The blood type puts the person into different lists for kidney transplantation. In
Nebraska, a person with a blood type A will wait less time than a person with a blood type of O or B. This applies to cataveric transplant recipients. If a person has a living donor, then the waiting time can be a lot less, compared to cataveric.
If you have a person interested in donating a kidney to you, then you have to first be evaluated by the transplant center to see if you are a candidate.
