Range is a set of ordered Quantity values defined by a low and high limit. A Range specifies a set of possible values and usually one value from the range applies (e.g. “give the patient between 2 and 4 tablets”). Ranges are typically used in instructions.


The unit and code/system elements of the low or high elements should match. If the low or high elements are missing, the meaning is that the low or high boundaries are not known and therefore neither is the complete range. The comparator flag on the low or high elements cannot be present.It is to be noted that the Range type should not be used to represent out of range measurements. A quantity type with the comparator element should be used instead.

Fast Healthcare Interoperability Resources (FHIR) is a draft standard describing data formats and elements (known as “resources”) and an application programming interface (API) for exchanging electronic health records. The standard was created by the Health Level Seven International (HL7) health-care standards organization.

Its goal is to facilitate interoperation between legacy healthcare systems, to make it easy to provide healthcare information to healthcare providers and individuals on a wide variety of devices from computers to tablets to cell phones, and to allow third-party application developers to provide medical applications which can be easily integrated into existing systems.

FHIR provides an alternative to document-centric approaches by directly exposing discrete data elements as services. For example, basic elements of healthcare like patients, admissions, diagnostic reports and medications can each be retrieved and manipulated via their own resource URLs (Uniform Resource Locators). FHIR was supported at an American Medical Informatics Association meeting by many EHR (Electronic Health Record) vendors which value its open and extensible nature.

Concept_NameName of the concept in the FHIR structurestringrequired : 1
Computer_Ready_NameA Computer-ready name (e.g. a token) that identifies the structure - suitable for code generation. Note that this name (and other names relevant for code generation, including element & slice names, codes etc) may collide with reserved words in the relevant target language, and code generators will need to handle this.string-
TypeThe type the structure describes.string-
Dollar_RefThe Dollar_Ref ($ref) string value contains a Uniform Resource Identifier (URI) which identifies the location of the JSON (JavaScript Object Notation) value being referenced.string-
DescriptionA free text natural language description of the structure and its usestring-
ItemsThe value of the keyword should be an object or an array of objects. If the keyword value is an object, then for the data array to be valid each item of the array should be valid according to the schema in this value.string-
Concept NameComputer Ready NameTypeDollar RefDescriptionItems
Rangeid#/definitions/stringUnique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
RangeextensionarrayMay be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable
Rangelow#/definitions/QuantityThe low limit. The boundary is inclusive.
Rangehigh#/definitions/QuantityThe high limit. The boundary is inclusive.
