To avoid discrimination, everyone should be tested.

I am a doctor, and as far as I know, routine drug testing of people being admitted to hospital does not take place.

However, surgeons often order Hep and HIV testing for people about to undergo surgery, which I think is fair enough; there is some evidence that there is a risk to surgeons and all theatre staff, depending on the surgery.
