how to be tested as a kidney donor
Blood transfusions, pregnancy, previous transplant(s) or a current infection can cause your immune system to be more aggressive. Crossmatch Testing â When a kidney is available, your blood and the blood of the donor kidney are tested. With a negative crossmatch, (no reaction) you are compatible with the donor. A positive crossmatch (reaction) the kidney will not work for you because it is incompatible.
