I did one last year and was told 72 percent of my ancestry comes from Great Britain. What puzzled me was that Eastern Europe only made up 2 percent of my ethnicity, since I have several sets of great-great-grandparents who immigrated to the US directly from Czechoslovakia. I would have thought that would make for more than 2-percent of my DNA. I’ve heard that if I sent my saliva to another testing company, the results would probably be a bit different. So how reliable are these tests, really? Consumer Guide to Genetic Tests
