Continuity: 4-86: "Wilson's Heart": Throughout both parts of season 4's finale ("House's Head" and "Wilson's Heart"), Amber is always shown getting hit from the back and sitting facing House – so her seat back is to the windows. Yet the last time we see the accident, that is, right after she took the flu pills, she is definitely sitting neatly sideways to the window and getting hit from the right side. It most likely was done for artistic reasons, as the back shot makes for a very neat effect, with her blonde hair flowing around her like sunrays.

Continuity: "Living The Dream": House says that someone's rate of reading sentences has dropped from 2.1 sentences per minute to 2.9.

Continuity: In the episode that aired on 27 March 2008 in the UK, House has the shot glasses next to each other. Camera changes after a few seconds where you can see House's hands, and the glasses are no longer apart.

Factual error: In episode 414, "Living the Dream," the patient Evan is given a nerve function test. We see Cutner and Taub performing the test by puncturing Evan's legs with needles. Modern nerve function tests actually rely on electrical impulses from a small computerized device, with no needles necessary.

Continuity: Most of the time, whenever House puts down his Nintendo DS, the angle at which it is bending changes. For example, in one shot, it is not bent at all and in the next it is almost closed.
