For most people who require a transplant, the initial phase in accepting a transplant is to get on the national transplant waiting Kidney Donor List for a transplant from an expired donor. The United Network for Organ Sharing (UNOS)* Organ Center keeps up this rundown. All transplant competitors who don’t have the alternative of a living contributor (and even some who do) more often than not sit tight for some time allotment because there are insufficient giver organs for all who require them.
