Genetic tests give consumers hints about disease risk; critics have misgivings

Washington Post, January 26, 2010

Advocates of direct-to-consumer genotyping say these services can guide people toward appropriate preventive medical care, help them choose medications, and motivate them to make lifestyle changes.
