Myth: DNA Testing is 100% Accurate

One common misconception is that DNA testing provides completely accurate results. While these tests are highly reliable, they are not infallible. Factors such as sample contamination or limitations in the current genetic databases can affect outcomes. It's crucial to understand that DNA testing offers probabilities rather than absolute certainties.

The Role of Databases

DNA testing companies compare your genetic information against their databases to provide results. The accuracy of these results often depends on the size and diversity of the database. A larger and more diverse database can yield more precise insights into your ancestry and potential health risks.

Myth: Your DNA Test Results are Private

Many believe that their DNA test results are completely private. However, it's important to read the privacy policies of the testing companies. Some companies may share data with third parties or use it for research purposes. Always ensure you understand how your genetic data will be handled before proceeding with a test.
