What medical specialty does House claim alongside diagnostic medicine in House M.D.?

In House M.D., Gregory House is board-certified in nephrology and infectious disease. These specialties form part of his professional background alongside his leadership of diagnostic medicine.

Nephrology concerns the kidneys and related conditions, while infectious disease focuses on illnesses caused by pathogens and other infectious agents. Both fields are especially useful in the series because unexplained kidney problems, fevers, and systemic infections frequently appear in House’s cases.

House’s diagnostic department is fictionalized as a specialty built around solving rare or unusually complicated cases. His team draws on many fields, including neurology, oncology, immunology, and surgery, when testing possible explanations.

The wording matters because House is not described as being board-certified in every specialty represented by his team. Eric Foreman is a neurologist, James Wilson is an oncologist, and House’s stated specialties are nephrology and infectious disease.
