  Code	Display	Definition
  registered	Registered	The existence of the observation is registered, but there is no result yet available.
  cancelled	Cancelled	The observation is unavailable because the measurement was not started or not completed (also sometimes called "aborted").
  unknown	Unknown	The authoring/source system does not know which of the status values currently applies for this observation. Note: This concept is not to be used for "other" - one of the listed statuses is presumed to apply, but the authoring/source system does not know which.
  entered-in-error	Entered in Error	The observation has been withdrawn following previous final release. This electronic record should never have existed, though it is possible that real-world decisions were based on it. (If real-world activity has occurred, the status should be "cancelled" rather than "entered-in-error".).
