 header | | | | |
 subject | O | 1..1 | EHDSPatient | Patient who is receiving health care. This patient might be different from the direct subject of the observation. |

| observationDate[x] | O | 1..1 | dateTime, Period | Clinically relevant time or time period for the observation |
| type | O | 1..1 | CodeableConcept | Observation type. Code and name representing the type of the observation using the agreed code systems. |
| result | O | 1..1 | Base | Result of the observation including text, numeric, coded, and other types of results of the measurement and measurement uncertainty. Content of the observation result will vary according to the type of the observation. |
| value[x] | O | 0..1 | string, Quantity, Range, Ratio, CodeableConcept | Observation result value according to the type of observation. Model covers only most frequently used data types but other data types can be used as well.
Text result value should be used only if coded result value is not expected otherwise use valueCodeableConcept.text. For Quantity, Range and Ratio, result units of the measurement should be provided. |
| note | O | 0..1 | string | Comments and narrative representation of the observation result and findings. |
| component | O | 0..* | Base | Component in case the observation consists of multiple sub-observations (e.g. blood pressure). |
 code | O | 1..1 | CodeableConcept | Code representing the observation using the agreed code systems. |
| result | O | 1..1 | Base | Result of the observation including text, numeric, coded, and other types of results of the measurement and measurement uncertainty. Content of the observation result will vary according to the type of the observation. |
