An update - after a very early start everything went well. There were various procedures before the actual test, which just involved me lying on my front on a bed for 15 mins. I don't think the camera even passed over me.
Then back to the waiting room and 10 mins later the Doctor came and told me all was fine TG and we could go home !
So it was 2 hours - 9.30 to 11.30.
I was told if there had been any doubts I would have had to come back for a retest in the afternoon.
So grateful for the wonderful care here.
