I was expecting to get some Native American results in my DNA and not in a million years and Balkans, Eastern Europe, or Middle East ones. I wonder what happened.

I see some people on here are puzzled about the Middle Eastern results too.

My grandmother considered herself Irish-Native American. I am African-American, and my results were indeed 72% Africa, 23% Europe with 12% Ireland. It's the remaining Europe and trace which puzzles me.

Why no Native America but totally unexpected Balkan and Middle East? Is the test flawed?
