Represents measurements and assertions made regarding a patient or device. Observations are a central element in healthcare, used to support diagnosis, monitor progress, determine baselines and patterns, and even capture demographic characteristics.
This packaged object has a standard object counterpart in the Clinical Data Model. We recommend using the standard object because it’s more closely aligned with FHIR v4.0.
Fields
Account__c
Type: reference
Properties: Create, Filter, Group, Sort
Description: The person account that represents the patient in Lightning Platform.
Description: The time or time period when the observed value is asserted as being true, usually the time of a procedure or specimen collection. Often the source of the date or time isn’t known. Unless this observation is a historical report, a date is required.
Description: The system that defines the site on the patient’s body where the observation was made (also called the target site).
Comments__c
Type: textarea
Properties: Create, Nillable, Update
Description: Statements about significant, unexpected, or unreliable values—or information about the source of the observed value—that can be relevant to the interpretation of the result.
Description: The system-defined code that represents the assessment that’s made based on the observation results. For some results, especially numeric results, an interpretation is necessary to fully understand the significance of a result.
Description: The human-readable label that represents the assessment that’s made based on the result of the observation. For some results, especially numeric results, an interpretation is necessary to fully understand the significance of a result.

IsRestricted__c
Type: boolean
Properties: Create, Defaulted on create, Filter, Group, Sort, Update
Description: Indicates whether or not this field has restricted visibility based on sharing rules.
Description: The date and time when the observation was made available. Updated when the result is updated.
IsVisibleOnPatientCard__c
Type: boolean
Properties: Defaulted on create, Filter, Group
Description: Indicates whether or not this field appears on the patient card.
LastActivityDate
Type: date
Properties: Filter, Group, Nillable, Sort
Description: Whichever of the following is the most recent:
Due date of the most recent event logged against the record.
Due date of the most recently closed task associated with the record.
LastReferencedDate
Type: dateTime
Properties: Filter, Nillable, Sort
Description: The time stamp that indicates when the current user last viewed a related record.
LastViewedDate
Type: dateTime
Properties: Filter, Nillable, Sort
Description: The timestamp for when the current user last viewed this record. If this value is null, it’s possible that this record was referenced (LastReferencedDate) and not viewed.
Description: The system-defined code that represents the mechanism that’s used to perform the observation. In some cases, method can impact results and is therefore used to determine whether results can be compared or to determine the significance of results.

Name
Type: string
Properties: Autonumber, Defaulted on create, Filter, idLookup, Sort
Description: The EHR observation ID. Limit: 255 characters.
Description: The human-readable label that represents the meaning of the applicable reference range, which provides guidance on how to interpret the observed value by comparison to a normal or recommended range. Specify what kind of reference range it is (for example, normal, recommended, or therapeutic), or what state this reference range applies to (for example, age or hormonal cycles).
Description: The age at the high end of the applicable reference range. Can be a neonatal age (for example, number of weeks at term). If this element is omitted, the high value of the reference range is assumed to be meaningless (for example, the reference range is > 5). If the low comparator is missing , it’s assumed to be “<”.
Description: The age at the low end of the applicable reference range. Can be a neonatal age (for example, number of weeks at term). If this element is omitted, the low value of the reference range is assumed to be meaningless (for example, the reference range is < 2). If the high comparator is missing, it’s assumed to be “>”.
Description: The value at the high end of the applicable reference range. If this element is omitted, the high value of the reference range is assumed to be meaningless. (for example, the reference range is > 5). If the low comparator is missing, it’s assumed to be “<”.
Description: The value at the low end of the applicable reference range. If this element is omitted, the low value of the reference range is assumed to be meaningless. (for example, the reference range is < 2). If the high comparator is missing, it’s assumed to be “>”.
Description: The system-defined code that represents the meaning of the applicable reference range. Specify what kind of reference range it is (for example, normal, recommended, or therapeutic), or what state this reference range applies to (for example, age or hormonal cycles).
Description: An estimate of the degree to which quality issues have impacted the reported value. Picklist values: calibrating, early, error, ok, ongoing, and questionable.
Description: An attachment related to the observed value. Attachments include additional data content defined in other formats such as PDF, typically images or reports.
Description: The number of sample points at each time point in the sampled data. If this value is greater than one, all sample points for a point in time are recorded at the same time.
Description: The lower limit of detection of the measured points in the sampled data. Required if any data points have the value L (lower than detection limit).
Description: The base quantity that a measured value of zero represents in the sampled data. This value provides the units of the entire measurement series.
Description: The system that defines the information determined by making the observation, if the information has a simple value.
Usage
Most observations are simple name-value pair assertions with some metadata, but some observations group other observations together logically, or even are multicomponent observations.
