Unlike in Britain, at least some years ago. When I had to have an operation, I was told that a routine test for the surgeon's protection was an HIV test, but they needed my written permission to perform it. I agreed, but so long as they told me the result. They informed me that they were not allowed to tell me. I said that in that case they couldn't do the test. I'm sure they went ahead anyway once I was anaesthetised. Hopefully their internal procedures have improved a bit since then!
