Phlebotomy is the process of extracting blood from the body to be tested or analyzed. It is usually done at hospitals or doctor's offices but can be done nearly anywhere. The circulation is restricted to the arm, a vein is located, and then a needle inserted into the vein. Blood is drawn into a syringe or vile where it can be delivered to a laboratory.
