Drink lots of water before a blood draw to make it easier to find a vein.
Are you a tough needle stick? You can help a phlebotomist out by pumping your veins up the natural way.
Many blood tests require that you fast for some hours beforehand, but that usually means for everything but water.
If you drink a lot of water in the hours before a needle stick, your body will be well-hydrated and your veins should be much easier to find. Check with your doctor’s office to be sure, and when you get the OK, drink up.
