  3. David - always do this. it makes the veins stand up. if it is a non fasting test, drink some coffee/tea/chocolate before the teat to raise your blood pressure.

  4. Arezoo - n general, it is recommended that you fast - nothing to eat or drink except water - 8 hours before having a blood glucose test. In persons with diabetes, glucose levels are often checked both while fasting and after meals to provide the best control of diabetes. For random, timed, and post-meal glucose tests, follow your doctor's instructions.

  5. John W - Drinking water helps with the blood draw so it's a good idea. You only have to avoid other drinks and food when you have fasting tests which often isn't the case. I get blood tests every two weeks because of congestive heart failure, on occasions there may be a fasting test but for the most part they're not. The H1A1C blood test often used to gauge a diabetic's control is not a fasting test.

  6. Kai - Usually yes. I suppose there might be some blood tests where they don't want to ingest ANYTHING but for most blood tests having a bit of water is not a big problem and is better then getting getting dehydrated. Considering if you sleep for 8 hours, and usually people haven't eaten for a couple hours before bed, then getting to and waiting in line at the blood lab, you're talking about 10-12 hours which is too long to go without some water.
