What medical department does Gregory House lead in House M.D.?

Gregory House leads the Department of Diagnostic Medicine in House M.D. at Princeton-Plainsboro Teaching Hospital.

The department handles complex cases that other doctors have been unable to diagnose. House and his fellows assemble symptoms, test results, patient history, and unusual clues to identify an underlying disease. The department’s work is the engine of the show’s weekly medical mysteries.

Diagnostic medicine is a real area of clinical practice, although the show presents House’s department in a particularly dramatic and unusually self-contained form. House is a board-certified diagnostician with specialties in infectious disease and nephrology, but his day-to-day role in the series is leading the diagnostic team. The department should not be confused with neurology, oncology, or cardiology, which are separate specialties represented by other doctors at the hospital.
