6 hours i believe is the standard before having blood work. I've sometimes cheated with an apple juice, but in general you should drink only water, and dont over hydrate! this could thin the blood just enough to disrupt testing.

No From personal experience, I would say no. I have RA and I had to have a ton of blood work and none of the times did I have to fast first. That being said, I would check with your doctor who ordered the labs to be sure, because new tests develop and the requirements for different tests may vary. I am in the same boat and have never been requested to fast before having tests.
