How do we look at your DNA?
Your DNA insights start with a saliva sample. To see which markers you have, we analyze your DNA to estimate your lifetime risk for common health conditions.

Sometimes, certain markers can be hard to read correctly, but Navigenics analyzes your DNA until we get the most complete answer possible with our services. That's not always the case with other personal genetic testing companies. Navigenics is committed to comprehensive and thorough genetic analysis.
As new science reveals more connections between genetic markers and health conditions, depending on which of our services you choose, your DNA test results can be updated to include the most current information.
How do we know which markers are connected with particular health risks? The concept behind the science is fairly straightforward. Take thousands of people with a medical condition, and thousands of similar people who do not have that condition. Compare their DNA and identify places where one version of a marker is much more common among the affected people than the healthy people. Then we know those markers are either on or close to DNA that increases the risk of that condition.
