What do they do if they can't find a vein?If the medical staff does not see a vein that will work for a blood draw, they may take blood from another location. Depending on the protocols of the lab, clinic, or doctor's office, they may be able to do a blood draw from the top of the hands, wrists, and other areas on the arms.
What happens if you draw blood without a tourniquet?Performing venipunctures without tourniquets is not an option. Constriction of the circulation causes veins to distend as they fill up with blood that can no longer circulate. Distended veins are easier to palpate and access.
