@fdimartini Thanks for your input. Please correct me if I am wrong.
source_vocabulary_id has constraints with vocabulary table. so the vocabulary_id should be something like “LOINC”, “SNOMED”, etc.
Are you suggesting to map “21465” “WBC” to concept_id from “SNOMED” vocabulary
and “21465” “RESTRICTED PEAK ALPHA, URINE” to concept_id from “LOINC” vocabulary?
or to add own vocabulary in vocabulary table like “EPIC-Lab” as vocabulary id?
