What medical specialties does Gregory House hold in House M.D.?

Gregory House holds specialties in nephrology and infectious disease in House M.D.

House’s formal medical background helps explain his role as a diagnostician. Nephrology focuses on the kidneys and related disorders, while infectious disease concerns illnesses caused by bacteria, viruses, fungi, parasites, and other pathogens. Both fields can involve complicated systemic symptoms that require broad medical reasoning.

The series presents House as a physician who leads a diagnostic medicine department, applying knowledge across many specialties rather than practicing only within one narrow field. His team consults specialists when a case requires surgery, neurology, oncology, or another discipline.

A common mix-up is calling House a neurologist or surgeon because those departments appear frequently in the show. House is not the hospital’s neurologist; Eric Foreman is a neurologist, while Robert Chase is a surgeon. House’s established specialties are nephrology and infectious disease.
