One of the main activities of ISBT is the Regional and International Congresses. ISBT congresses comprise plenary and parallel sessions with invited speakers and selected oral presentations on state of the art topics in the field of transfusion medicine. The ISBT congresses also provide networking opportunities and the prospect to connect professionals with industry and vice versa. ISBT is committed to holding its congresses around the world. The two Regional Congresses (one of which is held in Europe) are held in odd years whereas the International Congress is held in even years. For past congresses click here. The Congresses are organised in collaboration with a local (national) blood transfusion society or institute. In December, four years before the year of the Congress a “call for expression of interest for hosting an ISBT Congress” will be made available on the ISBT website and will be announced through various communication channels.
