I read on Web MD that drinking less than 8 hours before a fasting blood test can affect results. Does this include drinking water?

I'm 63, male, and often will get up 1-2 times in the middle of the night to urinate. I've started drinking a couple swallows of water each time, to hydrate and allow the body to eliminate toxins. What does everyone think of that? Will this affect test results?

My doctor says it's OK to drink clear, calorie free liquids before a fasting glucose test. She would prefer that than for me to be dehydrated.
