the concept_name is standardized pt of drug reaction.but the concpet_name is not match the pt of MedDRA.example: “idiopathic hydrops fetalis” in concept_name inplace of “hydrops fetalis” in MedDRA.
Not sure what you mean, @seanzhang924926. What’s a “pt”? Equivalent MedDRA and SNOMED don’t have to have a matching concept_name. SNOMED calls it “hydrops fetalis” and MedDRA has a Preferred Term “Hydrops foetalis”, which is the British rather than American spelling of the same thing. MedDRA also has a “Hydrops fetalis” as an Lower Level Term. “Idiopathic hydrops fetalis” is a different SNOMED concept.
