They used to have a service for exactly that: http://www.google.com/intl/en_us/health/about/

I worked for a startup in the electronic medical records space. Data interchange.

We had various interactions with both the Google Health and Microsoft HealthVault teams. They were both making patient facing apps, ours was physician (and staff) facing.

We had a patient facing app, because all the hospitals thought it'd drive admissions.

But at the time no doctor would trust patient's data.

To the best of my knowledge, that hasn't changed (five years on).

The "quantified self" movement may change the perception of patient gathered data. When data collection is automatic, standardized. More importantly, when doctors are doing it for themselves, so are familiar with the tools and culture.

So, in short, Google Health and MS HealthVault were just wishful thinking. There was no "there" there.

Calico is a different company, so if some day you decide to give them access to your medical records, that won't automatically give access to google.

Yeah, then I guess they will just show you an annoying pop-up every now and then, basically pushing you to merge your Calico account into you Google account.

There are very specific laws in place in the US that make this more than unlikely, probably illegal. I sincerely doubt Google wants HIPAA to start applying to far more of their business and data.
