[Hospital blood bank: information system and immuno-hematology].

Due to regulations, hospital blood banks have to equip them with a computer-based information system. This system facilitates the management of the blood bank and ensures the safety of the storage, issuing and traceability of the blood and blood components. It permits to create a medical file for each transfused patient, which contains the characteristics of the blood components transfused and the immunohematological status of the patient, received by electronic data interchange from the blood establishment. Thus, from the assistance to the prescription of blood transfusion to the issuing and traceability of the blood components, the computer-based information system is the guarantee of the transfusion security in a hospital blood bank.
