Field Card. Type and Description 
age 0..1interval<Quantity>The age at which this reference range is applicable. This is a neonatal age (e.g. number of weeks at term) if the meaning says so.high 0..1QuantityThe value of the high bound of the reference range. The high bound of the reference range endpoint is inclusive of the value (e.g. reference range is >=5 - <=9). If the high bound is omitted, it is assumed to be meaningless (e.g. reference range is >= 2.3).id 0..1Stringunique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.low 0..1QuantityThe value of the low bound of the reference range. The low bound of the reference range endpoint is inclusive of the value (e.g. reference range is >=5 - <=9). If the low bound is omitted, it is assumed to be meaningless (e.g. reference range is <=2.3).meaning 0..*List<Concept>Codes to indicate the the target population this reference range applies to. For example, a reference range may be based on the normal population or a particular sex, race, therapeutic status, or endocrine or reproductive status.Binding: Observation Reference Range Meaning Codes (Example)
text 0..1StringText based reference range in an observation which may be used when a quantitative range is not appropriate for an observation. An example would be a reference value of "Negative" or a list or table of 'normals'.Key: = Must support, = QICore-defined extension, = Is-Modifier
