Blood sampling. Venous blood sample being removed from a person's arm with a vacutainer. This is a device which sucks blood out of a vein once it has been punctured. A white tourniquet is tied around the patient's upper arm (top right). This is to trap blood in the lower arm and enlarge the vein making it easier to pierce. Blood samples are subjected to a battery of tests in order to confirm diagnosis or identify disorders.
