koori: if the cordblood is not used, you still can retrieve for your bb if needed later for a hefty amt of $$. But, you probably have insurance to cover the expenses then. I am not sure if they will inform you if there is a match for other patient. To be frank, the chances is very low for a match.. Also, i will be having another bb soon after.. so probably they can use each others' cord blood also.
BTW , once you put into a pte bank, you cannot transfer to public bank.. So you have to continue paying yrly for as long as your bb lives ?
