"Series Of Routine Tests"

Get annoyed that journalists just pass along nonsense. Really the only "test" they can do at the hospital that they can't at his residence is a scan. He's in the hospital because he's 5 minutes away from needing to be intubated (which might not actually happen) and they want to be ready.

The PM was taken to a London hospital on Sunday evening with "persistent symptoms" - including a temperature - for a series of routine tests.

It is said to be a "precautionary step" taken on the advice of his doctor.
