This is a value set defined by the FHIR project. Related v3 content: v3 Code System ObservationInterpretation.
Codes identifying interpretations of observations
Formal definitions: XML or JSON.
This value set defines the set of codes that can be used to indicate the meaning/use of a reference range
This value set includes codes defined in other code systems, using the following rules:
Code | System | Display |

A | http://hl7.org/fhir/v2/0078 | Abnormal (applies to non-numeric results) |
AA | http://hl7.org/fhir/v2/0078 | Very abnormal (applies to non-numeric units, analogous to panic limits for numeric units) |
