In House M.D., what medical specialty did Gregory House share with nephrology?

Gregory House’s medical specialties in House M.D. are infectious disease and nephrology.

House is introduced as the head of diagnostic medicine at Princeton-Plainsboro, but his formal expertise is especially associated with infectious disease and kidney medicine. The combination supports the show’s recurring stories about systemic illness, unexplained infections, and organ failure.

House’s specialty is sometimes simplified by calling him only a diagnostician. Diagnostic medicine is his department and role, while infectious disease and nephrology describe his medical training and expertise. This distinction matters because the series often brings him cases after specialists have failed to identify the underlying condition.

The character’s name and methods also reflect the show’s Sherlock Holmes influence. Like Holmes, House notices small clues, challenges conventional explanations, and uses deduction to connect apparently unrelated evidence.
