Sure you can track your health data, but can your doctor use it?

Dr. Paul Abramson is no technophobe. He works at a hydraulic standing desk made in Denmark and his stethoscope boasts a data screen. "I'm an engineer and I'm in health care," he says. "I like gadgets." Still, the proliferation of gadgets that collect health data are giving him pause. Abramson is a primary care doctor in San Francisco and lots of his patients work in the tech industry. So it's not surprising that more and more of them are coming in with information collected from consumer medical devices — you know, those wristbands and phone apps that measure how much exercise you're getting or how many calories you're eating.
