3) Crossmatching
This is part of blood compatibility testing, it is simply applying the two previously mentioned ideas by a simple test. Crossmatching involves mixing a sample of the recipient’s blood plasma with a sample of the donor’s red blood cells. If the crossmatch is positive, it indicates that antibodies exist against the donor.
The recipient should not get this kidney unless a specific therapy to lower antibody levels is provided prior to transplantation. If the crossmatch is negative, it suggests that the receiver has no antibodies to the donor and is subsequently able to receive this kidney.
