# Impression Observable

This template is employed when the LOINC term represents an impression observable, capturing a high-level clinical interpretation or summary derived from one or more observations, rather than a direct measurement or finding.

Impression observables concepts all have a primitive definition, following the template described below and documented here: [Impression observable for LOINC (observable entity) - v1.0](https://conf.spaces.snomed.org/wiki/spaces/SCTEMPLATES/pages/484769793/Impression+observable+for+LOINC+observable+entity+-+v1.0).

## Attributes <a href="#id-4.2.1qualityobservablewithcomponent-attributes" id="id-4.2.1qualityobservablewithcomponent-attributes"></a>

* **LOINC Property**: indicates that the quality being observered is some impression or interpretation.

This template is utilized when the LOINC term represents an impression observable.

### Model <a href="#id-4.2.1qualityobservablewithcomponent-model" id="id-4.2.1qualityobservablewithcomponent-model"></a>

{% code overflow="wrap" %}

```
<<< 363787002 |Observable entity (observable entity)| :

### Terming <a href="#id-4.2.1qualityobservablewithcomponent-terming" id="id-4.2.1qualityobservablewithcomponent-terming"></a>

In the case of impression concept, the  LOINC Long Common Name is used  as both the FSN (with a semantic tag of "(observable entity)" added), and the Preferred Term.  The LOINC Short Common Name is also included unchanged as an acceptable synonym.&#x20;

In the case of the example below, this results in the following terms:
