# 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).

The java implementation of this template can be found [here](https://github.com/IHTSDO/script-library/blob/develop/src/main/java/org/ihtsdo/termserver/scripting/pipeline/loinc/template/LoincTemplatedConceptWithSusceptibility.java).

## 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.

## Template <a href="#id-4.2.1qualityobservablewithcomponent-template" id="id-4.2.1qualityobservablewithcomponent-template"></a>

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)| : 
{ 370130000 |Property (attribute)| -> 118580000 |Impression AND/OR interpretation of study (property) (qualifier value)| }
```

{% endcode %}

### 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:

#### LOINC Term [100695-6](https://loinc.org/100695-6/)

There are no LOINC parts represented in the SNOMED model for these impression concepts.   The SNOMED concepts are defined as primitive, with only the single property attribute present, always taking a value of 118580000 |Impression AND/OR interpretation of study (property).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.snomed.org/implementation-guides/loinc-implementation-guide/content-development/4.2-template-based-content-creation/4.2.1-quality-observable-with-component-1.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
