Data Type Profile: Quantity (MyHealth@EU)

This profile of the Quantity data type constraints the Quantity (MyHealth@EU) profile defining a core value set for UCUM. The Quantity (MyHealth@EU) imposes the usage of the UCUM as the code system for units and allows expressing uncertainty of measurement.

This profile of the Quantity data type imposes the usage of the UCUM as the code system for units and allows expressing uncertainty of measurement

Usages:

• Derived from this DataType Profile: Simple Quantity (MyHealth@EU)
• Use this DataType Profile: Ratio (MyHealth@EU) and Observation: Medical Test Result (Core)
