Fast or not.......that is for the Hospital to decide. You will have to ask them before you go as it all depends on what type of tests you are going for ..........
Hi I'm relatively new at this game too. If they gave you one of what appears to be standard blood test forms, there should be a box somewhere that asks about glucose and next to it may ask random or fasted a similar question may be against Lipids. If you are in any doubt ask your hospital or diabetic clinic.
