ValueSet
Expansion performed internally based on codesystem Observation Reference Range Meaning Codes v1.0.1 (CodeSystem) 
This value set contains 13 concepts
| Level | Code | System | Display | Definition | 
| 1 | type  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Type | General types of reference range. | 
| 2 | normal  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Normal Range | Values 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  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Recommended Range | The range that is recommended by a relevant professional body. | 
| 2 | treatment  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Treatment Range | The range at which treatment would/should be considered. | 
| 2 | therapeutic  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Therapeutic Desired Level | The optimal range for best therapeutic outcomes. | 
| 3 | pre  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Pre Therapeutic Desired Level | The optimal range for best therapeutic outcomes for a specimen taken immediately before administration. | 
| 3 | post  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Post Therapeutic Desired Level | The optimal range for best therapeutic outcomes for a specimen taken immediately after administration. | 
| 1 | endocrine  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Endocrine | Endocrine related states that change the expected value. | 
| 2 | pre-puberty  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Pre-Puberty | An expected range in an individual prior to puberty. | 
| 2 | follicular  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Follicular Stage | An expected range in an individual during the follicular stage of the cycle. | 
| 2 | midcycle  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | MidCycle | An expected range in an individual during the midcycle stage of the cycle. | 
| 2 | luteal  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Luteal | An expected range in an individual during the luteal stage of the cycle. | 
| 2 | postmenopausal  | http://terminology.hl7.org/CodeSystem/referencerange-meaning | Post-Menopause | An expected range in an individual post-menopause. |

Explanation of the columns that may appear on this page:
| Lvl | A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information | 
| Source | The source of the definition of the code (when the value set draws in codes defined elsewhere) | 
| Code | The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract') | 
| Display | The 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 | 
| Definition | An explanation of the meaning of the concept | 
| Comments | Additional notes about how to use the code |
