Is genetic testing really worth the money?
Worried that your genes predispose you to developing diabetes or some other disease? Or maybe you’re just curious as to whether your DNA is going to give better-than-average chance of living past 90.
For prices ranging from $200 to close to $1,000, that information can be yours in a matter of days, according to a growing number of genetic-testing companies now pushing their services online.
Sites such as 23andMe, FirstMark ONC, and Navigenics merely require a small saliva sample, advertsing that their results provide information about risk factors for up to 95 diseases and predicted responses to drugs.
The sites suggest that worried consumers will benefit through better understanding their health risks, leading them to smarter decisions and healthier lifestyles.
But, are they worth the money? Probably not, according to a recent study in the New England Journal of Medicine.
