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 Ratios (observable entity) - v1.0”

The java implementation of this template can be found: https://github.com/IHTSDO/reporting-engine/blob/develop/script-engine/src/main/java/org/ihtsdo/termserver/scripting/pipeline/loinc/LoincTemplatedConceptWithRelative.java

Attributes

• 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 Relative To: Specifies what the observation is relative to.

LOINC Properties currently supported:  "NFr", "MFr", "CFr", "AFr", "VFr", "SFr"

Terming

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.

...

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