One or more codes specifying a rough qualitative interpretation of the observation, such as "normal", "abnormal", "below normal", "change up", "resistant", "susceptible", etc. OpenIssue: Description copied from Concept Domain of same name. Must be verified. Note also that this might be identical to the V2 code system of interpretation codes (formerly Abnormal Flags in older versions).
