Requirements Need a framework for handling measures where the value is <5ug/L or >400mg/L due to the limitations of measuring methodology.

Comments The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system.
