International Society of Blood Transfusion

The International Society of Blood Transfusion (ISBT) is a scientific society, founded in 1935, which aims to promote the study of blood transfusion, and to spread the know-how about the manner in which blood transfusion medicine and science best can serve the patient's interests. It organizes international conferences, and advocates standardisation in the field of blood transfusion, such as standardized bar coding of blood for transfusion using the ISBT 128 standard for blood products, and classification of human blood group systems.
