These results raise questions many people ask (or should ask) when they approach the multibillion-dollar business of home DNA tests, which are readily available online:
Are they accurate?
Are they worth the money?
What good is the information?
I spoke with a number of geneticists, and the consensus was that you should approach home DNA tests with a degree of skepticism. It’s not that the test results are routinely wrong. It’s more that they may not be entirely right.

As with the ancestry results, maybe some of [medical DNA test] findings will be spot on. But do you really want to start planning for a future with Lou Gehrig’s disease based on a $100 test kit purchased through Amazon?
“I’d always get a second opinion,” Krimsky said.
