Frequently Asked Questions

What is DNA testing?

DNA testing is the process of analyzing a person's genetic material to identify variations that may influence disease, health, traits, or response to medications. Tests range from targeted single gene panels to whole genome sequencing.

What is whole genome sequencing?

Whole genome sequencing (WGS) reads all of a person's three billion DNA base pairs, providing the most complete view of an individual's genetic code. Unlike targeted tests, WGS data can be reanalyzed as new genetic discoveries emerge.

How is DNA analysis different from DNA testing?

DNA testing generates raw genetic data from a sample. DNA analysis is the interpretation of that data into meaningful insights about ancestry, health risks, wellness traits, and more.

Is DNA testing safe and private?

Reputable providers use encryption, secure storage, and strict access controls to protect genetic data. Always review a provider's privacy policy and confirm that you control how your data is shared and used.

Do I need a science background to use DNA 101?

No. DNA 101 is written for beginners and explains genetic testing concepts in plain language so anyone can understand and apply the information.

How can I use my DNA results?

DNA results can inform decisions about nutrition, fitness, supplements, preventive screenings, family planning, and lifestyle choices. They can also be reanalyzed over time as scientific knowledge expands.

Can I upload existing DNA data?

Yes. Sequencing accepts uploads of existing DNA data from many popular testing providers, allowing you to access additional reports and insights without retesting.
