# Quality Observable with Relative to

This template is used when the LOINC term involves a component and is relative to something else, such as a reference point or another component.

This template is documented in Confluence here: [Quality observable with Component and Relative to for LOINC (observable entity) - v1.0](/implementation-guides/loinc-implementation-guide/content-development/4.2-template-based-content-creation/quality-observable-with-component-for-loinc-grouper.md)”

The java implementation of this template can be found [here](https://github.com/IHTSDO/reporting-engine/tree/7.9.2/script-engine/src/main/java/org/ihtsdo/termserver/scripting/pipeline/loinc/template/LoincTemplatedConceptWithRelative.java).

## Attributes <a href="#id-4.2.6qualityobservablewithrelativeto-attributes" id="id-4.2.6qualityobservablewithrelativeto-attributes"></a>

* **LOINC Property**: Represents the property of the observation, such as mass concentration or presence.
* **LOINC Scale**: Describes the scale type, like quantitative or qualitative.
* **LOINC Time**: Indicates the time aspect of the observation, e.g., single point in time.
* **LOINC System**: Specifies the direct site of the observation.
* **LOINC Method**: Describes the technique used for the observation.
* **LOINC Component**: Represents the specific component being measured or observed.
* **LOINC Divisor**: Specifies what the observation is relative to.

### Terming <a href="#id-4.2.6qualityobservablewithrelativeto-terming" id="id-4.2.6qualityobservablewithrelativeto-terming"></a>

Template slots are filled by taking the preferred term of the relevant value from the model and making the initial character lower case, if allowed by the case significance setting of the preferred term.

\[PROPERTY] of \[COMPONENT] to \[DIVISORS] in \[SYSTEM] at \[TIME] by \[METHOD] using \[DEVICE] \[CHALLENGE]

Some slots are optional, and are then tidied up along with any linking words (eg 'using')

The LOINC Long Common Name is specified as the Preferred Term and the LOINC Short Common Name is also included unchanged as an acceptable synonym. Finally a terse form of the LOINC Parts is added, with all part names specified, separated by colons.

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