Living Donation Types

Positive Crossmatch

The positive crossmatch process is similar to the process used for ABO-incompatible living-donor kidney transplants, where patients can receive kidneys from living donors with blood types incompatible with their own. Similarly, treating patients with plasmapheresis also greatly reduces the chance of organ rejection in patients with elevated antibody levels. Previously, these elevated antibody levels made tissue rejection almost certain. Positive crossmatch live donor kidney transplants are usually only performed if no other live donors (with a negative crossmatch) exist.
