I'm currently mapping local lab medicine vocabularies to CDM Measurement/LOINC domain vocabularies.
Here, one local source concept (EBV VCA/EA IgG(Brain death patient KONOS)) seems to be the combination of EBV VCA (capsid) IgG and EBV EA (early) IgG. So I've mapped this source concept to two target concepts, namely "3036456 Epstein Barr virus capsid IgG Ab [Titer] in Serum" and "3007241 Epstein Barr virus early IgG Ab [Titer] in Serum".
In short, I've mapped one source concept to multiple target concepts. I wonder if such mapping logic could be recommended.
Although I've read several articles regarding one-to-many mappings, I'm not 100% sure that I'm doing the right thing. Please let me know if I'm making an error.
Thank you in advance
