IPhone application for judging blood pressure and glucose
http://adage.com/digital/article?article_id=136991
Brief description:
The article is about a potential iPhone application that would check a user’s blood pressure and glucose with the help of a medical device, glucometer. LifeScan, a Jonhson & Johnson company that makes diabetes products, introduced a prototype for this application that would allow diabetics to interface their glucometers (which track blood-sugar levels) with the iPhone. The glucometer would measure a consumer's sugar, and the iPhone app would interpret and chart the results, calculate sugar intake during meals, and allow the user to better adjust his or her diabetes medications and diet accordingly. Additionally, the results could also be sent to a physician who would analyze them further if needed.

Use case for this technology: Judging the blood pressure and forwarding the reading to a physician:
The use case could be that the user makes use of the glucometer device to record the sugar level in his blood. The user then connects the device to his iPhone which reads the data and helps interpret the results in terms of calculating sugar intake and allowing user to better adjust his eating habits as suited for his health. The data could also be transferred to a physician who might do further sophisticated calculations with it.
Role of standards:
The article mentions no role of standards in this application. However, it is apparent that the standardized methods of measuring sugar levels are used for communicating the information.
