Modern blood donation and component processing are highly regulated processes that enable the safety of transfusion for the patient. Clinicians should use blood transfusion judiciously, only using the necessary component and necessary amount and only when truly clinically indicated. The use of arbitrary triggers is discouraged, and the decision to transfuse blood products should be based on the sum of clinical data, rather than based only on a numerical hemoglobin measurement or a platelet count.
