Data Type Profile: Ratio: Laboratory

This profile of the Ratio data type constraints the Ratio (Eu Lab) profile defining a core value set for UCUM. The Ratio (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
