In House M.D., what is the name of Dr. House’s department?

Dr. House heads the Department of Diagnostic Medicine in House M.D. The department is the fictional hospital unit where he assigns teams to investigate difficult cases.

Unlike departments organized around one body system, diagnostic medicine in the show draws on many fields. House’s doctors use laboratory work, imaging, patient histories, and specialist consultations to test competing explanations. Their cases usually begin with symptoms that could belong to several diseases.

The department’s name is sometimes mistaken for internal medicine, because House is an internist and many cases involve whole-body symptoms. However, the show consistently identifies his hospital unit as Diagnostic Medicine. Princeton-Plainsboro’s administrators also treat the department as unusual because it handles rare cases and depends heavily on House’s individual approach.
