Mrsa and surgery

So I had my pre op this morning for abdominal hysterectomy next Thursday she had asked if I've stayed overnight in hospital recently to which I replied yes 2 days last week before my isolation started she then sent someone to my house with the mrsa body wash and nose solution although I have not tested positive and told me ile be put last on the theatre list and barrier nursed now. Eh???? I hope they don't cancel!!
