What medical specialty does House head at Princeton-Plainsboro in House M.D.?

House heads the Department of Diagnostic Medicine at Princeton-Plainsboro in House M.D.

The department specializes in solving complicated cases that remain unexplained after routine examinations and tests. House leads a small team of physicians who generate and test competing diagnoses, often using clues from symptoms, medical history, imaging, laboratory results, and unusual environmental exposures.

House is also described as a specialist in infectious disease and nephrology, but those are not the name of the department he directs. The diagnostic department is the show’s fictional centerpiece and gives the series its case-solving structure.

The format resembles detective fiction: the team gathers clues, proposes hypotheses, eliminates possibilities, and revises its conclusions when new evidence appears. In real hospitals, diagnostic medicine can involve multidisciplinary consultation, but House’s department and methods are dramatized for television.
