The site says that Caucasians have a 97% likelihood to find a match, not including stem cells from umbilical cords (which leads to a slower recovery time and thus a higher chance of infection but less likelihood of graft-vs-host disease). And while I am Caucasian, I'm not of European descent, which is what most of the registered members of BTM are. I sort of have contacts at the main hematology unit at a Tehran hospital and many cousins. Iran is part of the international group of registries in BMDW, but I'm not sure how easy it would be to get someone from Iran here. Humanitarian things like this should get someone a visa, if necessary, I'm hoping.
