@paul55 When we are dehydrated, our whole system reacts in specific ways. You can visually see that with the color of our urine. Good hydration will show a light yellow, the darker the color, the more concentrated. While I am on a 2 liter [about 64 ounce] restriction per day, I have to spread it out in that 24 hr period. Difficult to do in the heat of summer!

For me, I typically fast before any bloodwork, and try to schedule it early in the morning. Then treat myself to breakfast! Recently a tech at my cancer center told me to be nicely hydrated the evening before the draw, as it makes getting any sample easier on the veins. Oh, and do not make a fist at the draw; it affects a few factors with the muscle contraction. Who knew?! I keep to my regular activity schedule. Not too sure about the meds, but I do keep to my regular time to take them, seeing that is early morning.

Does this help answer your question?
