The at Home DNA Test Craze is Putting us All at Risk

At-home DNA ancestry tests have become hugely popular in recent years. More than 26 million have taken one of these tests. If their marketing is to be believed, they can help you learn where your DNA comes from, and even where your ancestors lived. But the information that can be inferred from your DNA is actually much more limited than testing companies are letting on. And that has lead consumers to misinterpret their results, which is having negative consequences.
