To take the blood sample, a tourniquet (elastic) band is placed tightly on the upper arm. The patient is asked to form a fist. This helps in the buildup of blood filling the veins and it becomes easy to collect the blood. The skin is cleaned before inserting the needle in the vein in order to prevent bacteria from entering.
