Home DNA Testing Worth It?

23andmeHow badly do you want to be aware of your genetic predisposition to a condition? This is the at-home benefit of a company like 23 and ME – a private readout of your genetic vulnerabilities. But a study finds that these tests are wrong about 40% of the time.

Although it’s alluring to know more about your ancestry and all the long-lost stories you’ll never hear, the home DNA test really are not the crystal ball you’d like to think.

Tests offered by 23 and Me are informative for a ballpark figure of your pedigree and maybe a few laughs at a get together but betting the farm of any DNA reliability is a no-no.

Any medical test runs the possibility of kicking back a false positive result. When it comes to the at-home DNA testing kits, that likelihood is more like 44% erroneous results.

So if you’re definitely worried-enough to find-out if you’re positive for the BRCA1 gene, see a doctor. But if you want to throw a get-together fact checking your friends on their claims of heritage – drum-roll please. Keep this for entertainment purposes, only.
