C.11 - EHDS refined base model for Observation performed by laboratory

LOINC, NPU

Laboratory test kit used during measurement.

Information about which end-user calibrator the laboratory has been used for the measurement to indicate the metrological traceability chain. 

Accreditation status of the laboratory for the particular observation.

Code system to be specified

Previous results of the same observation

C.11 - EHDS refined base model for Observation performed by laboratory

Date and time of the observation

Code representing the observation using the agreed code systems.

LOINC, NPU

Full name of the observation according to the used test coding standard.

Result of the observation including text, numeric and coded results of the measurement and measurement uncertainty. Content of the observation result will vary according to the type of the observation.

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

Identifies order and order placer this observation belongs to. 

Identifies the originator/author and provides provenance information about the source of the results data that may have not originated with the source of the whole Laboratory Report document. 

With certain observation results, e.g. there may also be an interpreter or a person responsible for validation.

A numeric value or interval (open or closed) of the result

Result units of the measurement

UCUM

Measurement uncertainty type and interval should be provided if needed.

A coded result from a selected coding system(s). This could be a code describing bacteria or other microorganism identified, description of urinary concernment, code explaining technical reason why the test could not be done etc.
