Personal health information refers to demographic information, medical history, test and laboratory results, insurance information, and other data that a healthcare professional collects to identify an individual and determine appropriate care1. In the past decade or so, some of the tests and techniques used to collect personal health information have become publicly accessible. For example, private companies now offer genetic testing and genome sequencing to anyone able to pay. At the same time, there has been an explosion of wearable health monitoring devices. Given this revolution in personal health technology, important implications for individuals, the practice of medicine, and privacy must be considered.
