      - LOINC provides codes of varying granularity (though not usefully more specific in this particular case) and more generic LOINCs  can be mapped to more specific codes as shown here

    Both is best, since it's not always possible to infer
    one from the other in code.

    When a computable unit is provided, UCUM (http://unitsofmeasure.org)
    is always preferred, but it doesn't provide notional units (such as
    "tablet"), etc. For these, something else is required (e.g. SNOMED CT)
