In the present scenario, we require ave donor. After specific cross-matching, then donation is decided once it matches and there is no reaction during cross-matching. If you cant find it in hospital blood bank, you can get it from any blood bank outside. The outside blood bank is responsible for cross-matching. Blood, even if collected from family members is used only for replacement purpose, to avoid transfusion associated graft versus host disease. Any further queries, happy to help again.
