Properties

CodeTypeDescription
abstractbooleanTrue if an element is considered 'abstract' - in otherwords, the code is not for use as a real concept

This code system http://terminology.hl7.org/CodeSystem/referencerange-meaning defines the following codes:

LvlCodeDisplayDefinitionabstract
1type TypeGeneral types of reference range.true
2  normal Normal RangeValues expected for a normal member of the relevant control population being measured. Typically each results producer such as a laboratory has specific normal ranges and they are usually defined as within two standard deviations from the mean and account for 95.45% of this population.
2  recommended Recommended RangeThe range that is recommended by a relevant professional body.
2  treatment Treatment RangeThe range at which treatment would/should be considered.
2  therapeutic Therapeutic Desired LevelThe optimal range for best therapeutic outcomes.
3    pre Pre Therapeutic Desired LevelThe optimal range for best therapeutic outcomes for a specimen taken immediately before administration.
3    post Post Therapeutic Desired LevelThe optimal range for best therapeutic outcomes for a specimen taken immediately after administration.
1endocrine EndocrineEndocrine related states that change the expected value.true
2  pre-puberty Pre-PubertyAn expected range in an individual prior to puberty.
2  follicular Follicular StageAn expected range in an individual during the follicular stage of the cycle.
2  midcycle MidCycleAn expected range in an individual during the midcycle stage of the cycle.
2  luteal LutealAn expected range in an individual during the luteal stage of the cycle.
2  postmenopausal Post-MenopauseAn expected range in an individual post-menopause.

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
