You may have heard discussions about “matching” and kidney transplantation. There are actually three tests that are done to evaluate donors. They are blood type, crossmatch, and HLA testing. This blood test is the first step in the process of living donation and determines if you are compatible or a “match” to your recipient. Blood Typing
How Does the NKR Find the Best Donor-Recipient Match for Kidney Transplants? Reduce the risk of de novo DSA formation. Lower the probability of rejection. Lower the probability of graft failure. Lower their immune-suppression dosage.

For the kidney to be a good match, the new kidney will need to be very similar to the other organs and tissues in your body so that your immune system will not attack it. The job of your immune system is to find anything that should not be inside your body, attack it, then get rid of it to keep your body healthy.
Because you’ll need to find a compatible kidney donor, a blood relative may be your best match—though a kidney could also come from a close friend, acquaintance, or co-worker. Talking openly about your donor search can help identify possible donors. Place your name on the kidney transplant waiting list to receive a donor kidney.
The best match for the recipient is to have 12 out of s12antigen match. (This is known as a zero mismatch.) It is possible for all 12 markers to match, even with an unrelated deceased donor organ, if the patient has a very common HLA type.
For example, if a kidney becomes available, UNOS will first try to find a match in the OPO where the kidney is being donated. If no match is found there, UNOS will search within the larger region. If no match is found within the OPO or region, the kidney will then be available to someone who lives outside the region.
Transplant Screening Tests. Regardless of the type of kidney transplant you may undergo – living or cadaveric – special blood tests are needed to determine the kind of blood and tissue you have. These test results help to match a donor kidney to your body.
This translates to an additional 26% mean kidney life years (50 HLA Match Points adds 11%, Donor Age < 55 adds 9%, Donor Age 22 Years Younger adds 6%). One may also ask, what blood types are compatible for kidney transplant? Kidney donors must have a compatible blood type with the recipient.
