The company 23andMe provides personal genetic testing from a convenient home saliva sample kit. Their home page indicates that their $99 genetic screening will provide reports on 240+ health conditions in addition to giving you information on your genetic lineage. The benefits, they claim, are that you will learn about your carrier status and therefore the risk of passing on genetic diseases to your children. The information will also inform you about health risks so that you can change your behavior to manage them. Finally the genetic information will tell you about how you might respond to different drugs so that you can “arm your doctor with information.”
The home page also contains a link to testimonials about how their DNA testing has changed people’s lives.
