According to Kevin, MD.
This is particularly funny to me because the Significant Other and I are always commenting throughout every episode of House, "What, they don't have MRI techs to do MRIs?" Or, "What, they gotta do their own urinalysis?"
We have definitely noticed that the three cute young doctors on house seem to do very little thing themselves. And that it didn't really seem all that, how shall I say, realistic.
The again, we knew we were watching TV, so we weren't exactly looking for stark realism.
