Mail-in DNA test results bring surprises about family history for many users


About one-in-seven U.S. adults (15%) say they have used a mail-in DNA testing service from a company such as AncestryDNA or 23andMe, according to a new Pew Research Center survey. Most of them say they did so to learn more about their family origins, and a notable share say the results surprised them.

When asked about their reasons for using a mail-in DNA testing service, the vast majority of those who have done so (87%) say they wanted to learn more about where their family came from. About a third say they did so to get information about their health or family medical history (36%) and to connect with relatives they might have but didn’t know about (also 36%).
