Here on the Africa Mercy for our hospital, we do not have a blood bank. Blood is needed on some more of the major maxillofacial surgeries. Instead, we, the crew, volunteer to be tested and available for donation when needed. Sometimes you know ahead of time and other times you get an urgent call from the lab to meet them in the ICU in order to donate as a patient is in the operating room who will be needing your type of blood. My friend took this photo after my most recent donation of one unit of A+ blood.
