Description
Return exactMatch and caseOnlyDifference when unequal spellings become equal under JavaScript lowercase.
Clinical exchange formats use exact delimiters, character grammars, and scoped identifiers. A local token check addresses one syntax condition and can succeed without validating a complete message or its clinical meaning.
Return exactMatch and caseOnlyDifference when unequal spellings become equal under JavaScript lowercase.
When to use this tool
Use Clinical Unit Case Sensitive Prefix Tag when you need one bounded spelling, delimiter, or identifier component.
How to use the tool and how it works
- Enter firstUnit, secondUnit. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read exactMatch, caseOnlyDifference. Inspect exactMatch, caseOnlyDifference before interpreting the associated values.
Require nonempty firstUnit and secondUnit. Return exactMatch and caseOnlyDifference when unequal spellings become equal under JavaScript lowercase.1
UCUM defines a case-sensitive symbol representation. Lowercase similarity is therefore a spelling diagnostic, not a justification for changing the case of a clinical unit code.2
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstUnit | First Unit | Required. Text; maximum UTF-16 length 8192. |
| secondUnit | Second Unit | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| exactMatch | Exact Match | Required. Boolean. |
| caseOnlyDifference | Case Only Difference | Required. Boolean. |

"caseOnlyDifference": true
}
}Limitations and assumptions
- Case similarity is a diagnostic rather than permission to normalize units; full unit grammar, prefixes, dimensional equivalence, and safe conversion are not evaluated.
- 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 relevant full standard, implementation profile, and validated parser when interoperable or clinical record validity matters.
