search for our origins concerns the genetic journey of a family across thousands of years of history, migrations, and cultures. With a simple saliva sample, the ancestry DNA test reveals your genetic identity, your Neanderthal DNA percentage, and the regions of the world with which you share a common genetic heritage.
The test examines:
- Geographical ancestry compared with global databases
- Maternal line (mtDNA) up to 150,000 years back
- Paternal line (Y-DNA) for men, up to 250,000 years back
- Percentage of Neanderthal DNA and its significance
Its reliability is ensured by a laboratory with ISO 17025 certification, SNP/NGS technology, large European databases, and full GDPR compliance.
What will you learn from an ancestry DNA test?

The test examines genetic markers, meaning small pieces of information within the DNA that show from which populations and regions your ancestry originates, as well as your genealogical line thousands of years back.
Specifically, the test examines the following factors:
- Geographical ancestry: How much DNA you have from different regions (e.g., Balkans, Italy, North Africa), by comparing your DNA with large databases from around the world.
- Maternal genealogical line (mtDNA): It examines the DNA inherited exclusively from your mother—and from all mothers before her—showing where your maternal ancestors began and how they migrated over the past 150,000 years.
- Paternal genealogical line (Y-DNA): If you are male, the test analyzes the Y chromosome passed from father to son, revealing the path of the paternal family up to 250,000 years back.
- Neanderthal DNA percentage: Shows how much Neanderthal DNA you carry (usually 1–4%) and what this means.
Simply put, with an ancestry DNA test you learn a complete and understandable story of your origins, since behind the percentages lies an entire sequence of historical events that influenced the journey of your lineage and shaped who you are today.
