Examples include systolic and diastolic component observations for blood pressure measurement and multiple component observations for genetics observations.

Field Card. Type and Description 
code 1..1ConceptDescribes what was observed. Sometimes this is called the observation "code".Binding: LOINC Codes (Example)
dataAbsentReason 0..1ConceptProvides a reason why the expected value in the element Observation.value[x] is missing.Binding: Observation Value Absent Reason (Extensible)
id 0..1Stringunique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.interpretation 0..1ConceptThe assessment made based on the result of the observation. Intended as a simple compact code often placed adjacent to the result value in reports and flow sheets to signal the meaning/normalcy status of the result. Otherwise known as abnormal flag.Binding: Observation Interpretation Codes (Extensible)
referenceRange 0..*Element Guidance on how to interpret the value by comparison to a normal or recommended range.value[x] 0..1Interval<Quantity | Concept | String | Interval<Quantity> | Ratio | SampledData | Attachment | Time | DateTime | Interval<DateTime>The information determined as a result of making the observation, if the information has a simple value.Key: = Must support, = QICore-defined extension, = Is-Modifier
