One of my relatives, 50 year old female, needs a
kidney transplant (2nd time). She is on dialysis now (3 times a week). First Kidney transplant done in 2010.
Her blood group is O+ve.
The donors who are ready in her blood line are AB+ and B+.
Is blood group compatibility absolutely essential for this transplant?
Should we continue to wait for an O+ donor or is it possible to go for a transplant with a blood line donor with a different blood group?
