23andMe Genetic DNA Testing and Analysis
23andMe is a genetic testing service available directly to you from home that includes over 60 personalized genetic reports covering ancestry, wellness (such as lactose intolerance, and sleep issues), genetic traits (such as hair loss), and "carrier" status for a wide range of conditions. All carrier status tests meet FDA criteria for being scientifically and clinically valid. The process is simple, you use a home based saliva collection kit, pop it in the post, and get your reports online.
You can even find out what percentage of your DNA comes from Neanderthals!
