I was just looking at my paper work.....It say GB patients must fast prior to lab work.....does that mean no water either........ fasting..........is it 12 hours before lab work....... right.....
Usually they say no food after 7 pm. I think water should be ok though, just call and make sure. If you can't have any water make sure you hydrate really well tonight so your veins are nice and plump. (easier stick)
