The hemorrhagic manifestations of thrombocytopenia can be effectively controlled by the infusion of human platelets1 but the hemostatic effect is relatively transient. Despite this limitation, platelet transfusion can be used to prepare the thrombocytopenic patient for emergency surgery and to control thrombocytopenic bleeding which occurs prior to, or in spite of, adequate "steroid" therapy. These emergencies require immediate treatment, but the usual methods for the preparation of platelet concentrates, platelet-rich plasma, or platelet-enriched whole blood incorporate techniques which are not available to the usual hospital blood bank, i. e., low-temperature processing, special anticoagulants, and the immediate availability of compatible blood donors. The inference that these latter techniques are essential to obtain viable platelets has deprived many hospitals of a valuable therapeutic tool. McGovern2 has shown that low-temperature processing and special anticoagulants are not essential, but his method necessitates the immediate availability of compatible blood donors. It is our
