A researcher at Cape Cod hospital checks the labels on blood samples before running tests on them. Donated blood is separated in a centrifuge by lab technologists at CCH into two products - packed red blood cells and fresh frozen plasma. Red cells are used for anemia and elective and emergency surgery, and for massive blood loss due to trauma. Plasma is used for burn victims, and for bleeding disorders. A third blood product, platelets, is purchased by the hospitals. Platelets need to be kept moving at all times, so they are stored in a small incubator at room temperature on a shelf that continually agitates the product.
