Are they on a first come first served basis, or is there a criteria for deciding who is next on the list?
I'd guess urgent priority towards the top, but its obviously also based on compatibility with the organs available. Could do with a new liver myself like...
As far as I am aware Compatability is what is looked at and then the list will be checked to see which patient on the waiting list needs the transplant soonest. I'm not sure but I think that children are still given priority over older patients. http://www.uktransplant.org.uk/ukt/about_transplants/organ_allocation/kidney_(renal)/renal_organ_sharing_principles/renal_organ_sharing_principles.jsp#b2
