Are Home DNA Tests as Accurate as They Seem?

At-home, one-size-fits all DNA tests are big business these days. It’s all but impossible to escape the endless barrage of DNA test ads infiltrating your Facebook timeline and television set alike. Hate to break it to you, but those ads aren’t going anywhere any time soon. The market for DNA testing is growing exponentially, with experts projecting that the world’s consumer genetic testing market to rise to $340 million by as early as 2022.

Today, we’re going to take a closer look at this surging new market in an effort to answer as many of your burning questions as possible. What are DNA tests? What can they tell you about yourself? Do they even work? Read on to find out more!

What is DNA?

You may have studied it in elementary level biology, but before we wade in to the muddy waters of DNA testing, here’s a little refresher.

“DNA” stands for deoxyribonucleic acid. This self-replicating material exists in almost all living organisms and acts as a carrier for genetic information. If you were a computer, your DNA would be your underlying code.

DNA, and its signature double-helix structure, was discovered in 1953 by James Watson and Francis Crick. Its discovery was monumental, though its secrets are far from entirely understood.

Though there’s a lot that we don’t know about your DNA, there’s plenty that we do know.
