How long should I fast before having blood work done at 8am tomorrow? ?!

The rule of thumb is only water after 8 pm and no food until after the blood work.

Effectively, you have to fast for at least 12 hours before the blood test but you are permitted to drink water during the fast.

nothing after midnight. If you need to take a pill or something a tiny bit of water, nothing that has sugar,or, caffeine. So, no soda, coffee, tea, milk, juice, etc. Just a bit of water.

For blood work, you should not eat 6-8 hours before. Drinking water is fine and encouraged because it will allow the veins to show better/be fuller so you won't get poke you too much trying to find a good spot.

You should fast for 12 hours. You can consume anything that isn't full of fat like a salad, fruits, or vegetables

I have blood work done a lot >_>

if you been told to fast then nothing if told not to then eatas normal.but midnight about right give yourself six to eight hours
