Just caught another thread - made me wonder...is fasting necessary before blood tests. Wouldn't be a problem as I am rarely hungry. I am going tomorrow so thought I would ask. Never have fasted before.
It depends Lilly - if there is anything on there about serum or urine osmolality then there is no water (boy does this one suck big time!) It could be a test given if your doc is trying to screen out a kidney problem or the onset of diabetes. Your doctor should tell you this when you get the lab sheet, though - pretty sloppy of her/him not to.
A foolish consistency is the hobgoblin of little minds.
