    Observations are often coded in multiple code systems.
      - 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
      - snomed provides a clinically relevant code that is usually less granular than
   LOINC
      - the source system provides its own code, which may be less or more granular than
   LOINC

    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)
