23andMe：23andMe DNA Ancestry Test Kit

We have a high confidence in the accuracy of your results and the science behind them. Our scientists test and validate each step of the process we use to estimate our customers ancestry percentages. Importantly, we are transparent about the results of these tests, and you can read about it in our Ancestry Composition Guide[1].

Your 23andMe reports will tell you about your genetic ancestry, and you may learn that you share recent ancestors with a group of people who identify as belonging to a particular ethnic group. However, DNA cannot estimate your “ethnicity” or your “race,” because understandings of these concepts are socially constructed and depend on context, place, and time. We recommend that you use your genetic reports together with your family history to build a complete understanding of your ancestry.
