Data Type Profile: Quantity: Laboratory

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

Usage:

• Use this DataType Constraint: Observation Results: Laboratory and Ratio: Laboratory
