As a 19-year-old sophomore at Stanford, Elizabeth Holmes decided to transform diagnostic medicine so she dropped out of college and used her tuition money to start her own company, Theranos. Ten years later, Holmes, pictured here holding a micro-vial, is on the cutting edge of medical technology — her new blood testing method allows hundreds of tests to be run using only a few drops of blood. And, Holmes’ methods are cheaper, faster, more accurate, and less invasive than conventional methods which often require a separate vial of blood for every test. As Holmes told Wired.com earlier this year, “I started this company because I wanted to spend my life changing our health care system. When someone you love gets really sick, most of the time when you find out, it’s too late to be able to do something about it. It’s heartbreaking… We wanted to make actionable health information accessible to people everywhere at the time it matters most. That means two things: being able to detect conditions in time to do something about them and providing access to information that can empower people to improve their lives.”

Her tests will revolutionize the public health world as we know it; Making diagnostic testing accessible and affordable for more people (and potentially saving Medicare and Medicaid ~$100 billion each over the next decade). (x)
