International Rare Donor Panel

The International Rare Donor Panel (IRDP) was conceived under a joint World Health Organisation (WHO) and ISBT initiative in 1965 to facilitate the rapid location and exchange of rare blood between countries.

The panel currently contains details of rare donors from 27 contributing countries and also frozen unit inventories from frozen blood banks around the world. The compilation and maintenance of the IRDP is carried out by the Red Cell Reference department of the IBGRL in Bristol, UK.
