What is Dr. Gregory House’s medical department at Princeton-Plainsboro in House M.D.?

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

The department specializes in solving unusually complex cases that remain undiagnosed after routine medical evaluation. House and his fellows review symptoms, medical histories, laboratory results, imaging, and possible treatments before testing competing explanations.

Diagnostic medicine is a real area of clinical practice, but the show dramatizes it through a highly concentrated team model. In ordinary hospitals, diagnosis is usually shared across specialties rather than handled by a single physician who personally directs every unusual case.

House is also described as a specialist in nephrology and infectious disease. Those are his formal medical specialties, while Diagnostic Medicine is the department he heads at Princeton-Plainsboro. This distinction matters because questions about House’s “specialty” can have two answers depending on whether they mean his board specialties or his hospital department.
