Within the context of the ISO/IEEE 11073? family of standards for device communication@ this standard establishes a normative defi nition of communication between personal telehealth urine analyzer devices and managers (e.g.@ cell phones@ personal computers@ personal health appliances@ set-top boxes) in a manner that enables plug-and-play interoperability. It leverages appropriate portions of existing standards including ISO/ IEEE 11073 terminology@ information models@ application profi le standards@ and transport standards. It specifi es the use of specifi c term codes@ formats@ and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability. This standard defi nes a common core of communication functionality for personal telehealth urine analyzers. Purpose This standard addresses a need for an openly defi ned@ independent standard for controlling information exchange to and from personal health devices and compute engines (e.g.@ cell phones@ personal computers@ personal health appliances@ and set-top boxes). Interoperability is the key to growing the potential market for these devices and to enabling people to be better informed participants in the management of their health.
