Description
Identify a clinical unit code by its namespace and version.
Health-information systems separate identifiers, code-system namespaces, source versions, missing-value states and reference syntax. Recording a mapping or recognizing a restricted token does not validate its clinical meaning or a complete HL7/FHIR resource. Explicit null, empty text, unknown status and numeric zero are different states.
Identify a clinical unit code by its namespace and version.
When to use this tool
Use Clinical Unit Code Namespace Label when checking the stated restricted health-data record, token or transition convention.
How to use the tool and how it works
- Enter unitCode, namespace, version. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read token. Use the output convention below.
Require nonempty clinical unit code, namespace and version. Encode the ordered tuple as JSON text.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| unitCode | Unit Code | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| namespace | Namespace | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| version | Literal version text; no semantic ordering or current-version lookup. | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| token | JSON-encoded ordered tuple or literal token under the convention above; not a database lookup or authentication result. | Required. Text; maximum UTF-16 length 8192. |

"input": {
"unitCode": "mg",
"namespace": "http://unitsofmeasure.org",
"version": "2.2"
},
"output": {
"token": "[\"mg\",\"http://unitsofmeasure.org\",\"2.2\"]"
}
}Limitations and assumptions
- This does not validate a UCUM or local unit code, convert a result or establish dimensional compatibility.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use the intended complete interoperability specification, authoritative terminology and verified source records for actual resource validation, semantic mapping or clinical use.
