description:
One or more codes specifying a rough qualitative interpretation of the observation,
such as "normal", "abnormal", "below normal", "change up", "resistant", "susceptible",
etc.
Discussion: These interpretation codes are sometimes called "abnormal flags", however, the judgment
of normalcy is just one of the common rough interpretations, and is often not relevant.
For example, the susceptibility interpretations are not about "normalcy", and for
any observation of a pathologic condition, it does not make sense to state the normalcy,
since
pathologic conditions are never considered "normal."
