What does the medical abbreviation RE mean?

Answer 1

As with most medical terms, it depends on the context. It might be used as an abbreviation to reference a body part such as Right Extremity or Right Eye (this is also abbreviated "OD" for Oculus Dextra), or, less often, Right Ear (often this is abbreviated "AD" for Auris Dextra).

If written "RE:" or "re:" it can be the abbreviation for "regarding", as is also used in other non-medical contexts.

As an acronym, instead of an abbreviation in medicine, other possible meanings of "RE" include Reflux Esophagitis, Regional Enteritis, Rectal Exam, Reproductive Endocrinologist, Routine Examination, Reflex Epilepsy, Reading Epilepsy, Reticuloendothelial, and Rasmussen's Encephalitis. This is only a partial list of potential meanings, depending on context.
