Thanks again for the reassurance. I actually called the transfusion department today to inquire about banking DH blood and the assured me that they will have no problem finding the right blood for him. The lady also said brain surgery is not a surgery that typically needs blood. She was very sweet as I sobbed on the phone. I am thankful for all the info you have given me and that you took the time to clarify the info. It means more then you know!
