In House M.D., which fictional diagnosis department does House direct at Princeton-Plainsboro?

In House M.D., House directs Princeton-Plainsboro’s Department of Diagnostic Medicine.

The department is the professional base for the show’s central diagnostic team. Patients are referred when ordinary testing or specialist consultations have not explained their symptoms. House assigns investigations, challenges proposed diagnoses, and often orders risky tests to find the underlying cause.

The department’s membership changes over time. The original team includes Eric Foreman, Robert Chase, and Allison Cameron, while later seasons introduce doctors such as Chris Taub, Remy Hadley, and Lawrence Kutner. The changing teams provide different medical viewpoints and create recurring workplace conflicts.

This fictional department should not be confused with House’s individual specialties. House has expertise in infectious disease and nephrology, but he leads Diagnostic Medicine. The department’s unusual independence and prominence are narrative devices that let the series focus on rare, multi-system cases.
