Problem statement
Medical fax automation can use OCR to extract laboratory text, but local laboratory names are not standardized. The same test may appear as an abbreviation, spelling variation, or facility-specific label.
The system must address three blockers:
- Synonymy: terms such as
LDL,LDLC, andlow-density lipoprotein cholesterolcan refer to the same clinical measurement. - Polysemy: similar labels can represent different measurements.
LDLandLDLPmust not be treated as equivalent without property and unit validation. - Elation strictness: the downstream payload requires a valid LOINC code in
test.loincfor structured, trendable filing.
The module therefore treats a LOINC code as a validated clinical interpretation, not merely a string-similarity result.
