The International Rare Donor Panel (IRDP)


The panel 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 and currently contains details of rare donors from 27 contributing countries and 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. In 2020 NHSBT led a project to upgrade the International Rare Donor Panel database and functionality on behalf of ISBT. 

The new IRDP site was launched by IBGRL in December 2020 and can be accessed here.
