Google Health has been designed as a PHR (Personal Health Record), but it is also a bit of a different model. “We believe it’s not enough to offer a place where you can store, manage, and share your health information. You need to act on your health information to better manage your health needs on a daily basis. This is why we provide a directory of online health services to you. You must elect to sign up with a service and decide what level of personal data you want to share in exchange for the customized services those companies offer”, is mentioned on Google Health pages.
