### Logical Definition (CLD)

- Include these codes as defined in `http://hl7.org/fhir/observation-status` version 📦4.0.1

  Code | Display | Definition
  registered | Registered | The existence of the observation is registered, but there is no result yet available.
  preliminary | Preliminary | This is an initial or interim observation: data may be incomplete or unverified.
  final | Final | The observation is complete and there are no further actions needed. Additional information such "released", "signed", etc would be represented using [Provenance](provenance.html) which provides not only the act but also the actors and dates and other related data. These act states would be associated with an observation status of `preliminary` until they are all completed and then a status of `final` would be applied.
  amended | Amended | Subsequent to being Final, the observation has been modified subsequent. This includes updates/new information and corrections.
  corrected | Corrected | Subsequent to being Final, the observation has been modified to correct an error in the test result.
  entered-in-error | Entered in Error | The observation has been withdrawn following previous final release.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".).
  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.
