Once in the agreed human representation, and once in a coded form. 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 &quot;tablet&quot;), etc. For these, something else is required (e.g. Snomed-CT) --> <!-- eH dataabsent reason would go here if valueQuantity was empty e.g.: &lt;dataAbsentReason value=&quot;error&quot;/&gt; --> </Observation> Usage note: every effort has been made to ensure that the examples are correct and useful, but they are not a normative part of the specification. © HL7.org 2011+.
