What I know is this. For each donor organ, they rank everyone one on multiple factors including compatibility, time on list, age, location, etc. Then they call up the first individual on the list and see if they are interested. If they don't get a confirmation in some time, they go to the next individual down the list. I know of one individual who didn't reply soon enough and missed out. The next match they got was 2 years down the line but it was a very good match. Edit: I think they do call up a couple people on the top of the list but the highest priority that calls in the time allotted will get it. Again this is still a mystery to me since I'm only half way through my wait time on list so no inquiries up to now.
